I just recently built my pc with 6GB of ram using three 2GB cards and for whatever reason 2 gigabytes of ram is being set aside for VRAM. I learned this because i checked my System in the control panel and my ram is marked as 6.00GB(3.96 usable). When i check the video ram amount in DxDiag i get 3803Mb of ram. I tried using msconfig to set the max ram to 6144 but after restarting the pc it immediately switches back to 2GB. If i uncheck the box it goes to 0 but i still get this problem.
