I got mine last week and it seems like a great stepping. 1.35v (stock volts) I did 25hour prime stable before I stopped it. I'm going to try 1.4v 2.9ghz soon, I'm running it at 2.9ghz right now so we'll see.
btw I got a CCBBE 0616XPMW, removed the IHS and I'm forced to use the stock hs/f from it til I can figure out a way to mod my blue orb 2 to fit down on it without the IHS.
