Dual DDR question

Ok here is my problem . I am currently runnning dual ddr with Corsair XMS 3200 on my Abit NF7-s v2.0 bios 1.6 but I am getting almost the same Sandra score as I was when I was only running with one stick off ram in single mode. I know it's running in dual ddr because when I boot it says " Dual channel ddr enabled" . What is causing me to have low scores in Sandra with Dual DDR? My FSb is at 210 x 11.5. My score with Dual ddr was 3206 and my score with only one stick of ram was 3125. My memory timings are at 6 3 3 2. I have tried to put the sticks in slot 2 and 3 and also 1 and 3.

thats about right. dual ddr is more of a gimmick with the amd boards. the amd cant utilize the bandwidth like the p4's can. your runnin about average. most see around a 100-200 point boost.
