Gigabyte 990FXA-UD3

Three AMD 990FX-Based Motherboards For Enthusiasts
By

For $5 less than its competition from Asus, Gigabyte’s 990FXA-UD3 provides similar hardware features. The firm loses the rarely-needed but somewhat-pricy USB Flashback processor, and instead adds a somewhat-outdated but less-costly FireWire controller.

Gigabyte doesn’t place one of its internal SATA ports on the upper half of the board to ease front-panel eSATA cable access, but instead puts both eSATA ports on the rear I/O panel. Buyers get the same total number of SATA ports, the same total number of USB 3.0 ports, and the same total number of USB 2.0 ports on both Gigabyte and Asus products (though only Asus claims UASP support under Windows 7).

Both similarly-priced, competing products offer the same PCIe x16 slot configuration, as both are designed primarily for two-way SLI. Both primary slots are permanently connected to 16 pathways each, and both secondary slots are permanently connected to four pathways each. Gigabyte adds an x1 slot above the top x16 slot, however, and uses a cut-away northbridge sink to allow installation of longer expansion cards in this location.

Gigabyte moves its CPU power connector behind the voltage regulator sink and turns it sideways, which could be a benefit or detriment, depending on case and cooler configurations. The latch on Asus’ top-edge connector faces upward, making it hard to reach in cases that rout its cable over the top edge of the motherboard tray, while Gigabyte’s alternative placement could be boxed in by rear-panel liquid cooling radiators, such as the Enermax ELC120 and Zalman LQ-320.

The 990FXA-UD3’s front-panel audio connector is found in the bottom-rear corner, where we're accustomed to finding it. But some cases occasionally enter the market with a cable that’s around half of an inch too short to reach that corner. Older cases might also have hard drive cages that block cable access to the forward-facing SATA ports. On the other hand, while a video card in the bottom slot might also block access to the front-panel USB 3.0 header, that problem is mostly theoretical on a board not practically designed for three-way CrossFire or SLI.

Four SATA cables, a single SLI bridge, and a case badge put Gigabyte’s 990FXA-UD3 installation kit on-par with its closest competitor, though the ends of Gigabyte’s cables are black. The badge might just be more important than the color of the cables, as it indicates that this board ships with Dolby Home Theater software. The software adds on-the-fly Dolby 5.1 digital encoding, multi-channel synthesized expansion, environmental correction, and various other audio manipulation technologies.

    Glad to see AMD getting some love.

    "if we diminished most of those power differences by not installing Asus' power management software at default settings, the company would have likely matched the performance of Gigabyte and ASRock."


    Don't speculate! Do the tests and add it to the article so we can see what the software packages are actually accomplishing! That's why I read your site, yeah? For hard info that I can't get myself.

    990FX is AMD's current "high-end" chipset for enthusiast-level desktops. AMD occasionally releases new chips (look last fall) and motherboard companies keep updating their selection of products.

    Old chipset, recent boards, any questions?

    I totally agree with this statement. The test should have been done and added into the article because this would of been a good representative of the value of the software. I would like to know for a fact if the software was a hindrance to the electrical efficiency of the Asus and Gigabye boards.

    At least the power was measured and mentioned, even if it didn't get into the chart.

    AMD's 890FX was an excellent low-cost server platform, in its day. Great I/O, tons of PCIe lanes, 6-channel SATA3, and ECC support. All with boards and CPUs in the desktop price range that were close to being performance competitive with Intel (when they were introduced, at least).

    Now, AMD is just slipping too far behind. Not just on the CPU front, but like how about some PCIe 3?

    I'm waiting for 64-bit ARMs to hit the desktop. That's probably the next truly interesting thing on the horizon.

    Yes, but not a lot of new things need to be offered anyways. PCIe 3.0 is just a gimmick and doesn't really give much more performance over PCIe2

    What did I miss? The ASRock has better features, including 3-way SLI, more USB3.0, an abundance of accessories, uses less power (the only positive efficiency), has higher performance, lower VRM temps; but BOTH of the other two got awards? I noted the comment about fluctuating prices, but on features alone ASRock looks like the winner. Surely it wasn't the slightly lower OC...

    darkchazz"Three AMD 990FX-Based Motherboards For Enthusiasts"I don't think enthusiasts would want to buy a slow CPU from AMD.

    I think of enthusiasts as people interested in getting the maximum performance from their hardware; regardless of its base level, getting the most out of it. Boards like these which can be tweaked every which way are precisely the kinds of products enthusiasts enjoy.

    Saddest part about the platform is that it feels old and out of date. So little integration... This design is now years old and its their top of the lane. I see nothing new since 890.

    I disagree, the whole platform smells of too much power consumption. AMD needs to INNOVATE, not just add more features and drive up power.

    I disagree again. Sure the HT is old, but except for a few details, this boards, being updated regularly with their firmwares or even the pcb revisions, are quite good. The power modulation works fine for this quite cheap boards, I mean, check out those overclocks, and they are very conservative. The amount of sata3 ports is excellent, PCI lanes are ok just what you need nothing more nothing less. RAM management seems a bit old, you are correct, but only professionals get value of it, professionals that should be buying extreme Intel setups. For the average Joe editing and rendering, their memory solution is just 1 minute slower, who cares.

    I think AMD doesn't need to innovate, which is quite a prostituted word. They need to improve their technologies further, as they've been doing for the last years, just at a faster pace, without falling into self indulgence, in that i agree with you.

    It is nice to see my GA-990FXA-UD3 win a Tom's award (even if it is an older rev).

    My only complaint about the board is that the NB or SB, I don't exactly remember which, would cause a thermal shutdown while running Folding@Home 24/7 last summer. It didn't help that a GTX 560 Ti at 100% load was dumping waste heat right on top of it.

    Re-configuring the cooling in my cheap case and down-clocking the GPU got me back up and running.

    I love Asus's power management options, power savings or performance when needed. Although I wish the balanced setting didn't cause problems with OCing and would pile on the juice when needed.

    lilcinw, my friend had a similar problem. 2 ways to solve it:

    1. move the GPU down to the second slot, which should drop NB temps by about 5-7 degrees C.

    2. Replace the northbridge cooling solution with an active fan (10-15 degree drop). VRMs also get super-hot, 75C is not uncommon under load. Quite frankly, the NB/VRM colling solution on this board is terrible, and I cannot fathom how it got a recommendation at all given these grievances.

    I have that same Gigabyte board but an older version of it without the UEFI - it still holds up very well even after a CPU upgrade.

    I was left wondering the same thing.
