Manny - Look at http://www.crucial.com/ . They have an on-line tool available which will tell you exactly what you need based on the specific model number of the Dimension. (And, Crucial makes very good memory modules).Doug

Thanks Doug.They don't seem to have memory for Dimension XPS Gen2. They have for Gen3 onwards and smaller systems as well. .but for some reason they don't have Gen2 listed.I went to similar sites...and most of them recommends the following.http://www.computer-memory-store.com/dimen...n%202&submit=GOPC3200 DDR SDRAM DIMMs. Supports Dual Channel DDR.Except one comes up withhttp://www.orcalogic.co.uk/asp/Dell_Dimens...y-21259-m-1.htmMemory Type : DDR2 PC2-4200 (533MHz) DIMM Notes : The Dell Dimension XPS Gen 2 (G2) supports Dual Channel Memory. Memory Modules must be ordered & installed in Pairs for Dual Channel mode to function. So I am really confused Manny

I'd contact Crucial directly and see what they recommend. They are a known supplier and I'd trust their advice. I think you have the same memory as the 4600. If so, the PC3200 is the right answer.Doug
