Arrgh! Dell tech support chat tells me I can take 1 gig max memory. They linked me to a Dell page that says I can take 2 gig, with 1 gig per slot for the 533 FSB. Crucial's "configurator" says 1 gig max, 512 per slot, (for the 533 FSB, 2 gig for 400) as does Kingston's sight.
Who should I believe?
Would my DxDiag tell me which FSB I've got?
