So, this new processor batch# 3049A355 absolutely sucks! Last night I had it running 4.6 @ 1.36v. Played C.O.D all night. No problems. This morning I went to fire up the computer, and just got the blinking cursor. So, after playing with it for over an hour, I can get it stable at 4.2 using 1.32 v. But anything higher, I get the blinking cursor. Now is it a poor cpu, or is my mobo killing these chips? All other voltages have be let at auto.
