Three AMD 990FX-Based Motherboards For Enthusiasts

AMD’s flagship FX-series processors squarely target enthusiasts with sub-$1,000 system budgets, and it's hard to get there with an expensive motherboard. We requested every vendor's top-value solution, and received three boards for your consideration.

990FXA-UD3 Software

Though the 990FXA-UD3 includes a variety of freeware and trial software, EasyTune6 is the focus of today’s discussion. That’s because its settings are unique to each motherboard.

The first two EasyTune6 menus cover hardware monitoring and reporting, with an interface that’s similar to CPU-Z but with slightly more detail. We can, for example, see all eight DRAM configuration settings on a ten-slot menu, where CPU-Z would limit us to four.

Gigabyte’s fan controls are fairly simple and somewhat limited, similar to what’s long been available in Gigabyte’s firmware.

Gigabyte’s HW Monitor menus track voltage changes and provide user-configurable alerts for temperature and fan monitors.

CPU reference clock and ratio settings are easily adjusted, while memory frequency adjustments aren’t as easy. Since memory ratio adjustments require a reboot, I suggest manipulating them exclusively through firmware.

Like reference clock and CPU ratios, the functionality for EasyTune6’s CPU core voltage changes can be verified through third-party programs, such as CPU-Z. A voltage meter was needed to verify the effectiveness of DRAM voltage adjustments.

    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.

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.

    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.

    Aren't the 990FX chipsets kind old?

    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

    falchardAren't the 990FX chipsets kind old?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 don't think enthusiasts would want to buy a slow CPU from AMD.

    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...
