Gigabyte X79-UD3 review

High-performance Sandy Bridge E hero

TODO alt text

The verdict on the Gigabyte X79-UD3 will come down to what it does and doesn't do.

What it undoubtedly does is deliver performance pretty much indistinguishable from any other X79 board in the known universe. That includes stock clocked performance, where there was never likely to be much of a chasm, and also overclocking headroom.

The UD3 has plenty of the latter.

Indeed, records have verily been broken with the Gigabyte X79-UD3. An expert overclocker, known nattily as 'Hicookie', is alleged to have nailed 5.6GHz with a Core i7 3930K.

You also get a simple but sleekly presented board that oozes quality and a pukka UEFI BIOS menu that includes all the configuration options you could ever desire.

Oh, and Gigabyte has also thrown in four PCI Express x16 slots (two are 8x electrical) for four-way SLI action, should you be so inclined.

The final highlight is a pair of USB 3.0 chips and thus up to four USB 3.0 ports (two via a header).

At this point, the argument in favour of spending more than the Gigabyte X79-UD3's £175 asking looks pretty precarious. However, what it doesn't do it give you is the frills of a fancier board.

There are no on-board buttons for power, reset or overclocking, for instance. There's no auto-overclocking facility in the BIOS, either.

Likewise, one DIMM slot per memory channel is your lot, for a grand total of four. On that subject, the memory slots and primary PCI Express slot are situated too close together, putting graphics cards at risk during insertion.

We liked

The Gigabyte X79-UD3 ain't exactly cheap, but it is one of the most affordable X79-based boards you can buy.

It also delivers excellent performance, both stock and overclocked, support for up to four graphics cards, four USB 3.0 ports and six SATA 6Gbps sockets.

We disliked

As this price point, something's gotta give.

Gigabyte has stripped the X79-UD3 of extras such as power and reset buttons along with the extra memory slot per channel seen on pricier boards.

Our testing also suggests the UD3 is a little power hungry on full reheat.
