To kick things off, I decided I’d try what I’ve always had trouble with on previous boards: booting into Windows at 220bclk. This was done on the box cooler and with minimal tweaking done in the BIOS.
Just to give you an idea, the Core i7 965, a C0 revision processor, was hitting these speeds on LN2 on a good day, while the Core i7 920 D0 revision processor when combined with the EVGA E761 Classified does this all day long. For the price of a 965 you can purchase a Classified and a Xeon w3540 for $609 shipped or an Core i7 950, which will walk all over the Core i7 965. The Classified really unlocked the potential in these Core i7 processors.
Writer’s Note: After completing the overclocking segment I found a guide by Shamino, one of if not the man responsible for the Classified. The guide discusses the various voltage and timing settings that can make the difference between a successful and unsuccessful experience with the Classified.
