I have a hard time getting my e2160 over 3.2Ghz stable with 1.496 vcore. The newer batches don't seem to oc as well. But, thats just my opinion based on some of the post I have read here in the forums! I had to settle @ 3.15Ghz w/ 1.496vcore to keep it stable. Of course, each Cpu will be different and this is just my experience with this specific Cpu.
