This might be a stupid question but i guess im stupid then when it comes to memory upgrades, but I want to upgrade my laptop memory to 512mb it has 2 slots and it already has 256mb in it. can i keep the 256mb in it and still put in the 512mb or do i have have to remove the 256mb? Anybody know thanks

You can leave the 256 mb dimm in, and add another one.

^what he said. Just make sure the memory card is compatable with your computer.

With very very new laptops (i915GM chipset in particular), some models give higher performance if you use two identical memory modules (for dual-channel support).
