I am having a problem with my board enabling dual channel. I got 2 stick of corsair 512MB xms 3200, problem is one is a bit older then the other, they have different revisions. System boots just fine at 200Mhz cl2, but when I run the benchmarks I only get 2950mb/s scores in sandra, and cpu-z show my board as single channel. I used to have 2 stick of 256mb hyperx kingston and it worked great and dual channel worked ok.
I changed the slots on the board to test it out, I had it in slot 1 and 3, tried 2 and 4, get the same results no dual channel.
Could the different revisions on the ram stick make the board not enable dual channel?
