ASRock 990FX Extreme9 Motherboard Review

To test the ASRock 990FX Extreme9 motherboard, we paired it with an AMD FX-8350 processor and 8GB of 2133MHz memory from Patriot. We will be outlining the ASRock 990FX Extreme9 motherboard’s performance with the AMD FX-8350 CPU at its stock frequency of 4.0GHz and when overclocked to 4.6GHz.

We are also including the performance of a similarly-priced Intel Z77 configuration consisting of an Asus P8Z77-V motherboard and i5 3570K processor.

Both systems are kept as identical as possible to eliminate variables. The only difference between each test system (other than the CPU and motherboard) is the SSD used; this could have an impact on some of the test results.

    Great motherboard, they deserve to be recognised more in the enthusiast sector. I love my ASROCK Z77 board

    Nice look board and excellent overclocks. I want to upgrade my AMD system this year, but have been waiting on the new products.

  • Indloon

    It is a little expensive IMO for what you get, Intel boards start way under £100 today.

    Great board, sexy layout and well featured. BUT as overclocker i feel 1.5v core is just too much, even for AMD CPUs…. The marginal gains that you get from 600mhz for about 0.3 vcore increase is not worth it. For 5.0ghz, is ok, 1.5 vcore would be understable, but going upper than that is just too away from my comfort zone. I dont know if I can blame the board or a bad chip. Good review !

    The Extreme9 990FX will do very well with a 8370E. Does good enough with 9590 (I call the lazy overclockers board combo). Don’t expect it to overclock the 9590 much. It does run all 8 cores at 4.9 ghz all day with turbo turned off (a little better than 4.7/5.0 stock setting for most things). Recognizes the Avexir 2400 speed ram and sets it automatically. Just make sure you have room for a big twin tower air cooler.or a least a 240mm water cooler so you can keep that temps down.
    It does very well with crossfired R9 285s OC to 1100 Mhz (water cooled also).
    If you are going to do something likes need a big case and big power supply too. Like around 1100 watts. 285/380s need a lot more cooling to push them over 1000Mhz
