In prepartion for switching from dial-up to cable I need to increase my memory. I am embarrased to say I only have 32 mb of memory ( I'm limping along with this computer for a couple more months then I'll be on to new and better things) In the meantime, I need to have at least 64 mb of RAM. According to Belarc I have 4 slots available, only 2 slots are in use right now with 16 mb each. Does it matter if I replace the 2 - 16 mbs with 32 mb each or should I leave the 2 in there and just add an additonal 2 slots with 16mbs each? If there's no difference in perfomance I'd probably buy te 2 16's assuming they'd be less expensive than 2 - 32's
