GIGABYTE X79-UD7 Overclocking Review

Let’s take a look at GIGABYTE's latest top dog overclocking LGA2011 motherboard, the X79-UD7. It is equipped with slot configuration for quad SLI, a new IR digital PWM with a 16 phase VRM, tons of cool overclocking features all in an XL-ATX form factor. Follow us as we go over every single feature, test out GIGABYTE's new UEFI BIOS, and overclock this bad boy. We will do a comparison of stock VS a typical high end overclock for 24/7and see how much performance we gain. So let’s take a look at what GIGABYTE has dished out as their new OC board!


Today we venture into the world of GIGABYTE's LGA2011 top overclocking board, the X79-UD7. With all the dazzle of their X58A-OC GIGABYTE has produced a quite similar beast in terms of features and specs. The X58A-OC was a board targeted towards overclockers and only overclockers, since then we heard that GIGABYTE sales decided that a board with the -OC moniker wouldn't sell well. So now it looks like GIGABYTE has replaced their traditional UD7 with a sort of hybrid. The X79-UD7 doesn't carry many more features than the other boards when it comes to connectivity, but it is unique in its own right. Equipped with only 4-DIMMs compared to the UD5's 8, and with the ability to run quad GPU configurations in an XL-ATX (1 expansion slot more than regular ATX) package, the UD7 is an overclocker's dream or so it seems. If you owned or saw the original X58A-OC you've witnessed GIGABYTE's finest OC board with the exception of the X58A-UD9. When you look at the X79-UD7 you see an uncanny resemblance to the X58A-OC. It might be because of the orange/black color scheme, or the frequency buttons and read points, or maybe the hefty VRM and dual 8-pin power connectors that give it away but the X79-UD7 is an X79-OC in disguise. 

The X79 chipset has all the goodies one could ever imagine, except for a few things. First off it is missing USB 3.0, something we hope to see with Intel's Z77 chipset. Second it is missing all of those SAS/SATA6GB/s ports we saw at IDF! That was a lot of SATA/SAS and now we have none of it, we basically have a redo of the Z68 chipset just without SSD Caching and iGPU support. What is more interesting about the LGA2011 platform is what is the CPU has in store for us. Even though the current LGA2011 CPU's lack virtualization and PCI-E 3.0 certification, they still have many features. Quad channel memory controller with supreme overclocking abilities is a plus as is PCI-E 3.0 which can't be claimed until the second stepping gets PCI-SIG certification. We seem to take for granted the 40 PCI-E lanes and native Quad SLI/CF support. With LGA2011 we have Intel moving back to satisfy the overclocker, of course not how we would like, but BLCK straps are nothing to push to the side. Today we will take a look at GIGABYTE’s top LGA2011 board for overclockers, let’s see how it does.
