can I run both or is it better to sick with one or the other? Both duel channel
I just upgraded from 1gig of ram (2/512)and purchased 2 more 512mbs sticks for total of 2gigs of ram. Dell told me (im under warranty) to use matching memory sticks. It can't hurt anything, I wud install all 4 sticks and if it works good for u and if not pull one set out. But how u install them is important. Don't put matching sticks next to one another. Put 1 type in first slot then other type in second slot and repeat the same thing again and they shud work fine. If not use the better of the two sets. With both sets installed ur ram will be as fast as the slowest set and 533mhz is still fast. U won't notice any diff. in speed but u will have double the ram.
