I don't know if this is the right place to ask a question of Crucial, or if it's only for users, but here goes. I have a Dell Latitude D610 laptop, with 2 slots but only 1 DIMM, 1GB, PC2-6400 (800MHz). The Dell site recommends filling the second slot with the same, which is available there. But the Crucial memory adviser recommends filling the second slot with a PC2-5300 (667 MHz), part# CT492732. I'd rather stick with the PC-6400. Searching for memory by characteristics rather than by the computer type, I come up with part# CT 12864AC800 for the PC2-6400 and part# CT12864AC667 for the PC2-5300. Hmm - two different part numbers for the PC-5300? Are they the same unit? (They seem to have identical specs.) If so, then the other one (in blue) should work for me. Correct? Thanks.
