Gigabyte GA-990FXA-UD7


Testing and Results

To test the motherboard I usually present a typical set of benchmarks which have proven their worth over time. Today it’s a bit harder, as initially the motherboard I wanted to compare the UD7 with is the Gigabyte GA-785GMT-UD2H, which easily allows 4-core unlocking, and so I took quad core results. With the core unlocking issue from the UD7 results have gotten a bit messed up and in fact, the UD2H would easily win considering it’s core advantage. Plus to that SiSoft Sandra decided to put throw in the towel just before the deadline of this review. Whenever possible I will update this review, also in regard to the current outstanding issues.

All results are taken with a Phenom II X3 3.80GHz. Memory DDR3-1600 CL6-8-6-20 T1.

AIDA64 Memory


785GMT: 43.7ns
990FXA: 43.4ns



785GMT: 112.8 MB/s
990FXA: 140.8 MB/s


All results speak for the UD7. Important to note is that on standard HTT the UD2H overclocks to 201 HTT, which gives a typical advantage in benchmarks. Even then, the UD7 runs off with the performance crown. If only it could unlock that CPU…

Pricing and Availability

The Gigabyte GA-990FXA-UD7 is widely available in any country that sells computer hardware. Prices start at around €190.- and range up to €240.-. The UD3 and UD5 siblings come for respectively €115.- and €150.-. The ASUS Crosshair V Formula comes for about €10.- less than the UD7 and is good competition.

    7/10 you must be joking.
    Voltage droop issue, Core unlocking issue and expensive.

    on top of that one miserable usb 3.0 controller for the front, same for the back.
    is this a mb for the future?
    well, not for me.

      Hi Zeepkist,

      I’m not joking at all. In my eyes 7/10 for a flagship motherboard is a bad score. These top-of-the-line motherboards are supposed to take the crown, regardless of their price. In this case the price barely justifies the quality of the motherboard.

      If the motherboard didn’t have the Vdroop and core unlocking issue it would have had a much better score. It’s up to Gigabyte to fix these problems, or at least show that the Vdroop is essential for the upcoming Zambezi.

    i would give it 4/10.

    too many usb 2.0 and not enough usb 3.0

      You use USB 3 for what exactly?
