It's not so much the board, but the CPU you put onto it. I believe it to be a 12* multiplier(but that's CPU controlled), and 266MHz FSB (I believe EPoX Tech over at AOA had one running at 206MHz, or there abouts
Depending on the system setup, a low multiplier and a high FSB setup is the most commonplace, assuming you have an unlocked CPU, but as with any other science, I live and play by the "Try it and see" approach.............currently with a result I am happy with
