Hey sorry about the rough welcome. We are always glad to see new people around here.
I have the Mushkin Enhanced PC2400 Cas2 DDR and it has been great so far. I have run it up to 185 FSB cas2.5. I have been able to run it up to 160 FSB with all the fastest timings. If I unlock my chip I think I can go further without the ram causig problems. If I remember right the PC2100 rated 222 was a little better for overclocking than mine. Go for either the PC2100 222 or PC2400 233.
