Newbie Question (1gb -> 2gb compatibility)

[Helium_Junkie]

I have 2x 512 Corsair cas2.5 in my motherboard, which has 3 slots (using 1+3). I would like to go up to 2GB, is it alright to put a 1GB stick in the 3rd slot (slot 2) with what is already there? Would it need to be the exact same memory?

I hear that dual channel isnt a real issue on AMDs anyway, that still true?
More info: Its a XMS3200LLPT (TwinX) and BIOS reports the CAS as 2, not 2.5. So I guess I remembered that wrongly

I think its an Abit NF7... and a barton 2500.
