Forgive the stupid question, but just to make sure I understand what we're talking about here, this is the sort of memory I can stick into the Dell 4500 (Pentium 4, 1.8Ghz desktop machine) I bought this past summer, right?
I know that computer takes DDR PC2100 RAM; it's the "SO-DIMM 200-pin" part that I don't recognize right off the top of my head.
(No, I'm not just jumping on the deal for the sake of getting a great buy. I can honestly use an extra 512mb of RAM. Photoshop is a seductive mistress, but a most memory-hungry one.)
