My BE can use volts above 1.325 at least. Anything more than that on this phenom causes it to not boot. I think I just got it stable on 255htt though, gonna make it run a few benches first though. If it even runs 270, if it even boots, then there will be an improvement over running it on air. I just hope the B3's are a bit more tolerant than these B2's I'm testing with.
