Hello, I have been having some memory issues and I am going to run some memory checks tonight to find out where the culprit lies. I am running 2x 500mb and 2x 1gb sticks. I believe the culprits are one of the 1gb sticks. My question is, if I find that only one of the sticks is in error, will I be able to simply remove one of the sticks and still run the other two as dual channel? I have a friend that says he's not sure if you can run a single stick of dual channel memory without it's mate (if sold in a kit). I don't know if that's true or not... so I'm coming to you guys (and gals) for help.
