I recently bought some RAM that's CAS 3. The (older) BIOS on my motherboard only supports settings for CAS 2 and CAS 2.5 (as I found-out AFTER I had bought the new RAM ... sheesh.)
I'm having goofy, inconsistant problems installing XP on this system, and thought this might be the culprit (though I've run MEMTEST86 a few times with no errors ...)
Thanks for your help!
