I have CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory. Im wanting to add more memory and since windows cant use a full 4GB I thought I would buy this...

which is 2X512 CORSAIR..

my question is, is it ok to have 2X1GB in 2 slots of 2X512MB in the other 2??? or do I need 2X1GB in all four slots?

I would just buy another 2X1GB but if windows wont see it i figured it would be a waste
