As an example, I have an extra G.SKILL 1GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Desktop Memory, the condition is new but I do not need it for my computer already has 3gb of memory and I am on windows xp, and the extra gig (4gb) does not improve anything that I have noticed and windows would only recognized 3.25 due to the xp limitations.

What I would like to get would be CORSAIR ValueSelect 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Dual Channel Kit Desktop Memory. I have a friend with a Dell computer is a need for memory. I know this memory would work for his computer because I have the same memory in my kids computer.
