hi, i have a dell optiplex gx520 minitower Desktop. when i bought it, it had windows xp installed on it and the integrated video card memory was set to 256. Recently i installed windows vista on it but when i checked the video card memory it was set to 64. how can i increase it to be 256, because obviously it can be increased to 256. I went to bios but nothing there helped me.|||Since when is video memeory measured in Mhz. Video memory is measured in megabites. If you can get to the setup screen before the computer boots into windows, do so. There you can adjust the memory used by the video card.
As for the reason your video card went from 256meg down to 64 meg is because Vista uses more of your physical memory than XP did. Thus Vista switched it down to 64meg in order to run. It means you have to leave it at 64meg or Vista wont run. Solution is to add more RAM to your computer.|||Generally this is a setting in your BIOS (I understand you say you've been unable to locate it there).
If that is the case, you may want to see if there is an updated WIndows Vista driver for your chipset and/or display adapter.
Worst case scenario, you can pickup amazing video cards these days for as low as $40.|||Try to access the BIOS and reset your shared memory from 64 MHz to 256MHz. I don't think you can not increase the video memory. Just review it. Maybe you have just overlooked where the video memory configuration is located.|||dell usually lock you out of thier bios's, so you cant screw things up, perhaps this is the case.
