Just to make sure: Did you reset the CMOS with the reset jumper on the mainboard?
No, I hadn't thought to try that. The BIOS indicated the CMOS checksum was bad, which I took to mean that the new version automatically threw out the old version's dataset. I then did a 'load optimal defaults', which oddly enough did not enable bank or node interleaving, and searched through menu by menu for new options. But I'll try the CMOS jumper just to be sure before I throw in the towel on this. I'm back at 3776MB (since the IOMMU is at a useless address, I disabled it), so at least I'm a little better off than when I started. I also had another funny idea I might try sometime today: disabling hardware acceleration on the ATI. These slow page flips might be the result of copying inbetween different parts of video memory. So if the frame buffer became write-only, I'm wondering if it would speed up any. That would at least make the symptom go away. Kind weird to think that turning off acceleration would speed up performance. -- David W. Hankins "If you don't do it right the first time, Software Engineer you'll just have to do it again."
