Supposed to run at low voltage? It's running 3.3Ghz but only .960V. That aside, I bought this CPU from MC's, but I believe the CPU was used (return???). The HS already has the thermal past flatted out. The seal was somewhat peeled a little at a corner when I got it. Gonna see if it's stable. If not, maybe that's the reason it was returned. But the returner was careful enough to not mess up the seal. Treacherous!
