Synergetic RAM......?

[aflaba]

I have a Dell laptop that came with 2 x 512 MB RAM. I'd like to bump that to 2 x 1 GB. But from what I've read here on these forums the two memories work together and stuff. And that seems to be important.

If I get two 1 GB memories called "1024MB SODIMM DDR2 200pin PC5300, 667MHz", is that good? Or are there other types that work better together?

Thanks!

Dell has an upgrade center on their site, input your model and they'll tell you what you need. There are probably only 2 RAM slots in their laptops so you'll need to buy 2 new 1GB chips since they require matched pairs.

bishop, i need a new pc with 2 gigs of ram and i would say about a 2.0 to 3.0 ghrtz processer. running xp home, no monitor needed. any ideas on good deals? i configured one at dell for $750 you think i can find one cheaper?

What I was asking was if those 2 x 1 GB RAMs will work well, or if there is some better kind.

Also, how much faster will my RAM become when I get "1 GB + 1 GB" compared to "1 GB + 512 MB"? Will it get more than 33% faster/bigger?
