I have my board set up now and I'm stable at 4GHz / DDR 1113 MHz, however I have an issue.

When I restart the pc from windows, it fails to post, I just get a black screen. It also happens when I go into the bios for a second time and try to alter a setting. After the cmos has been cleared, I can set the 4GHz overclock, and it reboots fine, just anytime after that it wont. Also when I power off the pc & go to turn it on again it wont post. I also noticed when it doesn't post it doesnt cycle the voltage lights like it does while posting normally.

I have tried bioses 0504, 0604, 1307 and they all do it.

Any advice?
