I stumbled across a thread the other day which had atached a run-down of overclocks people have acheived with their C2Ds. I think it was copied from a different website and it contained information such as which cooler had been used and what volts etc. It was split up by each spec of C2D E6300-to-X6800. Anyway, I can't for the life of me find this thread!
