which memory is compatible with this motherboard?

I have run PC2100, PC2700, PC3200, and PC3200 on this board. It kind of depends which CPU you are using to know what kind of multiplyer you are dealing with, and how much you want to try and overclock it. You can select 266,320, or 400 mhz that you want the ram to run at. You get best performance with PC3200 and lower latency gives better performance also. I used some Corsair PC3200 Low Latency with good results on a Pent 4, 2.8ghz and overclocked it to 3360mhz on air very easily.
My Sons Pent 2.8 is running right now on 2 sticks of PC2100 in Dual Data mode just because we were low on good ram. It still runs perfectly stable just no overclocking now. Good luck
