Gigabyte 890FXA-UD7

Gigabyte has comeup with the Ultimate gaming motherboard. Lets step inside and see why.


It has been a while since I played with a top end AMD CPU. Sure I’ve played with a few AMD CPUs here and there, but they were mainstream CPUs and not AMD top end counter parts. Even then, I was limited to what I could do because they were not my personal CPU. Well, my dad picked himself up an AMD 1055T Thuban six core CPU, and I happened to have one of Gigabyte’s flagship motherboard, the 890FXA-UD7.

The 890FXA-UD7 has four unique features that I personally like to see on a motherboard. One of these features is the use of SATA 3 (SATA 6 Gb/s), USB 3 and USB Power 3 (Gigabyte’s very own “333” design). This motherboard is one of the few motherboards that can fully support AMD/ATI’s four-way CrossfireX. You just have to make sure you have a large enough chassis. Because the 890FXA-UD7 is so huge, out of four different chassis I had floating around here, the only chassis that could remotely fit this motherboard was the Raven RV-02 from Silverstone (review can be found HERE). But even then, it was a tight fit.



Let’s get everything ready for a quick change out from my Intel Core i7 930 setup, to the Gigabyte 890FXA-UD7 AMD six core bad boy CPU. The only limitation that I was told by my father, was that I couldn’t go “Crazy” with his CPU.

We need to start somewhere, so let’s start on the packaging of the 890FXA-UD7. Like always, Gigabyte goes the extra mile to ensure us consumers know exactly what their products can do and what they come with. This motherboard also has Gigabyte’s very own “333” design capabilities. USB 3, SATA 3, and finally, USB power 3.

Opening up the top lid, we get a sneak look at the Gigabyte 890FXA-UD7 motherboard. After handling this box, you do get a feeling that this motherboard is simply huge.

This is what the 890FXA-UD7 motherboard looks like. You will have to wait and see what this monster really looks like when we do the overview portion of this review.

I truly like this style of packaging myself, where manufacturers separate the motherboard from the added extras by using separate compartments. This keeps things nice and tidy, and also ensures the motherboard will not be harmed during transporting.

What do we get with this motherboard? Well the answer is, we get a motherboard (well duh), an installation manual, a driver disc and finally another manual.

I had to separate what we received into two separate images, so continuing on, Gigabyte includes a USB/E-SATA rear I/O expansion port (this little expansion port allows us to use normal everyday SATA drives without needing an enclosure or docking station). Gigabyte also has a four pin molex that is connected to this rear IO expansion port. Gigabyte also includes a E-SATA to SATA adapter cable, a molex to SATA power connector. We get four light blue SATA cables, a rear I/O cover, an IDE ribbon and finally two ATI Crossfire bridges.


Now it is time for us to give you an idea on how the 890FXA-UD7 motherboard is laid out and what makes this motherboard unique. If you were like me and counted up all the expansion ports, and came up with 7 expansions, you are correct. Keep in mind that there is a silent pipe set up that has an additional expansion port, giving this motherboard a total of 8 PCI/PCI-e expansions; this motherboard is simply huge.

Moving our way to the where the SouthBridge and the SATA ports are located. It is not that much different from what we have seen on previous motherboards layout wise. In the upper right hand side we can see the heatsink that Gigabyte uses on the 850SB chip from AMD. Gigabyte does include a LED diagnostic numerical display right below the SATA ports, and it appears this board is about one inch longer than a standard ATX motherboard. Gigabyte includes six SATA 3 (SATA 6Gb/s, Blue) that are native to the SouthBridge. The two white SATA connectors are controlled by a third party chip. Then right above the white SATA connectors we can make out a clear CMOS button. This has a protective cover to make sure we don’t accidentally clear the CMOS.

Now let’s move to the PCI/PCI-E expansion ports. Gigabyte has 6 PCI-E VGA expansion ports along with a single PCI expansion port. The primary x16 PCI-E port is the uppermost PCI-E, the secondary full x16 PCI-E port is located right above the lonely PCI expansion port. For a true four way Crossfire X you will need to use the top most PCI-E x16 port, then you will need to skip a port and use the PCI-E x8_1 port, use the secondary full x16 PCI-E port, and then finally we need to populate the bottom PCI-E x8_2 port. By populating all PCI-E ports for four way CrossfireX reduces the bandwidth to x8 on all PCI-E ports.

Like all of Gigabyte’s high end motherboards, we can see the included water block that can be used to help keep the NB cool during heavy gaming/overclocking endeavors. I wish Gigabyte gave us the option of being able to switch out the barbs, because personally, I prefer 1/2” barbs for a higher flow than using the more restrictive 3/8” barbs.

Trying to see the clearance of the EPS CPU power plug; again this port is in a rather tight spot. It sits very close to the CPU power mosfets and has very little room from the power plug to the rear I/O ports. The heatsink that Gigabyte uses for the CPU power mosfets is a fairly large one, and it is directly connected to the NB heatsink by a heatpipe. This heatsink did get warm to the touch during my use of this motherboard, giving me the idea that this heatsink is doing its job and keeping the CPU power MOSFET’s cool and helping keep the NorthBridge cool as well.

Looking over the CPU socket area; it appears this area is fairly clear of large obstacles. What concerns me here is the clearance between the lower portion of the AMD CPU hold down plate and the NorthBridge heatsink. I did have a minor problem trying to install a Zalman 9900 CPU cooler when trying to place the metal clip over the lower portion of the hold down plate.

Now it is time for us to turn our attention over to the DIMM sockets. AMD only supports Dual Channel memory, so it is only natural for us to see four DIMM sockets. Right below the DIMM sockets we see an IDE expansion port, a Floppy connector, and the 24 main power plug. Right above the main power plug, Gigabyte includes onboard on/off reset switches. These are also located in a very easy to get to location.

Looking at the 180° SATA 3 connectors.

Now the one area that Gigabyte normally has issues with is the upper most PCI-E port, which sometimes interferes with the NorthBridge. This time around Gigabyte did a good job on making sure the top PCI-E port is clear from the NorthBridge heatsink. We will have to see how things fair once I use the NorthBridge cool and quite heatsink.

Looking at the rear I/O ports, starting at our left then working right; we have a single PS/2 port with two USB connectors. Moving to the right, you get two Audio Optical ports, then moving farther to the right, Gigabyte includes a standard Firewire 1394 port with a USB power 3 port, and finally an external E-SATA connector. Then you get another Firewire port, followed by another USB power 3 port, finally another E-SATA port. You get an Ethernet/USB header, followed by another Ethernet/USB 3 port this time. (Blue USB ports are USB 3, Yellow USB ports are Gigabytes USB power 3; then finally you get onboard 7 channel audio.



Here are some extra pictures for you to gaze over to get an idea on how Gigabyte assembled this motherboard.


This is Gigabyte’s very own Cool and Quiet NorthBridge heatsink. This can be used in place of the water block that Gigabyte uses. Installation is fairly straight forward; you shouldn’t have any issues putting this on.
Tip: I found it best to install this heatsink onto the motherboard prior to installing it into a chassis. You will be using one less screw that will hold the motherboard on (that screw goes right below this heatsink) but I found it easier to leave this screw out for a quicker and easier motherboard installation and removal.

Talk about wall to wall coverage on a motherboard, this motherboard is so huge!

Here is what the Gigabyte 890FXA-UD7 motherboard looks like when installed into the SilverStone RV-02 chassis. Even though this chassis has the right number of expansion openings, the 890FXA-UD7 barely fit. Make sure your chassis is big enough to handle this motherboard. Make sure your chassis supports at least 8 expansions, 9 would be preferred.

To fully gauge the performance level of both of the Gigabyte 890FXA-UD7 and the AMD 1055T six core CPU, I will be putting this up against my Intel Core i7 930 CPU on my Asus P6X58D-E motherboard. Also, I will compare the Gigabyte/AMD combination up against the Intel Core i5 750 CPU paired up with the Asus Sabertooth 55i motherboard. Since I just did an AMD x3 445 CPU review paired up with a Gigabyte 890GMA-UD2H motherboard, I will also be including this combination in the charts. This should give you readers a well rounded comparison of motherboard/CPU combinations. I will only be overclocking the Gigabyte 890FXA-UD7/AMD 1055T hex core CPU. Overclocking varies from machine to machine, this is to give you an idea on what the motherboard and CPU can do.

I will be using the absolute baseline speeds on all motherboards tested. For testing purposes, I ran each program a minimum of three times to ensure accuracy of each programs scores and performance numbers. All testing was done on a fresh Windows 7 64 bit install.

When I first received the CPU and motherboard I could not wait to see what this combination could do. But the issue I had was I did not know how to go about doing what I had set out to do. I sat here scratching my head for the first few minutes while I waited for Windows 7 to finish installing, thinking on how to overclock this combination. It had been a while since I had an AMD setup in the house for me to torment the hell out of it.

I decided to fall back on the all time favorite of mine, and see how things fair from there. That all time favorite is for me to start pushing buttons till either I catch the house on fire or the CPU/motherboard submits to my will, bwhahahaha! During my time with this CPU, I kept the CPU under water. I wanted to make sure things stayed as cool as possible.

After fiddling around with different settings, I finally was able to hit my max CPU overclock without needing those crazy voltages. That maximum overclock I achieved was 4GHz on the AMD 1055T CPU. Not too bad if I may say so myself.


Default settings

Overclocked settings.

BIOS Part 1

 This is how Gigabyte laid out the BIOS of the 890FXA-UD7 motherboard. As we can already tell, Gigabyte has been using this layout for years on their motherboards. There is enough information given for any of us to make any adjustment we need with this motherboard. We can also save up to 8 personal overclocking profiles by pressing the F11 key on our keyboard. To load that Profile all we need to do is press the F12 key and select that profile we want loaded.

BIOS Part 2

This portion of the BIOS is the M.I.T., where we can really fine tune our motherboard to what we want. Or in my case “Bend the Gigabyte 890FXA-UD7/AMD 1055T CPU to my will, bwhahaha!”. The only thing that I thought was rather different, from what I am used to, is that we don’t actually see the physical voltage adjustments, instead we overvolt them by predetermined settings.

Let the Battle Begin

The Default AMD 1055T paired with the Gigabyte 890FXA-UD7 motherboard is green and the Overclocked AMD 1055T paired with the Gigabyte 890FXA-UD7 is yellow.


  “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.”

Starting off with one of our all time favorite benchmarks, the AMD 1055T CPU and the Gigabyte 890FXA motherboard combination performance sits in between the Intel Core i5 750 CPU and the Intel Core i7 930 CPU. This is not a bad place to be at considering the AMD 1055T CPU goes for the same price as the Core i5 750 CPU.

During our multimedia benchmarking, we see the all out raw power and the AMD 1055T start to show its might. Surpassing not only the Core i5 750, the AMD 1055T and the Gigabyte 890FXA combination, but also surpassing the Core i7 930 setup.

 Intel still shows its supremacy when it comes to memory bandwidth, when compared to the AMD CPU offering.

It appears that SiSoft is giving us the same latency on the memory on both the Core i7 930 platform and the AMD 1055T/Gigabyte 890FXA combo.

Reminder: The Default AMD 1055T with the Gigabyte 890FXA-UD7 motherboard is green and  the Overclocked AMD 1055T with the Gigabyte 890FXA-UD7 is yellow.

Now with Everest testing of the memory bandwidth, once again the AMD combo is still the lowest performing. Not even overclocking of the AMD 1055T/Gigabyte 890FXA combination could keep up with either one of the Intel CPU motherboard combinations.

Just like the SiSoft latency testing, it appears that the AMD 1055T/Gigabyte 890FXA combination can put out some rather nice results.

During Our CPU portion of testing, we get a mixed set of results. During the Julia portion of testing, the AMD 1055T CPU is just trailing the Core i7 930 CPU. On the CPU Queen testing portion, the AMD 1055T CPU surpasses the mighty Core i7 930 CPU.

Reminder: The Default AMD 1055T with the Gigabyte 890FXA-UD7 motherboard is Green and the Overclocked AMD 1055T with the Gigabyte 890FXA-UD7 is yellow.


wPrime is a benchmarking application designed to use a highly multithreaded approach to calculating the square-roots of large amounts of numbers (up to 32 billion).

 wPrime is showing us that the AMD 1055T CPU combination performance sits in between the Intel Core 5 750 CPU and the Core i7 930 CPU. Once again, not bad performance levels from the AMD 1055T CPU.


 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.

During the POV Ray rendering test, the AMD 1055T CPU is even with the mighty, all time favorite, Intel Core i7 930 CPU on performance levels.


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.

It appears that Microsoft’s Excel still prefers to have an Intel based CPU at its disposal.

The War Rages on

Reminder: The Default AMD 1055T with the Gigabyte 890FXA-UD7 motherboard is green and the Overclocked AMD 1055T with the Gigabyte 890FXA-UD7 is yellow.


 AutoMKV is an application aiming for easy media conversion between various media formats using various third party codecs. With improved internet speed and enhanced computing power, more users are interested in encoding to different media formats for their various multimedia needs. With AutoMKV and x264 codec, a freeware H.264 encoder, users can easily create media files. For more information and to obtain AutoMKV 0.95c and AviSynth* 2.5.7, please visit ( We create a media file using AutoMKV and x264 codec. The input file used in the document is a raw 416 MB 720×480 DV file and the output is a 253MB H.264 media file.

Let’s see how things fair once we kick up AutoMKV. Hmm, AutoMKV also prefers the Intel based CPU’s vs having an AMD CPU. This is where having memory bandwidth really starts to count.


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.

The AMD 1055T CPU manages to squeeze itself in-between the Intel Core i5 750 CPU and the Intel Core i7 930 CPU during our compression testing of 4 large TIF files.

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.


Now it is time for us to see how the AMD X3 445 CPU/Gigabyte 890GMA-UD2H combination fares with 3DMark Vantage while having a Sapphire 5870 Vapor X strapped to it. 3DMark Vantage is one of those benchmarks that loves to have both multiple CPU cores and also have high CPU core speeds. The performance levels we see here are not all that great, but then again, they aren’t all that bad. This is about where we would expect a X3 CPU to perform.

During the CPU physx testing portion of 3DMarks Vantage testing, we are seeing the performance level of the AMD 1055T CPU. Once again the AMD 1055T sits in between the Core i5 750 CPU and the Core i7 930 CPU.

Dirt 2

Now these results seem to sting the AMD 1055T CPU a bit. The AMD 1055T performed the worst with Dirt 2. But keep this in mind, having a minimum of 34.7 FPS is still very much playable.

Unigine Heaven

Unlike Dirt 2 testing, it does not matter what CPU you are using. We get the same exact frame rates. So it really depends on the game type where we will start seeing differences from one game to the next.


As you can see, the Gigabyte 890FX-UD7 with the AMD 1055T CPU is a rather powerful solution for just about anyone. This combination was handling anything I could throw at it, and then keep asking me for more through out my testing. Even I have to admit that if I did not already have my current Intel Core i7 930 system, I would seriously consider this CPU as a possible candidate for my computer.

As good of a combination the AMD Hex core 1055T CPU and the Gigabyte 890FXA-UD7 motherboard is, I had a small issue when it pertained while trying to Crossfire my two 5750 video cards. No matter what I tried (switching the video cards to different PCI-E ports) I could not get my two 5750’s to Crossfire. After a few emails back, and forth between myself and one of Gigabyte’s technicians Leo; one of the two 5750’s is a Asus 5750 Formula while the other 5750 referenced design VisionTek. I did not have any issues trying to Crossfire these two video cards on my other two Intel based machines. Leo over at Gigabyte, was able to Crossfire two 5750 video cards with the 890FXA-UD7 motherboard he was using. I am guessing he was using two matched sets of 5750 video cards; where my two were different manufactured video cards (Asus and a VisionTek). Leo sent me the 890FXA-UD7 he was using for his testing, when I received that motherboard I tried Crossfiring my two 5750 video cards on that motherboard.

Unfortunately I was unable to crossfire my Asus and VisionTek 5750s on that motherboard as well; which gave me the idea that not everything is 100% compatible. Things like this does happen, as much as we don’t like this incompatibility issue, it does happen from time to time. So I will not hold this minor problem against the Gigabyte 890FXA-UD7 motherboard.

Looking around the internet for pricing on the 890FXA-UD7, and I found that this motherboard can be purchased at for around 250 USD. For a motherboard that can be expanded like this one can (Support four way Crossfire), it makes this a good deal for anyone wanting to have an ultimate gaming rig.
