Can I?

[meee]

I currently have CORSAIR XMS2 DOMINATOR 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400C4D installed in my PC. If I add more ram of a different kind to my PC well it work with these?

If they are pretty much the same id say so, but i think corsair will advised you to buy in sets, or as close to identical as possible

[adamj97]

They probably will, but they would work better together if you got the same ram sets

Mixing 2 different kits is not recommended but many people do it succesfully. The only way to know is to install and test.

It depends on what you mean by "different kind". What they call the "form factor" has to be the same ("DDR2") - this is what make it fit in the slot. If they are of different bandwith, then the system may default to the slower speed, but some systems are a bit quirky. The same applies to latency (sometimes quoted as a CAS number). Be wary of what slots you put memory into, and if there is a maximum ceiling for your motherboard(consult the manual). One way of getting good solid advice is to visit the crucial website (Google for "Crucial Computer Memory").
