I have a MSI K8NGM2-FID board (Athlon 64/3000). I put in two Corsair 1GB PC3200/400 MHz DDR 184-pin two-sided memory sticks in the first two slots, one green/one purple, i.e., making dual channel. So far so good. Since I had a similar Kingston two-sided KVR400/512 laying around, I decided to get another that was on sale. However, I discovered after opening the package that this new stick with the same number (and voltage) is one-sided. The two work, 2944mb now showing, but I wonder if this is still dual channel operation. How can one tell if the memory configuration is working as dual channel? Thanks.
