Is this RAM compatible with my system?
I'm going to upgrade my Dell XPS 420's RAM (Computer memory upgrades for Dell XPS 420 Desktop/PC from Crucial.com) from 3 gigs (2x1GB & 2x512MB) to 8 gigs. Will two kits of Newegg.com - AllComponents 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model AC2/800X64/4096-KIT work even though it is a dual channel kit? Also, according to the Crucial website this is the fastest RAM my motherboard can use, is this correct?
