No 990fx, but if choosing for example this one http://www.newegg.com/Product/Product.aspx?Item=N82E16813131942
It does support the CPU starting with the 1401 BIOS version.
FX-8350(FD8350FRW8KHK,4.0GHz,8C,125W,rev.C0,AM3+) ALL 1401
Supposing the BIOS on the board is older. You can order a BIOS chip and replace the board's one.
Ah I didn't find that board when I searched. Must be because of it saying uatx instead of matx.
I'll check with Newegg to see what bios version comes on the board. I've had to do that in the past. If its 1401 or higher I guess that will work. If not, I could probably just buy a used sempron processor on ebay for next to nothing and flash the bios myself lol.
I don't know who comes up with the names for motherboards, but it sure would be a lot easier to research them if they had names that weren't seemingly random numbers and letters lol.
I'll give that board a try, thanks
