Hey there, fairly noobish question here - i currently have 2 sticks of Corsair low latency 512MB PC3200 DDR400 Ram in my PC. Im looking at purchasing 2 sticks of Corsair 1GB PC3200 DDR400 Ram, making 3GB in total. 1) With the whole dual channel thing, will the 2x1GB sticks work in Dual channel? 2) With those added sticks being different size, will the original 512 sticks continue to run in dual channel? 3) Am i better taking out the 512 sticks and having 1GB less, but the same size sticks or does it not matter? I know the PC3200 and DDR400 stats are the same, and both sets of sticks are Corsair, but is mixing 2x512 and 2x1GB on same MOBO ok? Long winded but didnt know better way of putting it lol.
