Morning all. I want to upgrade my newer Vista laptop from 1GB to 2GB RAM but I have a question. If ordering through Toshiba I'm looking at $100. But ordering elsewhere like at Crucial.com, which I think is reliable, I'm looking at $60 for seemingly the exact same thing. If the basic specs are the same, "1GB PC2-4200 DDR2-533MHz", should it be okay ordering from other retailers? Toshiba <- One 1GB stick for $50 Crucial <- Two 1GB sticks for $60 Other confusing things that I've pretty much figured out are that I should prefer non-ECC and that there is no huge difference between 533MHz and 667MHz. Other than that, I really have no clue and am probably making more out if than I should. Thanks.
