I am currently running what you seen in my sig, but for some reason, when I try to set my memory (newegg link) to 1066 (as it is rated with AM2+) I get some crashes in games (crysis, lock on) and the occasional BSOD. Below is my CPU-Z and as you can see, I should be able to hit 1066, although the highest I can set my tRC timing to is somewhere in the 30s which is probably too tight. Also, my motherboard only allows either 2.080 or 2.155v for the mem, so I can either go under or over the required 2.1v. Those are the only two things I can think, anyone got any other ideas on why I cant stay stable at 1066?
