Make sure you use DDR, if you use PC133 you may be stuck at 100MHZ.
Mind you, I have an older version (at least 1 1/2 years old now).
I stuck some DDR in, and it ran 133MHZ fine. But freezes when attempting to run 133 with PC133.
Other then that, the board runs OK. Hard to get upset with it, when they are so cheap....lol
