4GB of RAM

[Leviathan41]

I'm getting ready to build a new PC and was wondering about using 4GB or RAM. If I understand right, I will need a 64-bit edition of XP or Vista to have all 4GB used, is this correct? Also, should I go with 2x2GB sticks or 4x1GB sticks, are there any pros/cons for either setup? FYI, I am planning on a Q6600 and an Asus P5B motherboard. Any known issues with this setup and 4GB or RAM? Thanks! :D

Sixty four bit OS is needed and you're better with 2 x 2GB sticks rather than 4 x 1gb: Better OC potential and less to go bad.

But if a set goes bad he wont be computerless waiting for rma.
