Summary: I'm not overly impressed with the EFI bios but all boards have them now. The sound is fairly good. Psu is 850w seasonic and the mobo is a direct swap out of MA790X-UD4 which had stable cpu volts so I don't believe the cpu volt fluctuation is connected to the psu. I'd give it a 3 1/2 star but can't so it'll get a 3 based on it isn't getting a 4 even with a $105 sticker price.
Pros: Sata 3/ USB 3.0 / PCIE 16 on 2 slots hence FX.
Cons: CPU voltage seems to me a little erratic fluctuating from 1.3xv to 1.42x volts stock clocks 965BE.
Summary: Out of box only the two USB 3.0 ports worked with the Ubuntu default drivers. I never did get the network working, even after trying the multitude of forum postings. I believe something has been changed in this rev 3 version that has broken what was working for the older revs. I eventually returned the board and purchased an Asus M5A99X Evo R2.0 instead which Ubuntu installed perfectly on the first try. If you want it for windows, it is great.
Pros: Nice Looking board. Windows 7 installed easily but needed driver disk to get everything up and running. Default Windows drivers were just barely enough to get it setup to allow the install of the driver disk.
Cons: Will not work with Ubuntu 12.04 or 12.10 (64 bit). I did not try 32 bit. I did not try an older Ubuntu. Tried for almost two weeks to get the network card working with no success in Ubuntu.
Summary: 3 words... Loading Operating System. I seriously don't know what is with this board, but ever since I installed a RAID array, it would always, and I mean every time I booted it, get stuck at the black screen that says "Loading Operating System". So I tried clearing my RAID array, and CMOS, but to no avail. It just gets stuck that black screen. Tried running with no SATA ports plugged in, and it still goes to that screen, even though there's no OS to load.
Pros: Easy to navigate BIOS, Clear CMOS pins for easy clearing of CMOS
Cons: Refuses to boot, POST almost always goes too fast to access BIOS, BIOS Q-Flash won't read anything off my properly-formatted USB
Summary: This motherboard has brought me nothing but trouble. I guess its just mine its great for the money and it has great features but it wont let me choose boot drives and stuff. It's terrible. I cant wait to go to asus.
