Breaking News


Looking for an enthusiast gaming and overclocking board? Look no further than the GIGABYTE X58A-UD7 motherboard. With latest technologies including SATA 3 and USB 3.0, and high quality components, it is definitely one of the top motherboards on the market.

Introduction – Gigabyte X58A-uD7

As one of the world’s leading motherboard producers, GIGABYTE’s main focus in the motherboard industry is staying up to date with the latest technologies and using the highest quality components in manufacturing. They have consistently shown that they are capable of this, being the first to support USB 3.0 and SATA 3, and providing 3x more power to their motherboards’ USB ports. They have expanded these features to be built into their latest mainstream Intel and AMD motherboards, ensuring that these features are available to even those who cannot or do not purchase high-performance motherboards. Notwithstanding these improvements, GIGABYTE’s price tage for the X58A-UD7, a whopping $340, raises some eyebrows.

Considering that the UD7 is one of the top model motherboards in the Intel platform socket LGA1366, it makes sense for it to be priced at around $340. It is not the overall price that causes concern, but the price disparity between the UD7 and its predecessor, the UD5. The UD5, with an MSRP of $290, also comes with 16 Phase Power, 2x Gigabit LAN, and Unlocked Power features. The only big difference between the two is the cooling solution used in the UD7. The UD7 comes with the Silent-Pipe 2 cooling solution, which we will examine closely in the following pages. It includes not only an extra heatpipe cooler that attaches to North Bridge heatsink, but also an extra water cooling block that can replace the stock heatsink. Similarly, the UD3R, which is about $210, uses 12 Phase Power, no full heatpipe cooling solution, 1X Gigabit LAN, and no Unlocked Power features. From these differences in price, we can infer that the UD7 is specifically designed for gamers and overclocking enthusiasts, the UD5 is one step lower, and the UD3R provides plenty of performance for avid gamers but perhaps a bit less on the overclocking side.

As we previously mentioned, the UD7 supports USB 3.0, SATA 3, provides 3x more power to the USB ports, and is also compatible with Multi-Display support with 3-Way SLI and CrossFireX configuration. It uses 16 Phase power for optimal cool and stable operation, and is compatible with unlocked processors for the ultimate overclocking experience. The Ultra Durable 3 motherboard design is GIGABYTE’s specialty, using 2x more copper in the PCB for less impedance, lower temperatures, better power efficiency, lower EMI, better overclocking, and better ESD protection. The Ultra Durable 3 design also includes high quality Japanese capacitors, Lower RDS(on) MOSFETs and Ferrite Core Chokes. Finally, the Rev 2.0 UD7 is fully compatible with the new Intel 6 Core 32nm Gulftown processors, and comes with ON/OFF Charge feature for easily charging removable devices like iPods. It also has LEDs that show temperatures, voltages, and other information on the motherboard for overclockers.

Ultra Durable 3
GIGABYTE Ultra Durable 3 design, featuring 2 ounces of copper for both the Power and Ground layers which dramatically lowers system temperature by delivering a more efficient spreading of heat from critical areas of the motherboard such as the CPU power zone throughout the entire PCB. GIGABYTE’s Ultra Durable 3 also lowers the PCB impedance by 50%, which helps to reduce electrical waste and further lowers component temperatures. A 2oz Copper layer design also provides improved signal quality and lower EMI (Electromagnetic Interference), providing better system stability and allowing for greater margins for overclocking…more

Benefits of 2 oz Copper PCB
• Cooler than traditional motherboards
• Enhanced durability
• Improved energy efficiency
• Greater margins for overclocking…

2X Lower Impedance

In addition, doubling the amount of copper lowers the PCB impedance by 50%. Impedance is a measure of how much the circuit impedes the flow of current. The less the flow of current is impeded, the less amount of energy is wasted. For GIGABYTE Ultra Durable 3 motherboards, this means total PCB electrical waste is reduced by 50%, which also means less heat is generated. 2 ounces of copper also provides improved signal quality, providing better system stability and allowing for greater margins for overclocking.

50,000 Hours Japanese Solid Capacitors
GIGABYTE Ultra Durable motherboards are equipped with solid capacitors developed by leading Japanese manufacturers. With an average lifespan of 50,000 hours, these solid capacitors provide the stability, reliability and longevity essential to meet the power needs of high-end processors and other components running today’s most demanding applications and games…more

* 50000 hours of work time is calculated at 85℃ ambient temperature.

Hardware OverVoltage Control IC – Enabling Extreme Overclocking
GIGABYTE Hardware Overvoltage Control ICs featuring more voltage control options than before for the CPU North Bridge and memory. The overvoltage controllers also provide hardware linear real-time voltage control, which means there is no delay compared to the GPIO controller in past implementations. In addition, GIGABYTE’s Hardware Overvoltage Controller ICs also allow for much finer voltage control, allowing power users to adjust voltage in as little increments as 20mV for better overclocking performance.

ErP Lot 6 support
The ErP (as known as Energy-Related Products Directive) is part of new European Union’s environment regulations. ErP established is based on the concern of environmental issues regards electronic devices been gained popularity and how to improve energy efficiency for better and greener life. GIGABYTE presents standard motherboards to help you effectively improving system performance and saving more energy.



According to GIGABYTE, the UD7 is compatible with DDR3 2200MHz memory modules. We will test that statement, but our main benchmarking setup will use 1600MHz memory modules. To test the 2200MHz memory speeds, we are going to be using slightly slower Kingston 2133MHz DDR3 4GB KHX2133C9AD3W1K2/4GX modules.

Unfortunately, the UD7 only uses a standard onboard audio bus. The $340 price tag would be more appreciable if GIGABYTE would include a dedicated audio card for those who want crisper sounds and high performance. Finally, it would have been better for GIGABYTE to include a connector where users could plug in all the case cables, such as the Power Switch, Reset Switch, and LED connectors, and then use that larger connector to simply connect one collection of cables to the motherboard.

Software and Features Quick Overview

Here are some great applications that GIGABYTE includes with the UD7 motherboard. Most of these applications also come with other model motherboards, including the Intel platform X58, P55, H57, H55, P45, P43 G41 series motherboards, and AMD 800 and 700 series motherboards. For more information about certain features, please make sure to check on GIGABYTE’s website to see if the motherboard supports those features.

The descriptions provided by GIGABYTE do an excellent job explaining what each of the applications do. In the interests of thoroughness, however, we note that the Dynamic Energy Saver 2 feature would freeze our system every single time we enabled it. Under stock settings, when the computer is stable, the Dynamic Energy Saver 2 worked very well. It comes with a very nice counter that shows exactly by how many kilowatts the application has reduced the computer’s energy waste.

Dynamic Energy Saver™ 2
GIGABYTE Dynamic Energy Saver™ 2 incorporates a host of intelligent features that use a proprietary hardware and software design to considerably enhance PC system energy efficiency, Reduce power consumption and deliver optimized auto-phase-switching for the CPU, Memory, Chipset, VGA, HDD, and fans with a simple click of button.

Checking out the X58A-UD7

Click Image For a Larger One
The GIGABYTE X58A-UD7 comes in many layers of packaging to make sure everything arrives in good physical condition. In the first two pictures, the outside boxing for the X58A-UD7 is visible. The time that went into designing the graphics on the motherboard’s box does make this motherboard quite attractive for the buyer. It also has all the main features mentioned, like the 333 Onboard Acceleration which includes USB 3.0, SATA 3, and 3x more Power output for USB 3.0. We can also see the 16 Phase Power and the Ultra Durable 3 motherboard design. There is a sticker saying “ON/OFF charge” on this cover, but it is a bit difficult for users to understand what this really means unless they have previously read the description of this feature. GIGABYTE includes the Hybrid Silent-Pipe 2 cooling solution which is not available on lower end motherboards. We’ll take a look at the Hybrid Silent-Pipe 2 further down this page. On the back of the motherboard’s box there are further explanations of the features this motherboard comes with.
Click Image For a Larger One
The packaging also shows Unlocked Power and support for Core i7 Socket 1366 6-core processors. What this means is that this motherboard supports unlocked processors, and can also deliver enough power to run an extremely overclocked system. On the second picture we see that the front of the motherboard’s box can be opened to show the actual product inside. On the inside flap of the box, most of the features that were explained on the back are also visible here. One really nice addition to the boxing of this motherboard is the handle on the top. This makes it very easy to transport the board from one place to another. Users could even use the box as a briefcase after taking the board out.

When the X58A-UD7 is taken out of its main cover, we are presented with a hard cardboard box that keeps the motherboard and its accessories snug. When the white box is opened up there are two more hard cardboard boxes. The main black box is covered by a transparent plastic cover which also holds the Hybrid Silent-Pipe 2 cooler into place. When the cover is removed, the motherboard is fully visible. The reason why the box has some volume to it is because the inside of the box is filled with soft foam to prevent any damage to the motherboard when it is shipped. A USB 3.0 sticker is put on the PCI-Express slots that needs to be removed when before the motherboard is installed.

This is the second cardboard box we have talked about. This is the accessories box where you will find everything from the User’s Manual, to the Driver CD and cables that you might need for proper installation. I like this way of packaging the accessories much better than how other companies do it. Others just throw all the accessories together with the motherboard or they will have a cardboard dividing the accessories and the motherboard. But the problem with that is that once you take out the cardboard that all the accessories are on, and you want to repackage the motherboard at a later time it is difficult to keep everything nicely together and also make sure the box closes easily. With GIGABYTE’s boxing, it is very easy to get to the accessories and it also keeps the manual, and cables separate from each other.

The 3 pictures above show the Hybrid Silent-Pipe 2 heatsink. This is a nice addition to the UD7 that did not come with the UD5 or the UD3R. The Hybrid Silent-Pipe 2 solution is only available on the UD7 and UD9 motherboards. On the first picture is the base of the heatsink, from which two heatpipes extend. The X58A-UD7 motherboard’s North Bridge heatsink is designed in a way that allows users to attach the heatpipes to a stock cooler. GIGABYTE also includes thermal paste to attach the heatsink completely. This system helps increase the cooling power of the Northbridge and other components like the MOSFETs and South Bridge, because all of them are connected together through a heatpipe cooling solution. The Hybrid Silent-Pipe 2 North Bridge cooler also needs to attach to one of the expansion slots in the case. This allows the heat to be more easily exhausted out the back through the expansion slot. The problem with this cooler is that there is no fan to blow over this area, and it is difficult to let the hot air go out through the narrow slot if there are only a few fins extending from the back. There needs to be some form of air pressure inside the system to push air out through the expansion slots to fully take advantage of this cooling solution. Also, from our tests even when the temperatures get really high, the heat does not transfer as well to the second heatsink, which means that the first heatsink group dissipates most of the heat.

Click Image For a Larger One
Along with the Hybrid Silent-Pipe 2 heatsink, GIGABYTE also included a water block that can be replaced by the North Bridge cooler currently installed. The whole heatsink does not have to be removed, only the area where the waterblock gets installed. So after the waterblock is installed, the water cooling loop will cool down the MOSFETs as well as the South Bridge even though the water block is mounted onto the North Bridge. The tubes required for this water cooling setup are 3/8″ tubing. The only problem we see here is that if the user is connecting their CPU and NB into one loop, their water cooling loop will most likely have to use 3/8″ tubing. In case users want to use 1/2″ tubing, they will be required to install reducers from 1/2″ to 3/8″ to connect to this waterblock. It would have been nice if GIGABYTE had designed the waterblock originally with a 1/2″ tubing instead, however. In the second picture we see that the waterblock has a near-perfect mirror finish. The performance of this waterblock should be quite nice, but we won’t be able to test it in this review as our water cooling loop recently developed a leak.

Here we see the included screws and thermal paste required for the installation of the Hybrid Silent-Pipe 2 heatsink. Though GIGABYTE provides us with a generic thermal paste, we still prefer to use a branded compound, such as the Arctic Silver Ceramique (the Ceramique is almost as good as Arctic Silver 5 but it is non-conductive, eliminating the risk of burning out hardware. The provided generic compound should also be non-conductive. Next up we have the User Manual, an Installation guide, and an application guide. Also included are a Driver CD and a GIGABYTE and Dolby Home Theatre sticker. We accidentally left the Dolby sticker in the User’s Manual because at first we did not know it included.

Finally, here are all the accessories that were included in the accessory box:

  • IDE Cable
  • Floppy Cable
  • 4 SATA Cables
  • 2-port eSATA PCI Expansion Bracket (with accompanying eSATA cables)
  • 2-Way SLI bridge connector
  • 3-Way SLI bridge connector
  • I/O Panel


The Motherboard from all angles

Interestingly, when we removed the motherboard from its packaging, the anti-static bag that most motherboards come in was absent. Though the anti-static packaging makes it difficult to see a motherboard from the outside of the box even through a window, we would have preferred it if the motherboard arrived in one of them. The first few things we notice about the GA-X58A-UD7 is that it uses a very nice baby blue and white color scheme. The overall cooler design and and the Ultra Durable 3 on the South Bridge make this motherboard look nice in systems with a side window.
There are 7 expansion slots on this motherboard. The first two PCI-Express slots are x1 slots, followed by a PCI-E x16 slot, a PCI-E x8 slot, a second PCI-E x16, an old PCI x1 slot, and a second PCI-Express x8 slot. The 1st and 3rd PCI-Express 2.0 slots are 16x, while the 2nd and 4th PCI-Express slots are x8. This was well thought out, as most users will use SLI in the 1st and 3rd PCI-Express 2.0 slots due to extra performance. However, for those who want some space between their cards to lower temperatures on the first GPU, the last PCI-Express x8 slot can only be used with single expansion slot cards, unless the user uses a case that has more than 7 expansion slots. We would also like to mention that when the Hybrid Silent-Pipe 2 cooling solution is added to the motherboard, the first two PCI-Express x1 slots become unavailable. It is also important to plug in any audio cable before installing the Hybrid Silent-Pipe 2 cooler because the clearance area under the cooler will be very small.

To more easily understand how the motherboard is laid out, we have superimposed a diagram onto a picture of the actual motherboard. We also included the motherboard block diagram to help readers understand what each of the chips and components on the motherboard are designed to do. Starting with the first picture, we notice that GIGABYTE put some of the components on the back of the motherboard’s PCB. Some of these components are designed to increase system stability when it is overclocked and under full load. They also help with designing the motherboard and organizing the components. Overall the placement for all of the components including the connectors is well organized. It is good to see that GIGABYTE places all of their power connectors including the 8-pin and 24-pin on the edges of the motherboard. The Floppy, IDE, and SATA connectors can also be found on the edges of the motherboard. This makes it very easy to route the cables around the motherboard, and also helps with air circulation because the cables will not block air flow. However, we would have liked to see the Front Audio connector on the bottom of the motherboard somewhere next to the USB and Firewire connectors. This would have made cable routing easier. Due to the Front Audio cable’s proximity to the North Bridge, users only have two options to route cables: either over the motherboard (which would hamper air circulation) or under it. While this is possible on some cases, on others it might not be, which is why it would have been nicer to see the audio connector on the bottom of the motherboard where the cables can easily be routed.
Other than that, it is clearly visible that there is no difference on the expansion slot design between the X58A-UD3R, X58A-UD5 and X58A-UD7 motherboards. It is a bit disappointing that a motherboard about $130 more expensive than the X58A-UD3R still uses the same expansion slot design. It would have been nice to see 4-Way SLI and CrossFireX compatibility on the UD7, because most people will not want to spend $700 on the UD9 just for that one feature. They will most likely go with another brand that offers the 4-Way SLI or CrossfireX feature on a board that is in the UD7’s price range. If the North Bridge cooler had been designed a bit differently, there would have been space for the extra PCI-Express x16 or x8 slot where the first PCI-E x1 slot is located.

Finally, from the picture which shows the front of the motherboard, we can see that there are a total of 4 system fan connectors, two of which are PWM fan connectors. There is also one more fan connector right next to the North Bridge cooler.

Though it is not quite visible on any of these pictures, GIGABYTE states that their PCBs are built with a double copper layer for lower temperatures, better overclocking, better power efficiency, 2x lower impedance, lower EMI and better ESD protection. While it is nice of GIGABYTE to include this, there is no 100% way of really testing these features just with benchmarks. Nonetheless, we are going to test for temperatures, energy efficiency, and for overclocking and see how far we can go.

Let’s take a closer look at what the X58A-UD7 has to offer. Starting off with the bottom right corner of the motherboard, we can see three Front USB header connectors, but it is important to note that only the USB ports routed to the white USB header can support the ON/OFF Charge function for charging mobile devices. We can also see a hidden IEEE 1394a Firewire header between the last PCI-Express x8 slot and the PCI x1 slot. The front panel header includes all the necessary connections for the Power Switch, Power LED, Reset Button, Hard Drive Activity LED, Chassis Intrusion Header and Speaker. This is located right at the bottom right corner of the motherboard for easy access. Right above the white USB and front panel header, we can see an IDE connector for those still using IDE devices. The IDE channel is controlled by the GIGABYTE SATA2 chip located right next to the IDE connector. The reason for this is because the Intel ICH10R chipset no longer supports IDE (the older ICH9R did). In between the IDE connector and the SATA connectors, we see the Debug LEDs which helps with booting problems. When a problem is present the motherboard will most likely stop at an error code. This code can be looked up in the X58A-UD7 motherboard manual for clarifying where the problem might be. Then we have the 90 degree SATA connectors. We like the 90 degree angle of these connectors. The 6 blue SATA 2 connectors and the two white SATA connectors on the far left side are controlled by the ICH10R chipset, while the two white SATA connectors close to the middle are SATA 3 connectors controlled by the Marvell 9128 chip. The 6 blue SATA 2 connectors support RAID 0/1/5/10 setups, while the SATA 6Gb/s capable connectors only support RAID 0/1 as there are only two of these connectors.

On the second picture we can see one of the system 3-pin fan headers on the far left side. Right next to it to the right, we see the 24-pin power connector and 3 phase power for the memory slots. These help make sure that the voltages on the memory modules are as stable as possible. The memory slots are quite close to the CPU socket though, those who wish to install CPU coolers like the Thermalright TRUE Black 120 or the Noctua NH-U12P should be aware that tall memory modules will not fit. It is possible to turn the CPU cooler around by 90 degrees, but some tower CPU coolers will not fit that way either due to the North Bridge cooler. Lastly, we see a power switch, a reset switch and several LEDs right next to the Power switch to show how high the BCLK is raised in the BIOS. The more LEDs that light up, the higher the BCLK is set to.

Continuing around the motherboard, we come across the PWM fan connector that the Intel stock cooler will use. We can also see the CPU socket and 9 out of the 16 Ferrite Core Chokes that regulate the power for stable voltages for overclocking. We can also see that the heatpipe solution for the MOSFETs on the UD7 is much more developed than the setup on the UD3R. This is excellent because the X58A-UD7 is designed to be overclocked to high voltages and withstand excessive heat. We can also see the 8-pin CPU power connector. The extra space around this connector is a definite plus, because the GA-MA790FXT-UD5P motherboard had a terrible design around the 8-pin connector. The problem with that board was that the MOSFET cooler was too close to the connector, making it very difficult to plug in the 8-pin power connector if a tower cooler was installed on the CPU and the motherboard installed in the case. Thankfully, this is not a problem with the X58A-UD7 motherboard.

The back left side of the motherboard has all connectors that will be visible on the back of the case: the PS/2 Keyboard and Mouse Ports, the Optical S/PDIF Out connector that provides digital audio out to an external audio system that supports digital optical audio. Below the Optical S/PDIF, GIGABYTE also included a Coaxial S/PDIF Out Connector which is essentially an Optical S/PDIF except for Coaxial audio devices. Following, we have a very handy “Clear CMOS” button, which allows us to clear the CMOS in case overclocking goes into unstable areas and the system will not boot. Then we have two firewire IEEE 1394a ports, two USB 2.0/1.1 ports, and two eSATA/USB combo connectors. It is very interesting that we see the support for both either USB or eSATA. This saves space and users can use the connectors for USB when eSATA is not being used. Subsequently, we also have two more USB 2.0/1.1 ports, two RJ-45 LAN ports that are capable of up to 1Gbps data rate, two USB 3.0 ports that are 10x faster than the previous USB 2.0 ports, and standard audio input and output jacks. We would also like to add that it would have been nice to have a dedicated sound card instead of an onboard audio codec due to the fact that this motherboard is more expensive than the UD5 with only minor changes. After testing the audio output power of the onboard audio connector, we found that an old Dell Inspiron e1405 laptop could produce the same amount of volume at 20% setting as the UD7’s onboard bus could at 100%. The audio performance is insignificant with large speakers that use external power adapters, but for large headphones that require more power, it could be a problem.

If we take a look between the PCI-Express x16 and x8 slots, visible on the 6th picture on this page, we can see several rectangular switches that split the 32 PCI-E 2.0 lanes between the four PCI-E slots we see on this motherboard. This means that when users are operating two video cards in the 1st and 3rd PCI-Express x16 slots, both slots will get x16 performance (x16/x16), but in a 3-way SLI or CrossfireX configuration, the 1st PCI-Express slot will stay x16, and the 3rd and fourth will become x8 (x16/x8/x8).

On the same pictures, we can also see the iTE IT8720F chip, which is responsible for the floppy connector and the PS/2 Keyboard and Mouse connectors. A bit higher up by the F_AUDIO connector, there are two Realtek RTL8111E chips that take care of the two 1Gbit LAN connectors. In between the Realtek and iTE chips, there is one more chip which is responsible for the audio codec used on this motherboard. Then on the second picture, the two BIOS chips are clearly visible. In case one BIOS chip gets damaged, the second one takes over. Lastly, we can also see the Floppy connector and two more fan connectors. One of them is a 3-pin fan header while the other one is a 4-pin PWM fan header.

Below the heatpipes of the North Bridge cooler, a small heatsink is visible. This heatsink cools the NEC D720200F1 chip, which controls the 2x USB 3.0/2.0 ports where the I/O connectors are located. If we take a look at the North Bridge cooler, we can see the vertical cutout holes where the Hybrid Silent-Pipe 2 North Bridge cooler is attached. It’s essentially the same process as installing a CPU cooler on to the Processor itself, except this time the thermal paste is spread inside the vertical lines and on top of the smooth surface, because the heatpipes will connect in those vertical cutouts (thermal paste is required to ensure good contact between the Hybrid Silent-Pipe 2 cooler and the stock North Bridge cooler).

The second picture reveals the pins for the Socket LGA 1366. We can see that GIGABYTE also decided to use Japanese Solid Capacitors, which run cooler and work for longer than the older capacitors.

When we first looked at the motherboard and noticed that GIGABYTE changed their motherboard design from 24 Phase Power to 16 Phase Power, we were very disappointed. The older X58A-UD7 Rev 1.0 still comes with 24 Ferrite Core Chokes while the Rev 2.0 only comes with 16 Ferrite Core Chokes, the same amount as the UD5. For the distinctly diminished number of core chokes, however, GIGABYTE only decreased the price by $50. The largest difference between the UD5 and the UD7 is the Hybrid Silent-Pipe 2 cooler. The X58A-UD9 is now the only motherboard that comes with 24 Phase Power in the new revision series. It would have been nice for GIGABYTE to provide at least 20 Phase Power for the UD7, to bring out the difference between the UD5 and the UD7 a bit more. This picture also shows the Intel Core i7 920 processor installed into the socket.

Finally, these last two pictures show the way a partially complete system would look with 3-Way and 2-Way CrossFireX or SLI configuration. Usually, in a 2-Way SLI setup, the cards would be right next to each other on this motherboard, so there would be no gap between the two video cards. That would also perform faster due to the video cards taking advantage of both x16 slots. 3-Way SLI or CrossFireX configuration gives x16/x8/x8 speeds. For cases with only 7 expansion slots, the 3-Way configuration would work without problems if the video cards are slim and only occupy 1 expansion slot.

Users will most likely be presented with GIGABYTE’s Full Screen Logo boot screen when they first turn on their systems. We have turned off that feature just to see exactly what hardware the motherboard recognized, and to to show the conditions of the BIOS prior to overclocking. When the full screen logo is disabled, the black screen shown above will show up along with the IDE/SATA drives that are recognized. If there was a problem with previous overclocking settings, the BIOS will also warn users.

Though GIGABYTE uses an older style BIOS, the true quality of a BIOS is determined by the ease with which a user can navigate it. It wasn’t too hard to get used to the new look, and after playing with it for 15-20 minutes, we already knew where to find everything. Regular overclockers and who like to mess with their computers should find this BIOS very enjoyable to work with. Starting off with the basics, the first image shows the main BIOS page. The F9 button shows all current system specs. The third picture shows the MB Intelligent Tweaker (M.I.T). This section shows all the main motherboard settings, as well as some PC health information such as fan speeds, temperates, and voltages.

The first section in the MB Intelligent Tweaker (M.I.T) is the M.I.T Current Status. In this section users can check on the current status of their hardware, including whether it is overclocked or at the stock settings, how many memory modules are installed and how they are detected, and the timings timings for each memory module. The next section is the Advanced Frequency Settings section. This section allows users to control CPU clock speeds, timings, and QPI. Users also have full control of the PCI Express Frequency and some other tweaks for the processor. There is also partial Memory overclocking present here, with the ability to change the System Memory Multiplier. However, this setting also determines how well the processor can be overclocked. Within the Advanced Frequency Settings are the Advanced CPU Core Features, containing different feature settings for the processor. The features can differ by processor. For our settings, we went ahead and disabled CPU Thermal Monitor which was originally enabled. Within this section users can also set the number of processors cores they want to use. Interestingly, while some applications already work with processors that have multiple cores, some applications might not. A good example would be an older game that does not support multiple cores. If users were to disable two cores on the processor and decide to overclock it to a higher clock speed, the heat production would decrease. In cases such as these, users wouldn’t need a very powerful cooling system to achieve high clock speeds that games can perform well at.

The following pictures still show the Advanced Frequency Settings section of the GIGABYTE GA-X58A-UD7 Rev 2.0 motherboard. In the first picture, the QPI clock ratio is set. The x36 gives a QPI link speed of 4.8GHz while the x48 gives a QPI link speed of 6.4GHz. As the BCLK Frequency controls the CPU Frequency and Memory, the QPI link speed will also change when the BCLK is changed. This is also true of the Uncore Frequency, which can also be changed by the Uncore Clock Ratio. Finally, the last picture shows the System Memory Multiplier (SPD) which controls what frequency the memory runs at. For example if our BCLK Frequency is set to 200MHz, that’s 200MHz x 6.0 = 1200MHz. If we set the System Memory Multiplier (SPD) to 18.0, that will give us a memory speed of 3600MHz for the memory. At the moment, no manufacturer supports memory speeds that high for DDR3 System Memory, but this just shows us the potential this motherboard has.

Next up is the Advanced Memory Settings section where all the memory settings are applied. On the first picture we can see the same System Memory Multiplier (SPD) that we have seen in the Advanced Frequency Settings section. If the DRAM Timing Selectable (SPD) is set to Standard mode, all the timings will be automatically set on the memory. If it is set to Quick mode, you can change the timings on one channel and it will change all the memory timings to your preferred timings. But here is the interesting part. Lets say you have two different memory modules from two different manufactorers. One of the memory kits might have different timings. GIGABYTE also gave the end-user the option to change the DRAM Timing Selecatable (SPD) to Expert mode, which allows the user to set the timings on each channel.

The following three pictuers show the Advanced Voltage Settings panel and the Miscellaneous Settings panel. The Advanced Voltage Settings panel enables the user to change the voltages on just about any part of their system. For overclocking purposes, we only had to alter the CPU Vcore, QPI/VTT Voltages, CPU PLL, QPI PLL and IOH Core and DRAM Voltages. While this might be scary for some, GIGABYTE does color code their voltage settings to make it easier for the user to know which settings are dangerous when tampered with. Users still unsure of their expertise should keep the settings on AUTO. For the more advanced users, this will probably not be an issue, but caution is always recommended.

This is the Standard CMOS Features section, which dectects HDDs and input drives. If RAID is enabled in the BIOS, the list of IDE Channels will be lowered drastically, which is why we cannot see any of the hard drives present here. Those hard drives are controlled by the Intel Matrix Storage Manager which we will examine later in this page. The second picture shows the Advanced BIOS Features page, which includes some important boot settings. The third picture shows the Hard Disk Boot Priority section.

The Integrated Peripherals section is probably the longest section of the BIOS. Here, users can enable and disable functions on the BIOS. If the extra IDE and LAN functions in the BIOS are disabled, the system takes less time to boot. To save time, we have disabled as many of the unnecessary functions as we could. The Power Management Setup section gives users the option to tinker with the way the computer powers up or goes to sleep. This section also enables Keyboard and Mouse booting as well as enables the system to be rebooted in case of a power outage.

Lastly, the PC Health Status section shows all important information about fan speeds, temperatures, voltages, and gives extra options for temperature and fan settings. The last picture is the Intel Matrix Storage Manager which enables users to set up hard drives in a RAID 0/1/5/10 configurations. In this picture a RAID 0 configuration is already set up with two Western Digital RAID Edition 3 hard drives.

First Boot – Intel Core i7 920 C0

After setting up the UD7 in a Silverstone Temjin TJ10 chassis and loading the necessary hardware, including a Core i7 920 C0 revision CPU, OCZ 6x2GB 12GB DDR3-12800 1600MHz memory modules, and two new Palit GTX460 Sonic Platinum video cards in SLI, we booted up the system. We noticed right away that the memory modules were recognized and were automatically set to run at 1066MHz. Examination of the BIOS showed that the System Memory Multiplier was set to 8x (that’s 8 x 133 = 1064MHz). We increased the multiplier to 12x, so the memory modules would run at the stock 1600Mhz frequency. We also made sure the DRAM Voltage was set to 1.64V and timings were set to stock settings at 8-8-8-24 2T. When we restarted the system, we got a blank screen. After careful investigation, we realized that when our last motherboard had fried, it had also damaged the CPU. We tried loosening the timings a bit to 9-9-9-30, but the system still did not boot at 1.65V. After receiving a new Core i7 930 in the mail, we installed it right away, and the system successfully booted up at 1600MHz at the correct timings and voltage. We also switched out the OCZ memory modules to a Kingston 2133MHz DDR3 Dual-Channel 4GB kit to see how the motherboard would react to those modules. The memory was recognized, but only at 1066Mhz, and after tweaking the BIOS we easily booted at 2000Mhz. However, reaching 2133MHz with the Core i7 930 was still difficult. It is important to understand that most of the time the limitation is not in the motherboard, but in the memory controller on the CPU. It takes a very powerful CPU (Extreme, Unlocked) to achieve stability at 2133MHz on such motherboards.

Overclocking with the UD7 – Core i7 920 C0

When the first booting problem started with the OCZ memory, we wondered how the system would handle overclocking, but it ended up being a very enjoyable process. On the old ASUS P6T motherboard, when we set the BCLK to 180 and the CPU Clock Ratio to 20x, we still had to adjust voltages for a stable boot. Since GIGABYTE is well known both for overclocking to high clock speeds and for setting world records, we wondered how well it would run if we kept all the voltages at AUTO. This also puts GIGABYTE’s Ultra Durable 3 motherboard design to the test, because they state that their motherboards are more stable than traditional motherboards due to the double copper layer they use in their PCB. We saved the settings and restarted the system after setting the BCLK to 180 and CPU Clock Ratio to 20x. There was no problem with booting and the voltages were automatically set. Now we were running 3.6Ghz at 1.38V, and when Windows 7 booted up, we ran LinX for several hours to confirm that everything was stable. There were no errors, but the core temperatures on the processor were hitting 91C, along with the motherboard at 60C.

We would like to mention that we are running a quiet system with lower air circulation than an average overclocked gaming system. The case does not come with any side ventilation, only one 120mm front intake fan, and two 120mm outtake fans on the top and one 120mm outtake fan on the back. We also have installed the Thermaltake TRUE Black 120 CPU cooler and two Noctua NF-P12 120mm quiet fans. Also, this Core i7 920 is a C0 revision which tends to run hotter then the newer D0 revision due to higher voltages required for overclocks.

We were still not satisfied with the overclocked processor and the temperatures we were getting. We started overclocking manually by first finding the maximum BCLK that the motherboard could run at. To do that, we set the CPU multiplier to 12x so as not to stress the processor too much. We also found the lowest voltages that were stable: 0.9V on the 920 C0. After slowly raising the BCLK and the CPU, QPI, VTT, and NB voltages, we finally found the limit at 213MHz (the system would not boot at 214MHz even when the motherboard voltages were raised into the red zones). We ensured plenty of air circulation through the system by using a large house fan to blow air into the computer. This limited the risk of component blowouts due to overvolting.

When we found the maximum BCLK on the UD7, we lowered it to 200MHz to make relieve stress on the motherboard. We then gradually increased the multiplier from 12x to 18x. We were curious to see whether we could reach the same 3.6GHz speeds without having to use 1.38V for the VCore. As we believed, this worked, and we achieved 3.6GHZ stably at 1.2875V in the BIOS (CPU-Z showed this as 1.248V). That is impressive, because we could not get the Core i7 920 stable at 1.2875V on the ASUS P6T motherboard. The lowest we could go on that motherboard was around 1.35V in CPU-Z. That’s a 0.1V difference between the two motherboards.

We were very impressed with GIGABYTE’s overclocking performance when it came to the processor. Interestingly, the memory on the motherboard would not run at higher speeds than 1440MHz when the processor was overclocked (Damaged Memory Controller on the Core i7 920 C0). As an 8x multiplier on the motherboard started hitting high speeds on the memory, we were forced to reduce the multiplier to 6x to keep the memory stable at 1200MHz. So that’s 6×200=1200MHz. I could however lower the timings to 7-7-7-18. The temperatures on the processor were a lot better. With at lower voltage required to run the processor in stable condition, the temperatures dropped to 80C max on Core 0. This is about a 10-12C difference from the AUTO settings that the GIGABYTE board set the voltages to when the processor was running at 20 x 180MHz. 

We continued pushing the motherboard and processor further. The next overclock that we managed was at 3.74GHz. We will use this to benchmark this motherboard against the ASUS Maximus 3 motherboard with a Core i5 processor overclocked to 3.74GHz. To make things more accurate, because our Core i7 920 C0 revision cannot run at speeds higher than 1440MHz, we will be using our new Core i7 930 D0 revision CPU to clock the memory at close to 1600Mhz and 3.74GHz on the processor. The processor required 1.35V at 3.74GHz, and the voltages seemed to jump up quite high from there on. We pushed it even further and was able to achieve 4.2GHZ at 1.424V according to CPU-Z and 4.3GHz at 1.536-1.520V.

We were once again very impressed because we could not get through the 4.2GHz barrier with the ASUS P6T motherboard, but we could with the GA-X58A-UD7 Rev 2.0 motherboard.

Overclocking with the Core i7 930 D0

We will not go into too much detail about the Core i7 930, because we followed the same process for overclocking that we did with the Core i7 920 C0. We did however set my memory frequency to 1600Mhz with an 8x multiplier on the memory. The pictures below show several overclocked settings that were completely stable, and how we managed to get really low voltages, decent temperatures, and high clock speeds with a quiet system running on air.

In the first picture, we were looking for the lowest voltage we could use on a stock CPU. We managed to go down to 0.944V and run completely stable even after 3 hours and 15 minutes.

Click Image For a Larger One

In this picture, we got up to 3.6GHz by setting the Base Clock (BCLK) to 200MHz and the multiplier to 18x. The voltages on the 930 D0 revision CPU were about 0.064V lower than on the Core i7 920 C0 processor. This resulted in a temperatures about 4 degrees on Core #0.

Click Image For a Larger One

Finally, we wanted a setting for our system that we could use for everyday purposes, so we settled at around 3.8GHz, because going to 4.0GHz required an increase of 0.1V on the VCore, and our air cooling would not be sufficient to cool the CPU. At 3.8GHz, our voltages were at 1.232V, which is still lower than what we got with the Core i7 920 at 3.6GHz. This also means that our temperatures with the Core i7 930 D0 running at 3.8GHz (1600Mhz Memory) and 1.232V were about 2 degrees Celsius lower than on the Core i7 920 C0 running at 3.6GHz (1200Mhz Memory) and at 1.248V. The LinX stress test on the CPU and Memory proves that the system was still running stable after the 9 hour 27minute stress test.

Different Overclocked settings that were 100% stable:

Click Image For a Larger One

We can see that speeds higher than 3.8GHz require a huge increase in voltage for stability. This is the point where the CPU Frequency-to-Voltage ratio starts taking the shape of an exponential graph. From this data, we can infer that increasing from 4.0GHz to 4.2GHz will need an even higher increase.

Testing & Methodology

We’ve expanded our testing suite considerably for the X58 chipset, and will continue to use the same methods for most of the motherboards and CPU’s we test. In the interests of thoroughness and accurate results, we run each test at least three times, and some tests more than that. We average the total of all the tests from each benchmark then report the average here.

The OS we use is Windows 7 Pro 64bit with all patches and updates applied. We also use the latest drivers available for the motherboard and any devices attached to the computer. We do not disable background tasks or tweak the OS or system in any way. We turn off drive indexing and daily defragging. We also turn off Prefetch and Superfetch. This is not an attempt to produce bigger benchmark numbers. Drive indexing and defragging can interfere with testing and produce confusing numbers. If a test were to be run while a drive was being indexed or defragged, and then the same test was later run when these processes were off, the two results would be contradictory and erroneous. As we cannot control when defragging and indexing occur precisely enough to guarantee that they won’t interfere with testing, we opt to disable the features entirely.

Prefetch tries to predict what users will load the next time they boot the machine by caching the relevant files and storing them for later use. We want to learn how the program runs without any of the files being cached, and we disable it so that each test run we do not have to clear pre-fetch to get accurate numbers. Lastly we disable Superfetch. Superfetch loads often-used programs into the memory. It is one of the reasons that Windows Vista occupies so much memory. Vista fills the memory in an attempt to predict what users will load. Having one test run with files cached, and another test run with the files un-cached would result in inaccurate numbers. Again, since we can’t control its timings so precisely, it we turn it off. Because these four features can potentially interfere with benchmarking, and and are out of our control, we disable them. We do not disable anything else.

We will use the following applications to test the performance of the motherboard. Benchmarks

Excel 2007
SiSoft SANDRA 2010
Everest Ultimate Edition
Cinebench R10 64-bit
3DMark Vantage
WinRar v.3.80
Pro Show Gold 4.1

Heaven Benchmark

After the aforementioned tests, we will also dedicate a page to testing USB 3.0 benchmarks. Using several hard drive benchmarking applications, we will see how high our maximum benchmark score is with a RAID0 hard drive setup through USB 3.0. We’ll compare the results to USB 2.0 to see what the actual speed difference is between the two.

Everest Ultimate

“EVEREST Ultimate Edition is an industry leading system diagnostics and benchmarking solution for enthusiasts PC users, based on the award-winning EVEREST Technology. During system optimizations and tweaking it provides essential system and overclock information, advanced hardware monitoring and diagnostics capabilities to check the effects of the applied settings. CPU, FPU and memory benchmarks are available to measure the actual system performance and compare it to previous states or other systems. Furthermore, complete software, operating system and security information makes EVEREST Ultimate Edition a comprehensive system diagnostics tool that offers a total of 100 pages of information about your PC.”

Each of these CPU test are a bit different from each other. For example while one of them performs mathematical calculations, the other might perform photo related calculations, including turning photos, resizing, etc. As many of our readers know, the ASUS Maximus 3 Extreme motherboard is actually a LGA 1156 motherboard with Dual-Channel Memory slots. The ASUS P6T and the GIGABYTE GA-X58A-UD7 motherboards are LGA 1366 and Triple-Channel motherboards. Interestingly we noticed a pattern in some of these tests. For example the CPU PhotoWorxx, while the processors were actually clocked at the same speed and had the same amount of cores and threads, the triple channel motherboards had advantage over the dual-channel motherboard in this benchmark. The performance between the P6T and the UD7 were almost identical, but the UD7 still managed to be in the #1 spot in most tests.

Everest Ultimate Memory Suite

In the memory performance benchmark, the UD7 dominated the write speed test in the overclocked settings while the P6T and the Maximus 3 Extreme dominated the other tests.

When we ran the previous memory performance tests, the UD7 did not do so good compared to the other motherboards, so we were wondering how the UD7 will perform in the latency benchmark. We see similar results here, where the UD7 was only been able to perform only by 0.1ms faster on the stock settings.

Sisoft Sandra 2010

“SiSoftware Sandra (the System Analyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software. It works along the lines of other Windows utilities, however it tries to go beyond them and show you more of what’s really going on. Giving the user the ability to draw comparisons at both a high and low-level. You can get information about the CPU, chipset, video adapter, ports, printers, sound card, memory, network, Windows internals, AGP, PCI, PCI-X, PCIe (PCI Express), database, USB, USB2, 1394/Firewire, etc.”

The SiSoft Sandra Arithmetic benchmark performs several different arithmetic calculations to determine performance on the CPU. In the Drhystone benchmark, the UD7 was able to pull forward in front of the other two motherboards, while in the Whetstone benchmark, the UD7 was able to beat the P6T (X58 chipsets), while it lost to the Maximus 3 Extreme (P55).

On the SiSoft Sandra Memory benchmark, we saw the same results as we have seen on the Everest memory benchmark. The UD7 fell short on the memory benchmarks compared to the other motherboards, especially when the CPUs were overclocked.

I’m quite pleased with the following results on the MultiMedia benchmark. While I work a lot with multimedia, it is good to know that the UD7 performed far better on multimedia than the other motherboards.

Cinebench R. 10.5

“CINEBENCH is a real-world test suite that assesses your computer’s performance capabilities. MAXON CINEBENCH is based on MAXON’s award-winning animation software, CINEMA 4D, which is used extensively by studios and production houses worldwide for 3D content creation. MAXON software has been used in blockbuster movies such as Spider-Man, Star Wars, The Chronicles of Narnia and many more. MAXON CINEBENCH runs several tests on your computer to measure the performance of the main processor and the graphics card under real world circumstances. The benchmark application makes use of up to 16 CPU’s or CPU cores and is available for Windows (32-bit and 64-Bit) and Macintosh (PPC and Intel-based). The resulting values among different operating systems are 100% comparable and therefore very useful with regard to purchasing decision-making. It can also be used as a marketing tool for hardware vendors or simply to compare hardware among colleagues or friends.”

Cinebench R10, which requires multi threaded 3D rendering proved that the UD7 might just not be as scalable in multi threaded applications like Cinema 4D as the other motherboards. The ASUS Maximus 3 Extreme showed quite a bit of performance increase in the CPU speed even when the frequencies were at the same settings. This performance increase will only have about 1 second difference in 3D rendering over the UD7 and the P6T. The rendering difference would only be clearly visible if a full 3D animation would be rendered that requires several hundred frames to be rendered. After each 60 frames, you would grant at least 1 minute in rendering speed. So at 600 frames you would see a 10 minute difference between the different motherboards, and at 6000 frames, a 100 minute difference, which is 1 hour and 40 minute difference. However, rendering 6000 frames would take about 3 days to render if the scene does not change significantly, so that extra 1 hour and 40 minutes is not too much, unless you are on a strict timeframe.

POV-Ray 3.7 Beta 28

The Persistence of Vision Ray-Tracer was developed from DKBTrace 2.12 (written by David K. Buck and Aaron A. Collins) by a bunch of people (called the POV-Team) in their spare time. It is a high-quality, totally free tool for creating stunning three-dimensional graphics. It is available in official versions for Windows, Mac OS/Mac OS X and i86 Linux. The POV-Ray package includes detailed instructions on using the ray-tracer and creating scenes. Many stunning scenes are included with POV-Ray so you can start creating images immediately when you get the package. These scenes can be modified so you do not have to start from scratch. In addition to the pre-defined scenes, a large library of pre-defined shapes and materials is provided. You can include these shapes and materials in your own scenes by just including the library file name at the top of your scene file, and by using the shape or material name in your scene. Since this is free software feel free to download this version and try it out on your own.

POV-Ray puts the same 3D rendering test into action as Cinebench R10 did, however, in this test, the actual rendering performance was exactly the opposite from Cinebench. The UD7 actually performed the best, and took the shortest amount of time to render the scene. We do not really have a 100% explanation why this happened.

WinRar v. 3.80

This module in WinRar generates random data, which contains specially introduced redundancy, increasing the load to both the processor and memory. Data is then passed through RAR compression and decompression algorithms, and the output of the decompression algorithm is compared to the source data. If any differences are found, WinRar then reports “Errors found – Yes” in the command window. WinRar displays a size of processed data and compression speed, current and resulting, in kilobytes per second.

Since WinRAR also depends on the write speed of the hard drives, it is not a perfect test if different computers are tested for results, however since we are using the same hardware on each of our motherboards, we can be safe on not having skewed results. The UD7 showed a big performance increase in archiving 5 large TIFF images at stock settings over the other motherboards, but once the CPU was overclocked, the results came quite close to each other, but the UD7 still managed to outperform the P6T and the Maximus 3 Extreme.


Blender is a free open source 3D content creation suite that is available for various operating systems. The application is popular among many independent animation studios and game makers. For more information, please visit

The workload consists of a ~6.9 MB character model of a flying squirrel. Due to time constraints we don’t render the entire image, as this would be time consuming and rather pointless (though the benchmark results would be larger, the ratios would stay the same). The squirrel’s right arm is large enough to show differences in CPU performance, yet small enough that we don’t have to waste 45 minutes of rendering on a single result.

Finally, in Blender, which is yet another 3D modeling and animating application, the rendering performance was quite similar to each other. From the tiny bit of performance increase the UD7 had, the performance should not be too drastic between the different motherboards even on larger project files.

Photodex ProShow Gold 3.2

ProShow Gold allows you to combine videos and photos and music to create slide shows, depending on the end user results can be spectacular. The application allows the end user to share photos and memories with friends in a unique and spectacular way, the different formats supported are, DVD, PC and Web. Still Photos are brought to life by adding motion effects. Supported effects include, Pan, Zoom, and rotate. You can also add captions and over 280 transition effects.

Photodex PROShow Gold is a bit different from the other rendering applications. Film editing applications usually take advantage of the memory, so memory speeds and sizes can change rendering speeds. The results were very close, and in most cases when we ran the benchmarks the results were identical to the other motherboards as well.

Microsoft Excel 2007

Monte Carlo Black-Scholes Option Pricing Test

Microsoft Excel is the widely known and most used spreadsheet application for the manipulation and calculation for number crunching. With Excel you can analyze and share information on small scale or the largest scale you can imagine. We’ve seen spreadsheets in every day use that contain literally tens of thousands of numbers and hundreds of equations. Bjorn3D uses two tests in Excel to determine CPU and Motherboard performance.

This workload calculates the European Put and Call option valuation for Black-Scholes option pricing using Monte Carlo simulation. It simulates the calculations performed when a spreadsheet with input parameters is updated and must recalculate the option valuation. In this scenario we execute approximately 300,000 iterations of Monte Carlo simulation. In addition, the workload uses Excel lookup functions to compare the put price from the model with the historical market price for 50,000 rows to understand the convergence. The input file is a 70.1 MB spreadsheet.


The Excel benchmark is a bit unrealistic in the sense that usually a person does not have thousands of lines of data that needs to be calculated. Even in such situation, the time difference between the motherboards is not too big which would lead to the user picking a different motherboard. We ended up sharing the results anyway. The UD7 had a clear performance boost over the other motherboards but we do not have a clear explanation why this might be the case.

3DMark Vantage


For complete information on 3DMark Vantage Please follow this Link:

The newest video benchmark from the gang at Futuremark. This utility is still a synthetic benchmark, but one that more closely reflects real world gaming performance. While it is not a perfect replacement for actual game benchmarks, it has its uses. We tested our cards at the ‘Performance’ setting.

Because we did not have an GPU/CPU combination test previously, 3DMark Vantage will be a perfect application to use to benchmark the performance between the motherboards. This benchmark showed that the scalability between the GPUs running in SLI is not really any different from the other motherboards. The scores are way to close to each other, so there is actually no real winner here, because the results could wary after each run by about 1% to 2%.

Unigine Heaven 2.1

Unigine Heaven is a benchmark program based on Unigine Corp’s latest engine, Unigine. The engine features DirectX 11, Hardware tessellation, DirectCompute, and Shader Model 5.0. All of these new technologies combined with the ability to run each card through the same exact test means this benchmark should be in our arsenal for a long time.

The performance difference on graphical benchmarks were minimal as well, with the UD7 performing the best in Stock settings while the Maximus 3 Extreme performing the best under Overclocked settings.

The following hard drive speed tests were tested through the USB 3.0 connectors on the GA-X58A-UD7 motherboard with the Ineo I-NA309D Pro USB 3.0 Dual-Bay RAID Enclosure. The performance on a RAID0 configuration should be enough to stress the USB 3.0 controller to see some high results.

We can clearly see that USB 3.0 has quite a bit of potential for future PCs. It will not be too long before we start seeing USB 3.0 devices in our everyday lives, and the old USB 2.0 devices will be the thing of the past. It is very interesting to see that the GIGABYTE GA-X58A-UD7 had no problem achieving same performance through the USB 3.0 interface as what we would have gotten through the internal SATA connectors on the motherboard. HDTach showed that the hard drives were able to reach up to 202.2MB/s burst speeds, along with a 133.2MB/s average transfer speed.

On the following 3 different benchmarks, there is not much to explain because the USB 3.0 performance is just astonishing. We just included two other hard drive setups through our USB 3.0 Dual-Bay hard drive enclosure to give an idea on how much performance is there to expect with different enclosures at different hard drive settings.

Real Life Testing

Copying 45 Video Files (20.2GB)

3min 9sec


5min 20sec


3min 47sec

USB 2.0 Single 12min 38sec

This performance comparison between USB 2.0 and USB 3.0 might be the actual benchmark that our readers will want to hear about the most. The difference between a Single USB 3.0 hard drive setup and a Single USB 2.0 hard drive setup is 8min and 49 seconds. This time difference is tremendous, considering that we were only copying 20.2GBs to the external enclosure. In case we would need to copy over 500GBs of files, the time saved over backing up the files could well be 1-3 hours over USB 2.0. Because there are SSDs and other faster solutions available now for USB 3.0, the performance could even be greater than what we have shown here.


We were not happy to see that GIGABYTE only put 16 Phase Power on the second revision of the GA-X58A-UD7 motherboard. The older first revision had a total of 24 Phase Power, so why did GIGABYTE change this? It seems when the UD9 came out, GIGABYTE wanted to keep the UD9 at the top of the market for overclocking performance, and have the UD7 as a runner up, with a better cooler setup than the UD5. However, improving the cooler design does not justify the price difference between the UD5 and the UD7. If GIGABYTE had left at least 20 Phase Power on the UD7, the price differences between the UD5, UD7, and the UD9 would have been fair.

The actual performance of the motherboard was great. While in some tests the UD7 dominated, in others the ASUS boards came out on top. However, the performance differences are only very slight, which means that the user will most likely never notice it. The real performance lies behind the overclockability of the motherboard and how it handles CPU overclocking. We noticed that on the GIGABYTE GA-X58A-UD7 Rev 2.0 motherboard, we were able to achieve the same overclock on our Intel Core i7 920 at 0.1V lower then on our ASUS P6T motherboard. This was very impressive. The auto overclocking capability between the two motherboards was quite similar, with the difference that the UD7 actually ran stably at 3.6GHz while the ASUS P6T motherboard was not 100% stable on AUTO settings.

The temperatures on the motherboard were not very different from the temperatures that we might have seen on other motherboards. We usually see the X58 chipsets running at around 38C idle, and at around 58C load. The GIGABYTE GA-X58A-UD7 motherboard with the Hybrid Silent-Pipe 2 solution actually ran at around 58C load, sometimes hitting around 60-62C when the room temperatures went up to around 28-30C. These temperatures were recorded under overclocked CPU settings at a 200 BCLK. We did not see any improvement in cooling, even with the inclusion of the Hybrid Silent-Pipe 2 solution. However, the motherboard stayed stable, even when we pushed it to critical voltages.

Through our testing, we can conclude that if the end-user does not require 4-Way SLI or CrossfireX support but still wants to coax as much out of their system as possible, the X58A-UD7 would be the best choice for a motherboard. Its definitely a perfect motherboard for enthusiast gamers, and overclockers. For those that don’t require the extra cooling, we would like to suggest the GA-X58A-UD5 motherboard, and for people that need decent overclocking features, and still have the USB 3.0 and SATA 3.0 features, the GA-X58A-UD3R would be a perfect solution.
