Gigabyte 990FX-Gaming AM3+ Motherboard Review

We will be outlining the Gigabyte 990FX-Gaming motherboard's performance with an AMD FX 8370 CPU, 16GB of DDR3 memory, and a GTX 980 Ti graphics card.

CPU-installed

Unfortunately we do not have access to comparison data from other AM3+ motherboards. As such, we will highlight the performance gains available by using the Gigabyte 990FX-Gaming motherboard to overclock the FX 8370 CPU.

FX-8370-stock FX-8370-OC

Despite the FX 8370 supporting a maximum Turbo Clock speed of 4.3GHz, Gigabyte's motherboard kept the chip at 4.1GHz using a 20.5x multiplier. This is likely to be a bug related to the motherboard's early BIOS revision, and will have an impact on performance.

The 2400MHz memory profile was loaded from our Corsair Vengeance Pro DDR3, however the board automatically set the kit to 2133MHz instead due to its 10.67x maximum memory multiplier.

  1. Considering you used the new Wraith cooler from AMD, I’m surprised you didn’t include temps on your overclocking page. Maybe AMD told you not to? Kudos for including minimum fps though.

  4. You can see temps over here: http://www.kitguru.net/components/cpu/luke-hill/150-gaming-cpu-amd-fx-8370-w-wraith-vs-intel-core-i5-6400/9/

    The FX 8370 hit around 53C under OC load, but was loud in doing so.

  5. It’s okay, Luke. There’s a reason he’s accusing – oops, I mean suggesting – that you’re shilling for AMD.

    Notice he didn’t have a problem when you didn’t include temps on the reviews of the Asus Maximus VIII Impact ( http://www.kitguru.net/components/motherboard/luke-hill/asus-maximus-viii-impact-z170-motherboard-review/10/ )

    Or the MSI X99A SLI Plus ( http://www.kitguru.net/components/motherboard/luke-hill/msi-x99a-sli-plus-motherboard-review/10/ )

    Or the ASRock Z170 Extreme4 (http://www.kitguru.net/components/motherboard/luke-hill/asrock-z170-extreme4-motherboard-review/9/ )

    Or the MSI Z170A Gaming M7 ( http://www.kitguru.net/components/motherboard/luke-hill/msi-z170a-gaming-m7-motherboard-review/10/ )

    But hey, at least you included them on the Asus Sabertooth Z170 Mark 1, right? Oh, no, wait, that was just motherboard temps. ( http://www.kitguru.net/components/motherboard/luke-hill/asus-sabertooth-z170-mark-1-motherboard-review/12/ )

    But no. Clearly AMD told you not to include temps on this review.

  6. Gigabyte did a great job with the motherboard but how many PCB layers does it come with. In the audio picture there seems to be 2 squares where I normally see the PCB layer count. The USB performance is partly hampered by the OS used in the review. I believe the results would have been very different with windows 8.1 due to native uasp. Good motherboard for all of those looking to upgrade existing AM3+ builds.

  7. I own a MSI 970A SLI KRAIT EDITION, is working well, but i don`t think that is a good idea build AM3+ Motherboard this days, we will have Zen before 2017, i will update

    I have this MB and AMD FX-9590 and I have no complain about cpu-related stability: at stock speed and all power features like C6, c&c, ecc it is really stable: Prime95 stress tests were really good and temperature never went in overheated zone, while other MBs did.

    The really bad, bad, bad issues are BIOS related: system is unable to use some manual settings. The same problem related to multiplier explained in this review occurred in DRAM settings: XMP profile work perhaps, but manual settings are as goods as comments: system doesn’t use manual DRAM voltage settings, I’m not even sure manual timigs are taken into consideration.
    Actually I’m using failsafe ram configuration because of that.

    Any other experience related?

  9. Haha!

  10. Yeah I have been having difficulty trying to overclock RAM. I can run at 1866 but trying for 2133 like in review. Going to try adjusting voltages and try 2 dimms instead of 4. I am using the same CPU as you. My Asus CHVF-Z was much better for RAM oc, but couldn’t fit 2 triple slot cards without blocking the motherboardcase connectors. It was also missing the nice reinforced Pcie slots and the M2 slot that comes with the G1. I’m very happy with it overall. Handles the 220W beast no problem.

  11. Graziano Schrödinger Lenzi

    Gigabyte sent me a beta firmware to help ram issues.
    Fact is, it works, BUT…
    Yeah, to run at 2133 you need to use 2 banks only. This is bad.
    And… I am able to run at 1600 x 4 banks, it is good, but when I set bios at 1866 it still runs at 1600.

    N.B.: related to temperatures, I put a 140 fan running at minimum, perpendicular to VRM heatsink, having air flowing thru heatsink: result is 10°C less in gaming.
    Is was worth the try.

  12. I changed the voltage and took out 2 sticks. Running stable at 2133. I ran 4 sticks with 2 different brands at 1866 no problem, on original bios. Don’t use the xmp profile. Make a custom one.

  13. just picked this MB up for $120 from Newegg +$10 rebate so $113 after rebate and shipping. I hope it gives my comp life until Zen comes out and is settled in..

  14. How did you get the fx 9590 to run on it; my system is a new build and says the cpu is incompatible with the mb?

  15. Graziano Schrödinger Lenzi

    It worked from beginning.
    Or BIOS has to be re-flashed, or CPU is not well mounted.

  16. Thanks Graziano, i’ll give them a try.

  17. I’m looking at doing a water cool loop with this mother board and would love to include the vrm and nb as they get ridiculously hot I find. Is it hard to remove the heatsinks covering those and would you know of any water blocks that would fit? having a near impossible time locating any. Spectacular review as usual!
