DDR v DDR2.

Is there a big increase in speed from just going from 2GB PC-3200 400MHz DDR to 2GB PC-6400 800MHz DDR2, using a P4 630 @ 3ghz?

If you're running each at its rated speed, yes there'd be a large increase in bandwidth.

Would I notice this in games, as a big increase in fps?

Thanks.

I`m interested in this question too being on a skt 939 rig with 2gig 3500ll pros which are nippy.
I think early comparisons rated real world difference about 7%,couldn`t find anything more recent.
I imagine your biggest boost would be in a new intel based rig with good ram and a better gfx card.

I doubt you'd see much increase in the speed of everyday tasks or games. Perhaps you would in some apps that are extremely memory bandwidth-bound like some Folding@Home cores, but not in your run-of-the-mill games.

Going from DDR to DDR2 probably means a new mobo. Get one with C2D support and treat yourself to an E2180 and see a MASSIVE improvement in performance for a relatively small sum.

if your on socket 939 tight timings and a 1t command rate is your best bet.

Thanks all.
