yes you can, but you need to use a DDR1->DDR2 adapter. You will also find the only place you can get these is Japan and they aren't cheap. I doubt the shipping costs will be either and you will be running the risk of incompatibilies... It will work out cheaper for you to buy DDR2 memory, or a board that has both types of slots on it. Now, if I could only find an adapter that would let me shove DDR2 into a DDR1 slot...
Bottom line recommendation, buy DDR2 and sell your DDR1. DDR2 is much cheaper than DDR 1 so you will get a big chunk of your cost back by selling your old memory.
