Gigabyte H55M-USB3

Gigabyte H55M-USB3 is a nice M-ATX board that features USB 3.0 and RAID functionality all for $100. For the socket 1156 processor, this could be one of the best buy for its feature and performance.


When Intel’s Clarkdale-based processors were released this past January, Gigabyte jumped into action creating some of the best H55 boards available. With the new Clarkdale-based processors, the H55M includes built in graphics, making this setup great for people looking to build smaller PC’s like HTPC’s, small form factor web PC’s, and small servers. With low power consumption and no need for a GPU (due to Intel’s Clarkdale-based CPU), these computers save power and and are extremely efficient. The H55M USB3 we are looking at today also enters the new world of USB 3.0, giving this new setup an extra advantage.

As we test Gigabyte H55M-USB3, we will contrast it with the the Asus P7P55D Premium board, so that we can see a performance comparison between the H55 and P55 chipsets. Both the P55 and the H55 support socket 1156 processors. The more expensive P55 comes with the ability to run SLI and RAID support, users who do not want these features can save money by choosing the H55. Let’s examine these two boards in greater detail.

Pictures & Impressions

The front of the box provides some general information on the Gigabyte H55M USB3, and gives some information about new features like USB 3.0.

The rear side of the box gives more detailed information on features unique to Gigabyte’s motherboards. Features such as Ultra Durable 3 and Dynamic Energy Saver 2 are meant to prolong the lifespan of the motherboard and reduce overall system power consumption. SMART6 is a 6 tool software suite that helps “speed up system performance, reduce boot-up time, manage a secure platform and recover previous system settings easily with a click of the mouse button.”

The motherboard comes with an I/O shield, 2 SATA cables, 1 IDE cable, 1 FDD cable, a manual, and a SMART6 guide.

One of the first things we noticed about this motherboard is that the CPU socket has moved a bit closer to the center of the board rather than closer to the back I/O ports. This allows users to install larger CPU coolers.


The rear I/O includes the usual ports: a PS/2 for a keyboard or a mouse, four USB 2.0, two USB 3.0 (colored blue), one eSATA port, one optical SPDIF, a Gigabit Ethernet port, and the usual 8 channel audio ports. The board also comes with a variety of video ports: D-Sub, DVI, HDMI, and DisplayPort. Though it is a bit crammed, these ports eliminate the need for large adapters. The addition of the newly introduced DisplayPort ensures that the board will work with future displays.

The onboard audio chip Realtek ALC889 is sufficient for most users. While it cannot compete against a dedicated sound card, it is good enough for basic sound playback. It has ten DAC channels that simultaneously support 7.1 sound playback, and 2 channels of independent stereo output (multiple streaming) through the front panel stereo port. 


The board comes with seven SATA ports. The blue ports are controlled by the Intel chipset, and the white ports are controlled by the board’s own SATA2 chip. Gigabyte routed one of the Intel-based SATA ports to the back for the eSATA. One thing to note is that the RAID functions are controlled by Gigabyte’s onboard SATA2, and not the Intel H55 chip. The board supports RAID 0, 1, and JBOD configurations. 

Although the SATA ports are not angled, they are sufficiently far away from the PCI-E slot that there should be no space issues.


Along the bottom edge of the board is the usual USB 2.0 header, the front power, reset, HDD LED, power LED, and speaker ports. In addition to the three USB 2.0 header, there is also a FireWire header, COM port, and SPDIF header.


An angle shot showing the 1156 socket and MOSFETS and ferrite core chokes. Also pictured is the CMOS battery. Due to its proximity to the CPU socket, the battery may be difficult to remove, especially if large coolers are used.

There is no heatsink above the PWM so the CPU socket area is completely clear from any obstruction. However, the DIMM slots are somewhat close to the CPU, so users may have to remove their CPU heatsink to change their memory.


Close up view of the new LOTES 1156 CPU socket.

The board has four DIMM slots, for up to 16GB of DDR3 2200+/1800/1600/1333/1066/800 MHz memory modules. Intel Extreme Memory Profile (XMP) is supported. The DIMM slots sit very close to one another, and users whose memory modules have bulky heatspreaders may not be able to use all four slots.

Next to the memory slots are floppy, IDE, and 24-pin ATX power connectors. The close proximity of these connectors to the memory could be a problem for those who use all four power connections.The bulkiness of these cables can also make cable management difficult.

For expansion, the board comes with one PCI Express x16 slot, one PCI Express x16 slot running at x1, and two PCI slots. With two PCI-E slots, users can install any card, albeit at reduced speed, as long as it is backwards compatible to x1 (most video cards nowadays are only backwards compatible to x8). As it stands right now, the board cannot support SLI or CrossFire technology. It could if Gigabyte were to implement a switch to split the x16 into x8/x8 configuration, but given the target market, we do not believe most boards will have such an option. Users who want SLI or CrossFire should choose boards based on the P55 chipset.

The spacing and the location of the individual expansion slots is good. The placement of two PCI slots between the two PCI-E slots is beneficial, so even if users install a large graphic card like a GTX 480 or HD 5870, it will only block the PCI slot next to the first PCI-E, so leaving a PCI and a PCI-E x1 available for add-on cards.

One major shortfall in this board’s design is the lack of space between the PCI-E slot and the DIMM slots. This makes it impossible to add or remove memory without removing the graphics card.


A close up view of the PCH chip heatsink.

The heatsink comes a bit close to the release latch of the second PCI-E slot, which would make it very difficult to press the latch when removing a card from the second slot. However, since the slot is running at x1, it is improbable that users would put a video card in it.

Next to the SATA ports is the Clear CMOS jumper.


Gigabyte uses an Award BIOS for the H55M-USB3. As usual, Gigabyte places most of the overclocking settings in their “MB Intelligent Tweaker (M.I.T.)” menu.

The BIOS has a general overview, including basic settings for the CPU and memory when you get into the M.I.T. menu. We like the way the menu is organized. It’s good that Gigabyte also shows the CPU and PCH temperature here so overclockers can keep an eyes on this information while they push their system.

In the Advanced Frequency Settings, users can adjust their CPU clock speed. The H55M-USB3 allows BCLK frequencies of 200 MHz to 1200 MHz in increments of 1MHz, plenty for most hardcore overclockers. The PCI Express frequency can be adjusted from 90 MHz to 150 MHz in increments of 1 MHz.

In addition to the frequency adjustments, overclockers can adjust the CPU clock drive and the PCI-E clock drive to increase voltages for system stability. Both of these settings can be adjusted from a selection of 700mV, 800mV, 900mV, and 1000mV.

The Advanced Memory Settings menu lets users fine-tune their memory timing, speed, and memory related voltage. The board supports Intel XMP profiles but users can override the profile and manually adjust them. Below is a summary of different settings: 

Settings Options
Channel Interleaving 1-6
Rank Interleaving 1-4
CAS Latency 6-15
tRCD 1-15
tRP 1-15
tRAS 1-31
tRC 1-63
tRRD 1-7
tWTR 1-31
tWR 1-15
tWTP 1-31
tWL 1-10
tRFC 1-255
tRTP 1-15
tFAW 1-63
CMD 1-3

Gigabyte lets users adjust the CPU Vcore, QPI voltage, GPU core voltage, PCH core voltage, CPU PLL, and DIMM voltages.

As we can see, though it is a budget board, the Gigabyte H55M-USB3 has plenty of overclocking potential.

Testing & Methodology

For this review, we did a fresh load of Windows 7 64-bit and updated the Operating System and drivers to all the latest versions and patches. Then we loaded the testing software and ran the machine for a few days to confirm everything was installed correctly, and gave the machine a little burn-in time.

For this review, we have used the same hardware that we’ve been using on all our motherboard reviews in this series. We used the same HDD, CPU Cooler, RAM, and CPU. This consistency will allow us to make more accurate comparisons, as the other hardware will not affect results across our wide spectrum of tests.

As we stated in the introduction, we are not going to go through a long list of benchmarks for this review. Instead, we will test this board against the more expensive P55 board, to find performance differences between the two. We are hoping that this will help buyers to decide between the two chipsets when it comes to shopping for a board for a Socket LGA1156 processor.

Test Suite

Synthetic Benchmarks

3DMark Vantage

AutoMKV 0.95C

SiSoft SANDRA XII Professional SP2

Everest Ultimate Edition v. 5.30



Microsoft Excel 2007

WinRar v. 3.71

The benchmarks include some synthetic and some real-world tests. Hopefully this will shed some light on the performance differences between the two chipsets.

Everest Ultimate v. 5.30

“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.”


This integer benchmarking application measures CPU performance using AES (a.k.a. Rijndael) data encryption. It utilizes Vincent Rijmen’s, Antoon Bosselaers’, and Paulo Barreto’s public domain C code in ECB mode.

CPU AES test uses only basic x86 instructions, consumes 48 MB memory, and is Hyper Threading, multi-processor (SMP), and multi-core (CMP) aware.


The Asus P55 board is based on a more mainstream chipset, but the H55 based chip performs quite well. The P55 board has a slight lead but it is less than 1% over the H55M. 

CPU PhotoWorxx

This benchmark performs the following tasks on a very large RGB image:

• Fill

• Flip

• Rotate90R (Rotate 90 degrees CW)

• Rotate90L (Rotate 90 degrees CCW)

• Random (Fill the image with random colored pixels)

• RGB2BW (Color to black & white conversion)

• Difference

• Crop

This benchmark stresses the integer arithmetic and multiplication execution units of the CPU and memory subsystem.

As with CPU AES, CPU PhotoWorxx uses only basic x86 instructions, and is Hyper Threading, multi-processor (SMP), and multi-core (CMP) aware.


The P55 has a lead of 1.7% over the H55M. In practical use, users should not feel a difference.

CPU Queen

This simple integer benchmark focuses on the branch prediction capabilities and the misprediction penalties of the CPU. It finds the solutions for the classic “Queens problem” on a 10 by 10 sized chessboard.

CPU Queen test uses integer MMX, SSE2 and SSSE3 optimizations. It consumes less than 1 MB system memory and is Hyper Threading, multi-processor (SMP) and multi-core (CMP) aware.

Unsurprisingly, the P55 chipset stays above the H55M, but only slightly.

Everest Ultimate v. 5.30 Memory Suite

This test shows a huge performance disparity between the two boards. Despite using the same memory chip and integrated memory controller, the Asus board comes out on top.

The H55M-USB3’s memory latency is also a bit slower than the Asus board.

Sisoft Sandra

“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.”

Unsurprisingly, the P55 performs better than the H55M.

The greater memory bandwidth of the Asus board is probably why the P55 performs better than the Gigabyte board in both processor tests. Everest shows that the disparity in raw CPU power is not enough to account for the disparity in performance. We can conclude that the memory bandwith is most likely the reason.


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)

A synthetic benchmark is not always an accurate indicator of real-world performance. Here, we will examine how the boards perform in real-life tests.

In the wPrime results, we can see that the Asus board is about 5% faster than the Gigabyte board.

AutoMKV 0.95c

AutoMKV is designed for easy media conversion between media formats using various third party codecs. Due to improved internet speed and enhanced computing power, more users are interested in encoding 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 on AutoMKV 0.95c and AviSynth* 2.5.7, please visit ( In this test, 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.


In addition to the raw processing power, the memory bandwidth plays an important role in video transcoding. Here we can see that the Asus board has a clear advantage, finishing the job 38.4 seconds faster than the Gigabyte board.


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

The workload consists of an approximately 6.9 MB character model of a flying squirrel. Due to time constraints we don’t render the entire image, as the only result would be larger benchmark numbers (the ratios between the two results would stay the same). A portion of the image suffices for our purposes, as it is large enough to show differences in CPU performance, yet small enough that it can be performed in a reasonable amount of time.

This test also puts great stress on the combination of the memory and the CPU. The Asus board clocks in at 18.8 seconds ahead of the Gigabyte board.

Microsoft Excel 2007

Monte Carlo Black-Scholes Option Pricing Test

Microsoft Excel is the most widely known and used spreadsheet application for number manipulation and calculation. Excel allows users to analyze and share information on any scale imaginable. We have 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 the 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 the 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.

Big Number Crunch

This workload is from a 6.2 MB spreadsheet and executes about 28,000 sets of calculations. It uses the most common calculations in Excel: addition, subtraction, division, rounding and square root. It also analyzes statistical functions such as Min, Max, Median, and Average. The calculations are done after a spreadsheet with a large data set is updated with new values, so the computer must recalculate a large number of data points.

The P55 comes in ahead in both of our Excel number-crunching tests. It is worth noting however, that for all its increased performance, the P55 board costs about twice as much as the H55M.

3DMark Vantage is the newest video benchmark from Futuremark. Though still a synthetic benchmark, it closely reflects real-world gaming performance. While it is not a replacement for actual game benchmarks, it has its uses. We tested our cards at the ‘Performance’ setting.


3DMark indicates that the Gigabyte board is actually not a bad choice for a budget gaming system when paired with a dedicated graphics card. We can see that the board scored quite well compared to the Asus board. In terms of gaming, the GPU is often the limiting factor, so the lower memory bandwidth we observed with the H55M chipset should only be a minor factor.

For a budget gamer, the single PCI-E x16 should be plenty, because the need for dual video cards is unlikely. Pairing this board with a Core i3 530 or 540 and an ATI HD 5770 would make a very capable gaming system for under $500. This would let users play most current games up to resolution 1920×1200 with some eye-candies enabled.


The Intel H55 chipset is certainly a capable budget chipset for Socket 1156. As our tests have shown, the biggest performance difference between the two chipsets is the memory bandwidth, in which P55 has a clear advantage. Despite this difference, the two chipsets perform virtually identically to each other, with the P55 performing 1 to 5% better in different benchmarks. In applications, such as video encoding and Excel Number Crunching, the P55’s extra memory bandwidth shows a clear advantage. However, in games, it is not as apparent, as game performance is often GPU-bound than CPU/memory bound.

Besides the performance difference, there are some other things to consider when choosing between the two chipsets. The H55 comes with only 1 PCIE x16, and 12 USB 2.0. The P55 actually also only has PCI-E x16 but can be configured in SLI/CrossFire configuration, and has 14 USB 2.0 ports (two more than the H55). Ultimately, the H55 is not a bad choice, and the features that are missing most likely will not be used much in a budget system.

The Gigabyte H55M-USB3 is one of the best H55 boards money can buy. At retail price of $100, the board adds the RAID 0 and 1 capability, making it even more appealing. In addition, we are glad to see the inclusion of USB 3.0, DisplayPort, and HDMI on the board. Despite a layout issues, the board has plenty of excellent features that make it one of the best boards for budget buyers.
