I believe you mean 1066MHz FSB. If you want to use the C2Q with a 1333MHz FSB, you need to buy a motherboard that supports it.I'm looking to buy a new motherboard. Now if it's top listed FSB is 1033Mhz, and I want to use an intel core 2 Quad with an FSB of 1333Mhz, will it work with such a motherboard?
