I agree with all cautions mentioned above...
...Here is the latest llst I found and my own suggestions/caveats are shown as well.
AMD FX-9590 Compatible Motherboards
That list I suppose includes the motherboards that the motherboard maker has the
FX-9590 shown in the supported cpu list.
However we have users here that stay and help people all the time that have had the
Asus M5A99FX PRO R2.0 and it was very UNstable trying to run an 8 Core FX-8350
beyond 4.5Ghz. So that board would n0t be on my list.
Gigabyte GA-990FXA-UD3 > this motherboard has caused problems for people with
8 Core FX cpu throttling in revisions of the board after Rev 1.2. Would n0t be on my
list for sure.
Gigabyte GA-990FXA-UD5 > this motherboard has caused problems for people with
8 Core FX cpu throttling in revisions of the board after Rev 1.1. Would n0t be on my
list for sure.
Gigabyte GA-990FXA-UD7 > There is a new Rev 3.0 of this mobo and most likely board
in the retail market now. The Rev 3.0 of the other versions of UDx were real pains for
the users with the Rev 3.0, so for that reason I would certainly have my suspicions
about the UD7.
MSI 990FXA-GD80V2 This board is said to be okay with the FX-9590 in use. We have
not seen any of this motherboard in the AMD Cpu or AMD motherboard forum sections
so no real idea if the board works well or not.
That really only leaves a short list for sure. If I were going to get an FX-9590 (am not
since I have FX-8350 that is P95 blend stable at 5.2Ghz), my choices would be narrowed
down to the > ASRock 990FX Extreme9 >> Asus Crosshair V Formula-Z >> Asus
Sabertooth 990FX R2.0.
That is a short list indeed of motherboards that experience has
shown would do well in trying to overclock an FX-9590, but with a shedload of cooling.
CM 212 air cooling is not likely to work very well at all since by experience those of us
in here that do push to 5.0Ghz and beyond with all cores enabled...well we all have had
to go to very stout DIY watercooling setups.
