i also noticed those specs when i bought my board, but if you look around the forums here, you'll find hundreds of people running CPUs @ 1GHz and over on the CUSL2 (most of them OCed of course). but whether you are running a P3 1GHz or OCing a P3 700 to 1GHZ shouldnt matter...once a CPU is overclocked, any benchmarking program will clock it at its OCed speed, not its default speed. unless something in the BIOS recognizes a CPU as a 700 OCed to 1GHZ, and not a P3 1GHZ, it should run fine. the fact of the matter is that many people buy the CUSL2 for its amazing quality and stability, and the CPU speeds that many people achieve with this mobo are 1GHz and well over, whether it is an OCed CPU or a CPU @ default 1GHz.
