I installed a refurbished Corsair H100 onto my GD-990FXA-UD3 with an FX-8350 last night.
Previously I was running 4.6ghz at 1.35V with an NZXT Respire T20 with very high load line calibration and HWMonitor was reporting 70C running LinX.
After the H100 was installed I got it up to 4.8GHZ at 1.375V and +.25V to the CPU-NB with lower temps than before. It passed 10 iterations of "very high" LinX (4gb) at the same reported temps as before on air. I queued it up for 20 iterations of LinX using 14gb of memory to test stability over night.
I came back an hour later to the comp off and it would refuse to power on. If I hit the power button, it will blip on for a fraction of a section and immediately power off. I removed everything from the case and disconnected anything unnecessary to rule out shorts to no effect. I tried another known good power supply and no change either.
I have tested the video card (Radeon 7970), RAM (4x4gb Crucial DDR1333), and power supply (Seasonic X-650 gold) successfully in another system.
At this point my thoughts are that something blew in the power stage on the motherboard. I bought the board used on craigslist a few months ago so I'm unlikely to be able to get an original invoice for an RMA.
At this point, I'm thinking of just paying through the nose for a 990FX Sabertooth to know I'm getting something of quality. Any other suggestions? I use the box as a VM testbed, folding@home cruncher, video encoder, and as a secong gaming system when a friend comes to visit.

) GA-990FXA-UD3 back from Gigabyte today... I'm very disappointed in Gigabyte after years of using them. I bought the board new about 5 months ago, now I have to live with a refurb. The original board powered on briefly then off, then after another slight pause it booted again... Turned out the 3v ground was bad. It ended up frying my cpu along with the motherboard. I don't overclock and had disabled the "AMD Turbo" whatever it's called that bumps the FX-8350 from 4.0 to 4.2 GHz... Even though this option is enabled by default it can still void your warranty. My solution was I bought an Asus M5A99FX PRO R2.0. I have posted my thoughts on the Gigabyte boards in another thread so i'll just recap here... The Gigabyte boards manufactured in Taiwan years ago were much better quality than the ones now manufactured in China. I would suggest keeping an eye on your hardware with with this Gigabyte board. I've been reading horror stories from people and this motherboard. I wish you the best of luck with your board, as I will be pulling this board out as soon as the replacement comes in... (I will keep this as an emergency spare, but I would not recommend them to anyone ever again.)
