The newest stepping do seem to be great. I have a 165 CCBWE 0546MPMW, and I'm in the same boat with you guys. I can get to 2.7 stable at 1.425, but one core is bad at 2.9 on 1.5 after 2 hrs, and the other did 12 hrs. last night. I'm going to bump the voltage over 1.5 and try to get to 3.0, just to say that I did it. I'll end up leaving it at 2.7 though. BTW, is CPUZ accurate on voltages? Because it says 1.44 when the BIOS says 1.5. If CPUZ is right, I have enough room to prob go past 3.0, and whoa, would that be sweet. Like having an FX60, I think. You know, someone should write an affinity program that lets you permanently set apps' affinity to a core. That way, I could run games and stuff on the good one and not worry about the bad one.
