Introduction to the Gigabyte GA-X79-UD3 Socket 2011 Motherboard

The launch of the latest AMD chipset, the 990FX just a few months ago bought us once again into an area where there would a ton of motherboards to test and write about. Its time like this that most reviewers, testers, benchers and bloggers really enjoy doing what they do. Yes, the time spent to get the article done in a meaningful time is a little tedious but it is still fun.

Now, it is Intel’s turn to unleash some new tech on the market. With the not so-hot performance of the AMD Bulldozer, it is up to Intel to provide us with the performance numbers we want in an upgrade from our old tired out systems. The X79 chipset was just released a couple of months ago with some pretty decent performance numbers but at a cost that many would have to wait for next mainstream chipset.

Many motherboard manufacturers like Gigabyte are well aware that many of us are not willing to pay an arm and a leg to get the next generation set of goodies. Yet, they can do nothing about the price of the CPU itself but they can sure do something about the pricing of the motherboards. Gigabyte on launch rolled out a series of motherboards that covers every sector of computer users based on the X79 chipset.

Closer Look

To begin the X79-UD3 is one of just four motherboards by Gigabyte to support the Intel socket 2011 processor. And at any rate I am sure you will see quite a few more to be released. The series consist of G1.Assassin2, UD7, UD and other test board today, the UD3. Granted the UD3 is the lowest of the four models but it does pack several features that will be looked for in a motherboard of this type. Support for overclocking, big time gaming and the all important stability. And because Gigabyte is so proud of their new offering they are backing the series with a five year warranty.

Strange to many of us is the location of the DIMM slots. No longer are all the slots located on the right corner of the motherboard which traditional has come to show us. Even number of slots are now located on each side of the CPU socket. In this case there are two on each side. Many of the mid to high-end motherboards will be equipped with three or four on each side. Due to a possible 25GB/s bus potential the X79 chipset now supports quad-channel memory addressing.

This particular motherboard supports a total of 32GB of DDR3 memory including 1066/1333/1600/1866 and 2133MHz modules. But one has to remember that the new processors have an integrated memory controller that is native to 1600MHz. So, anything above comes from the overclocking process.

The X79 chipset is only intended for socket 2011 processors like the 3960X and the 3930K. And with this being said new cooling hardware will need to be used. We have received several press releases of companies like Thermaltake and Noctua offering new mounting systems for some of their already made coolers.

With the CPU socket surrounded by DIMM slots and other components that may cause concern for those that want to use bigger coolers. We will take a more in depth look at this later. The UD3 uses an 8 phase power system to deliver reliable power to the CPU. And being part of the Ultra Durable 3 line-up the board uses all Japanese capacitors, lower RDS MOSFETS and ferrite core chokes. All benefiting you in various areas like lower overall operating temp of the motherboard, less wasted power and stability.

For a lesser end motherboard the UD3 has quite a few PCIe slots. There are two x16 and two x8 bandwidth slots which are all PCIe 3.0. Below the first and second longer slots are two x1 slot. And for legacy purposes there is a single PCI slot. For those wanting multi-GPU configurations the UD3 does support SLI and Crossfire up to 4-way.

In need of storage support look on further. The UD3 has a total of ten SATA ports. Starting from the right the two white ports is SATA III (Intel X79), four black ports are SATA II (Intel X79) and four gray ports are SATA III and controlled via a Marvel 88SE9172 controller. The Intel based ports support RAID 0, 1, 5 and 10 while the Marvel units support RAID 0 and 1.

The UD3 also gives you all the small comforts of the more expensive motherboards. There is a total of five fan header to control more than the minimum amounts to keep a system cool and air properly circulating. The AUX CPU power connector is located where behind the VRM and phase heat sink.

And speaking of heat sinks the UD3 has a total of two; the above mentioned one as well as one for the PCH. We have seen before launch that a number of motherboards are using active cooling on the PCH. But not in this case we assume the reason is overall overclocking that can be done on this board.

  • PS/2 (mouse/KB)
  • 10x USB ports (8x USB 2.0 & 2x USB3.0)
  • 2x eSATA (Marvell 88SE9172)
  • 1x LAN port (Intel)
  • 7.1 channel audio (Realtek ALC898)

wPrime is a leading multithreaded benchmark for x86 processors that tests your processor performance by calculating square roots with a recursive call of Newton’s method for estimating functions, with f(x)=x2-k, where k is the number we’re sqrting, until Sgn(f(x)/f'(x)) does not equal that of the previous iteration, starting with an estimation of k/2. It then uses an iterative calling of the estimation method a set amount of times to increase the accuracy of the results. It then confirms that n(k)2=k to ensure the calculation was correct. It repeats this for all numbers from 1 to the requested maximum.

SiSoftware works with all major hardware vendors to ensure we can accurately measure, report and present performance in the most accurate and informative way.
A year ago, SiSoftware released Sandra 2010 with full support for Windows 7; in the 18 months since the launch of Windows 7, more than ever before we have seen the line blur between PC and entertainment hubs. Two months ago we released a Blu-Ray benchmark, now we have added a brand-new Media Transcoding benchmark using the new Media Foundation of Windows 7. We have also added yet another benchmark (GP Cryptography) which allows direct comparison of CPU performance (using crypto instruction sets) and GPGPU/GPCPU/GPAPU performance.

Super PI Modded 1.5
In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo. The program was written by D.Takahashi in collaboration with Dr. Y.Kanada at the computer center. This record should be the current world record. (Details are shown in the windows help.) This record-breaking program was ported to personal computer environment such as Windows NT and Windows 95. In order to calculate 33.55 million digits, it takes within 3 days with a Pentium 90 MHz, 40 MB main memory and 340 MB available storage.

Geekbench 2.2.7
Geekbench provides a comprehensive set of benchmarks engineered to quickly and accurately measure processor and memory performance. Designed to make benchmarks easy to run and easy to understand, Geekbench takes the guesswork out of producing robust and reliable benchmark results.

PiFast is an easy-to-use package written by Xavier Gourdon to compute p with a very large number of digits. PiFast is avalaible on several platforms, download it from here. PiFast can also compute E and a large family of user defined constants.


The Gigabyte X79-UD3 on the surface looks to be a very solid choice for anyone looking to pair it with the Intel i7-3930 socket 2011 processor. At the time of this writing this motherboard and processor was one of the cheapest around without taking into account rebates and special orders. But besides price, Gigabyte did do a good job of building a very motherboard with a lot of high qualities.

Just a couple of exterior ways we saw Gigabyte cut cost was to first eliminate four of the eight DIMM slots. This here will limit the user when it comes to the max amount of memory supported. But honestly most enthusiasts as well as gamers are truly satisfied with 2x4GB kits. But the price of 16GB kits is dropping to a more subtle price point so there is an option as well. Cooling was another area we saw very little of. Some of the higher end motherboards have large heat sinks along with active cooing to take care of the heat produced by the PCH especially doing overclocking sessions.  The UD3 does lack the number of SATA ports compared to several of the motherboards out there. But the chance of many of us needing to occupy more than ten storage devices is slim.

Enough about what the UD3 doesn’t have and more about what it does have. First, would be the fact it does support multi-GPU setups up to 4-way configurations. This is definitely a way to increase your gaming performance as time goes by. The 8 phase power configuration is first allow for very good stable and reliable power to the CPU, memory slots as well as other areas of the motherboard. Second, it allows for some decent 24/7 overclocks.

And for those that are external storage freaks or have a lot of peripherals that need to be connected to USB ports, you will be glad to know this motherboard has several. A total of ten are present and throwing in the USB headers on the motherboard a whole lot more can be added. And if you plan to add (or have) some form of front panel USB 3.0 device there is even a header on the motherboard to support that.

Even with the overclocking slightly different from the Sandy Bridge processor, the X79-UD3 did a good job on our retail 3930K Sandy Bridge E processor. Our limit with the modest voltage increase to 1.4v resulted in a 4.6GHz very stable overclock.

We feel that the Gigabyte X79-UD3 is worth every penny it cost which is about $230. This is the lowest price range of the X79 lineup from any manufacturer. Matched with the new Intel Core i7 3820 is a match well worth looking into.
