Hey, Whats the difference between 128MB Mushkin High Perf REV2 PC133 222....... and ...... 128MB Mushkin High Perf REV1.5 PC133 222? Both of these are on their site. I am going to purchase some for my new system im building and wanna make sure to get the correct 1. The brd is a MSI 6337 512K max 3 dimm sdram brd.

Plus, whats the CAS3 and CAS2 i hear about? I imagine the cas3 is faster,but is there that much difference?
Thanks!

CAS2 is faster because it's a latency (delay)
It's enough faster to want CAS2 if you can get it, memory is horribly slow compared to CPUs right now...

I'm not sure about the difference between Rev 1.5 and Rev 2 though.

i'm not really sure about the 1.5 vs 2.0 either, but i have a stick of rev2, it's been tested and ll the tech sites rave about it... i'm running mine at cas 2-2-2 fsb 154, and it's totally stable... and it's only $139 right now so IMHO it's really worth it...
