You may want to check if your BIOS has an option for "Discrete" or "continuous" usage of MTRRs. Experiment with both settings - I believe "discrete" should work better in a memory hoisting environmnet.
Unfortunately not! I read about other mainboards having this option in the bios and looked for it carefully, because other people reported they could fix the problem with the fglrx driver using this setting. Unfortunately, Asus didn't put such a setting in their latest release...
They're supposed to have done so, after a huge fuss we had over these issues last year. After you give me the motherboard models, BIOS vendor, and BIOS version I can hopefully get this resolved.
It's an Asus A8V Deluxe (not the A8V-E Deluxe). The bios is an AMI bios, revision 1013. This is the latest stable bios from the Asus webpage (was already onboard when I bought the motherboard).
There is a newer 1014 beta version, which I tried to test. But all efforts to update the bios on these mainboards fail, so I can't tell if the feature is available in the beta bios...
Thanks for caring! cu, Frank
