Hi, I have a Dell Studio 1450 which I have been using for the last 3years. I do play resource heavy games on it. Its a P8700@2.53Ghz, 512 dedicated ATI 4530 with 2x2GB RAM. Most recent games were giving less FPS on my system, so I decided to upgrade my RAM. After checking with my motherboard (Intel GM45) compatibilities, I upgraded to 2x4GB DDR3 1066Mhz RAM. After this upgrade my DxDiag shows only 227MB of video memory were it was 512_dedicated n 2GB_shared before. And also the same games doesn't have a noticeable video performance increase. Please help me resolve this issue. After searching a lot, i still dont know what the issue is.. Im running a windows 7 ultimate_x64 system.. Thankz..
