In contrast to previous generations where Gigabyte have released a dozen or more models in a range, the X79-UD5 is one of just four clearly delineated models along with the UD3, UD7 and G1 Assassin 2. Gigabyte is pitching the feature packed UD5 at content creators, professionals and any users requiring memory capacity with heavy multithreaded CPU workloads. The other boards cover the budget (UD3), gaming (G1 Assassin) and overclocking (UD7) segments. Notably, the UD5 is the only board in the range to feature eight DIMM slots and therefore the only one that supports the full 64gb memory capacity of the platform. This fact alone will appeal to many users.

Before we dive into the UD5 itself, below is a general overview of the X79 platform supporting 2nd generation Intel i7 processors for the LGA2011 socket. The increased number of PCIe lanes and quad channel memory support are the major distinguishing features over the mainstream P67/Z68 platforms.

Additional note:

Since the release of the UD5, Gigabyte issued a statement urging users who overclock their boards to update to the F7 or later BIOS. The new BIOS' update some protection mechanisms relating to the PWM. The update is only necessary for users with heavily overclocked systems. Day to day users won't notice any difference even if they don't switch to the new BIOS. They went as far as offering an unconditional five year warranty on the boards to alleviate concerns. Gigabyte in house overclocker Hicookie went on to claim several overclocking records with the new BIOS, debunking some unjustified forum scare-mongering. Our own overclocking tests resulted in no issue whatsoever with both the old BIOS and the new.
