Great Overclocking Capability, Plenty of SATA ports, USB 3.0, 12+2 Power Phase


A large video card installed in the bottom PCIe slot might block some of the lower ports (but is a rare occurrence)

990FX Chipset

The 990FX looks very similar to its predecessor, the 890FX. There are no new innovations to the chipset to speak of, but if you look closely, the HyperTransport 3.0 processor link gets upgraded to version 3.1. It now has 6.4 GT/s of bandwidth on the 990FX. There are no changes to the silicon but perhaps the Hypertransport speed may be improved with the additional bandwidth. The Northbridge is a PCI Express 2.0 switch with 42 lanes of connectivity and the 990FX now supports Nvidia GeForce cards (though not all motherboard models will feature this). This is a welcome sight, seeing AMD users were pretty much stuck with AMD/ATI graphic cards for some time.


The SB950 Southbridge offers additional PCI express lanes and all 6 of the serial ATA ports use 6Gbps of connectivity. The USB ports still feature USB 2.0 as the next generation has not been embraced, as the I/O blocks have not changed either. Folks, there really is no cutting edge differences on both the 990FX and SB950.

While the 990FX is only one of the 9 series chipsets, let’s take a look here at the entire 9 Series line up. One item we would like to touch on a little more here is that AMD suggests the new Vishera series should be used with its 9 series line up. Some motherboard partners with AMD have been rumored to release BIOS updates on the 8 series chipsets that will work with this series. However, it’s not recommended by AMD and they strongly suggest that, in order to take full advantage of this new update, we should use the 9 series chipsets.

Now that you have taken a look at what the 990FX chipset has to offer, let’s take a look at the motherboard.

    Excellent review, good sir. Your review pretty much solely made me purchase this motherboard, and I absolutely love it.


    did you have to do anything to get the memory to work at that speed i have 16gb of the same ram 4x4gb and cannot get 1866 only 1600 with the xmp profile or set to auto, i am using the fx959 so dont know if thats the issue but amd says it supports 1866. voltage is right at 1.5v did try to up it a bit and best result was 1.6 got as far as the color boxs animation booting into windows.

    dunno if this helps

    asrock ext9
    amd fx9590 cpu
    16gb as 4x4gb Crucial Ballistix Tactical blt4g3d1869dt1txoceu all 4 match
    kingstone 128 ssdevga sc gtx970
    corsair hx850 psu

    nothing else attached atm not even an optical drive as i use usb sticks if a want to install windows.


      and on topic this is indeed an awesome board , asrock have come a long way and are no doubt ahead of asus and gigabyte now, the reason i say this is i have gone from 990fx ud5 gigabyte which this and ud3 both have vram issues and throttle cpu’s , asus is just awful at the bios stage never mind anything else their uefi driver compatibility leaves looking at any lists a guessing game tbh. the asrock bios is great to setup the uefi drivers are awesome , the only board that can fully support fx9590 , i am totaly in love with this board

      Sometimes you need to go in and manually set the timings for the memory to function at its rated speed. Also the 990FX chipset can act funny when it comes to 4 sticks of memory. I had the UD5 with 4x4Gb Corsair Dominator Platinums and couldnt get them higher than 1600. Would not even boot properly. I replaced them with 2x8GB Hyper Predators and got 2400mhz overclocked and 2133 at stock. Try manual settings first, if that fails pull 2 of the sticks and try agian. if it works than you need to invest in a 2x8GB kit.


    Do not buy from Asrock. You will be on your own.

    I bought an Extreme9 just before Christmas 2015. Went to raid my
    2 Crucial 512gb SSDs and computer would not see them. Called Asrock tech and
    they told me certain makes of SSDs are not compatible with Extreme9 boards. I
    explained that SSDs were much older and Asrock board should be backwards
    compatable. He gave me a short list of drives that were compatible and said I’d
    have to buy new drives. Asrock took no responsibility and were in no way


    my mobo burnt out last week. there is no mention of warranty length on these. I was 18 da over on warranty period. load of rubbish.
