After each reboot board become more and more unstable. After returning to previously stable settings, it's still unstable. Shutting down and cold booting make it become stable again.
DFI has one option to choose if board should cold boot after each BIOS change and save, but didn't found with GB. Is there any? Seems like it does a cold reboot after changing voltage options from auto to manual and vice versa.
I have experienced this as well, particularly with memory timing adjustments.

I don't believe there to be a cold boot option, I've only seen that on DFI boards (socket 775)
