Recieved my new 2.8C M0 SL6Z5 and as of right now, she is burning in at default vcore and running at 250 fsb (3.5ghz). Will let it run here for a few days than maybe try taking her up more. Before anyone asks, I ordered this from the UK and had it shipped here. Paid $280 with shipping, but oh well! It worked out! I went through about 3 2.8C's that wouldn't do 250 and about 5-6 2.6C's that wouldn't do it either!
