Background here, question below: I have built a few systems myself before but they all had video cards. Last week I was setting up a system that had onboard shared memory and could not install Windows without errors (98 SE or XP). The system had two DDR DIMMS, each 256 MB, that were identical and I was sharing 32MB for the video, and they were both in their respective slots. I kept getting SUWIN and General Page Fault errors in 98 SE setup and kept getting driver copying issues with XP. In my troubleshooting the problem, it came down to either the RAM or the power supply, but I was thinking the RAM more than the power supply. Anyway, after I took one DIMM out and tried setup again, both versions of Windows installed now without any issues. No issues after installation and normal operations either. Here is my question: Did this work because the one DIMM I took out was bad OR in a shared memory situation can you utilize only one DIMM when you want to share memory for the video?
