I'm building my new PC, and ran into a a rather iffy question... I can get either 3 or 4 GBs of RAM for about the same price. I'll be running 32-bit OSs for a few months, so I know only about 3 gigs will be recognised nyways; this is irrelevant because I'll be moving to Vista 64 within about 6 months or so. My question is this...if I have 4 GBs of RAM (4x1GB), will dual-channeling still work for the second pair even if the second stick isn't being recognised by the OS? Would I actually get better performance out of just buying 3 GBs?
