Update: I changed the FSB to 428 so the CPU runs at 3.85 and was still getting lockups and restarts, which scared me because it's never happened before that low. So I then changed the tRFC to 55 and it worked, but now crashes to the desktop in games. I think I'm getting there. I will try upping the voltage from 1.8 to 1.9 (Currently at auto), even though the ram is not being OCed that much (DRR2 800 with 1:1 ratio so only a 56 MHZ increase)
