Best Answer: Dont get 3GB because it will prevent your motherboard from using dual channel. Get 2gb or 4gb.

Re:by the way for a little more insight into the issue…
your a64 3200+ socket 939 has…. should have a built in dual channel memory controller; Other chips may rely on the chipset. You have to install each module on a different channel for the modules to work in dual channel. So try your 2, 1 gig, 2700 sticks in socket 1 and 3 if it's a no go… try 2 and 4.
Re:hey hey… dual channel memory has to match or exceed the external bus speed of the chip, your mobo has to support the feature and you're going to need equal memory modules. your problem is your memory chips.
you "have one stick of Corsair XMS DDR400 (512MB) and 2 sticks of Corsair XMS DDR333 (1gig)"
the ddr400 is 3200 and the ddr333 is 2700
get another stick of corsair xms ddr400 (512) 3200 and run that in dual channel 512 meg'ers
or
try the 2 sticks of corsair xms ddr333 (1 gig) pc2700 and have a machine with dual channel 1 gig'ers..
