Summary: There are plenty of forums online reporting this problem and there doesn't seem to be a clear fix anywhere. Anywhere from 10-50% of the time, it won't return from sleep (S3) or reboot properly (Windows 8 64-bit). Requires turning off the power supply, pressing the power button to empty the capacitors, turning on the power supply and starting it up again. It's frustrating.
Summary: this mother board sucks.. would not let me get into bios.. tried everything.. removing battery.. different video card.. different ram.. multiple keyboards... wasted my time putting everything together. needed this computer to work ASAP and it wouldnt...
Summary: I stumbled upon a 2011 CPU, and rather than sell it I figured I would build a machine around it. And I know I chose a great board for it, as this board has everything I need as a basis to game, edit video & audio, and otherwise just work and play. Only 4 RAM slots, but still supports quad-channel architecture. Realtek 898 onboard audio is "good enough", and I've read that it's one of the better audio codecs.
Summary: I normally go with Asus motherboards but decided to give Gigabyte a try. This motherboard would not get into bios, menu, etc.. Tried everything, reset by removing battery for 30 sec / all night, tried different keyboards, completely disassembled / reassembled pc and making sure hardware was installed correctly. Only thing I didn't do was flash the bios, but this is a new board right? What a total waste of time!
Summary: The motherboard failed on the first boot, BIOS from the included disk. After extensive testing & subsequent re-attempts with updated BIOS from Gigabyte, it was confirmed that the CMOS was faulty (evidently a common problem with UD3 & UD5 VIA chipset boards). More info was requested by phone on whether or not to return the CPU with the Gigabyte motherboard (kit that included the CPU).
Summary: It works. 3D BIOS looks awesome. I overclocked my 3820 a little bit. Hopefully it lasts long. And the board comes with a lot of cables that are very helpful like the crossfire connection cables for both N cards and A cards.
