im not really a hardware whiz, and somebody else ordered my ram (the 1 gig) couple of years ago. i ran a scan from crucial.com to see what type of ram my dell dimension 2400 can run. im pretty set with everything except the term "dual channel memory" and DDR2. the scan says that my computer cannot run dual channel memory. does that mean i cannot install DDR2 pieces of ram inside my pc? what does dual channel memory actually mean? and yes i have googled for some time about this, but i cant find satisfactory answers.
