I just pulled a Crucial 1GB 184-PIN UNBUFF DIMM 128MX6 and a Samsung 256MB DDR PC2700 CL2.5 stick out of an old computer that was laying around and wanted to put it into a Dell Dimension 3000 with an Intel mobo. This Dell has two RAM slots, with two sticks of 256MB DDR 400 CL3 already in it, that I think came stock with it. What combination of these sticks would be best? What slots should I put what in??
