This thing makes CPU unstable if you fail a RAM overclock. High voltage when LLC disabled.

Summary: I had two OC profiles(4.2 and 4.4 ghz) saved in bios and both survived stress test of prime 95 with firestrike(4k) benchmark running for six hours. I had no problems for 3 months. Then I tried to overclock my ram and it failed. So I decided to load the old stable profiles.

Summary: let me pretense this by saying I loved this board for a few weeks before I started having issues with it. this is a fairly nice board for the price point, more than enough peripheral connections, and what not, I dont need to play up the 9990fx if you're here you've looked at the specs.
Summary: I will change rating as I go, "2" for starters. Was hoping getting a good product for the money... will see. Btw, customer service should have a chat option for cases like that, not just email and long waiting phone lines.
Pros: On the paper it's the second best motherboard out there after ASUS Crosshair Solid looking Lots of USB slots, lots of SATA ports
Cons: Starts okay, however I find it has way over-complicated BIOS without proper instructions what to set where & in what circumstances. Could not find too much help online either; few bits of info from tom's hardware, few from over-clocker's etc, but nothing really clearly in user manual (WHERE IT SH...
Summary: Ok, so I took off the plastic coverings on the VRM/NB and SB and attached fans to them. The fan headers burnt out and I lost sound, can't RMA because I modded this board quite a bit, plus I'd rather get an ASUS board next time.
Pros: It works, it's cheaper than some other 990fx boards.
Cons: Ok, first of all don't buy into these 12 phase VRMs. The quality just isn't there, the ASUS 8 phase VRMs are MUCH better, especially when overclocking. Even when you replace the thermal pad on the VRM and NB with some PK1 and attach an 84CFM Tornado 80mm fan to it, you can't reach 5Ghz IBT stable...
Summary: I bought this a couple months ago, and have never been able to get the USB 3.0 to work with my USB 3.0 ext hdd. Ive tried EVERYTHING, checked all the forums and found that I am not the only one with this issue.
Summary: Changing the base clock does not reflect the resulting CPU speed, HT and NB speeds unless you tab to those fields and make a change. It seems to like the preset overclock settings better which does not allow you to change CPU multiplier.
Summary: Couldn't run my memory at its proper speeds (That could also be the fault of the memory though).
Pros: User friendly bios.
Cons: I was on my third 990FX Extreme9 until last Sunday. My computer just shut off in the middle of me browsing the internet. I thought it was my power supply at first but after ordering a new power supply and a couple hours of testing I found out that the heatsink plugin on the motherboard has fried....
Pros: So right out of the box and into the case plugged in and fired up, this board works perfectly with a FX 9590. Handles fan management for the Liquid cooling system that came with the 9590 decent enough with some tweaking in the bios. The AMD RADEON 1866 memory I got along with my order works flawl...
Cons: One of the USB 3.0 Connections was broke and several pins were bent, only noticed this as I was moving some power supply cables around when switching PSU's. I don't use the case 3.0 plugs because the last asrock board I had froze up anytime I tried to use them. So this isn't a loss but a damaged ...
