So Windows 7 is even better at using multiple cores. I also noticed a big difference in time with wPrime on 1024k mode, about 10 seconds difference between vista and 7, and then another 5 seconds for the increase I had in clock speed. Right now the cpu is at 4.08 and nb at 2.8. 270htt is too much for my chip so I switched over to the 16x and 11x multis to go higher.

Edit: 1E should be 1.35v because thats stock voltage.
