DDR3

What is the difference between DDR2 and DDR3 RAM? Becasue I saw DDR3 RAM and was wondering if it really is much better than DDR2.

It uses a different DIMM-internal design and some modest differences in DIMM-external signalling. It's not compatible with DDR2, so you'll have to have a new MB that supports DDR3 to use it. Its speed grades will start where DDR2 is topping out, in the 800-1066MHz effective data rate area, and go higher. Since Intel CPU FSBs are the current bottleneck on memory, it's not likely to come into general use for another year or so at least.

^What he said

And no, for right now it's probably slower than DDR2 because the timings are worse, and current chipsets can't utilize the extra bandwidth, so it'll be slower if anything, plus it's ridiculously expensive, so not a good buy for right now.

All this talk of DDR3 lately and I'm still on DDR1

Thanks for the help. i was just curious

Anandtech recently had a great article that I think would answer the question quite succinctly. Its on the front page right now.
