At a price point of $189.00, the Gigabyte GA-990FXA-UD5 falls into the Enthusiast class of motherboards.


Performance of the Gigabyte GA-990FXA-UD5 was excellent across the board. All drivers worked flawlessly on first install with no tweaking necessary. The BIOS of the GA-990FXA-UD5 offers excellent options and flexibility. USB 3.0 and SATA speeds exceeded expectations, with USB 3.0 being easily used for a boot device. PCIe speeds were as expected from an FX series board. The final OC achieved was what was expected from the processor, though voltage required was somewhat higher than expected.

Reviewer's Opinion

Straight out of the box, the Gigabyte GA-990FXA-UD5 lets you know that it is a serious motherboard design, and one that was executed well. The design is sleek and attractive, with great attention to detail. One may ask what looks matter in a motherboard, but the point is the execution. The parts aren’t flimsy, tolerances are exact and attention to assembly is flawless. That is what makes the Gigabyte GA-990FXA-UD5 so attractive. When you look at it and pick up the GA-990FXA-UD5, you know immediately that you are handling a top quality piece of equipment.

Getting into the board’s features, I was left wanting for nothing, and all of the features worked exactly as advertised. Tri-Sli and three way CrossFire-X are sure to keep gamers happy, as will the much better than average integrated 7.1 audio. Enthusiasts will certainly appreciate the great overclocking headroom and wealth of BIOS options for tweaking. Just about all will appreciate the upgraded USB 3.0, 8 SATA III ports and powered eSATA. And, of course, iPeople will appreciate On/Off Charge to keep their iStuff charged even when the computer is off. The Gigabyte GA-990FXA-UD5 is a feature rich board that should satisfy the needs of anyone planning on using less than four video cards.

Aside from the obvious, there were some really pleasant surprises that came with the GA-990FXA-UD5. The included Easy Tune 6 software is a truly nice program for novice overclockers to get their feet wet with. I was impressed with the one click OC achieved, which was only a few ticks off from what I could achieve when keeping the voltages in what AMD considers a safe zone. More than that, it enables you to see the changes made, enabling a novice to begin getting an understanding of what is going on, rather than having the Wizard of OZ behind a curtain. Kudos to Gigabyte for pairing this with the GA-990FXA-UD5 that clocks well to begin with.

The other nice surprise was increased read and write speeds on the GA-990FXA-UD5 from my 890 boards. Read speeds in HD Tune jumped a full 10MB/s from 92 to 102 with no change in any hardware excepting the MB. This was totally unexpected, as no mention of a tweak to this was made.

The one and only downside was the extra voltage I needed to put into the 980BE to get to 4.4GHz in the GA-990FXA-UD5. It took 1.52v to get the chip stable. Previously this mark had been achieved at 1.475v on other 790 and 890 boards. The jump in voltage also brought with it the natural jump in temperatures, both to the CPU and system. Temps were not out of control, but a little warmer than I would have liked to have seen.

There is no disputing that the Gigabyte GA-990FXA-UD5 is an absolute top of the line motherboard. The GA-990FXA-UD5 is packed with features, all of which work absolutely flawlessly. Build on the GA-990FXA-UD5 is solid, with great finish and attention to detail. The included Easy Tune 6 utility works extremely well as an overclocking utility for the novice, as well as being a very capable hardware monitor and fan speed controller. With the Gigabyte GA-990FXA-UD5, you get an extremely capable and feature rich motherboard, all wrapped in one very attractive sleek black package. The GA-990FXA-UD5 is highly recommended.
