Dual Channel Memory Question

Hey guys,

I am going to be getting 1 more gb of ram on one of my machines. It already has 1gb Dual Channel 2 x 512 in it.

Could I get a single 1gb chip or do I have to get another 2 chips of 2 x 512? Would there be any difference going either way?

Thanks

Thanks for standin' still!

Not really.
I would suggest ditching your current ram and getting 4gigs, just for show.
Newegg has some for 80.

Recent Intel chipsets have the ability to run memory in mixed dual/single channel mode (you could have one dual channel pair, and a single 3rd chip, and the latter wouldn't force the former to run in single-channel mode). You could then add a 1GB chip and your first 1GB would still run in dual-channel, though obviously the new 1GB wouldn't.

If you want your new RAM to run in dual-channel (and your old RAM too, if you don't have an Intel chipset mobo), you'll need two sticks. Rather than spending ~$25 to get two 512MB chips, though, you'd be better off spending ~$40 to get two 1GB chips. Then you could run 3GB of dual-channel RAM, with your existing 2x512MB pair and a new 2x1GB pair. 512MB chips just aren't a whole lot cheaper than 1GB chips are now.
