I currently have 512MB of Corsair DDR XMS3200LLPT TwinX Platinum CAS2 (2 x 256mb sticks) on my abit nforce2-s motherboard. I'd like to upgrade the memory to 1GB and have one memory slot left on the board whats the best economic upgrade option available to me? looking for best web price and of course compatability with the current sticks... (i figure three sticks of memory should still be able to run in dual 400mhz mode like the current pair do?!?) also what slots would the three sticks need to be in for best performance?
as always, advice much appreciated
