Re: FX2800M - driver 260.19.44 - adaptive clocking not working
The closest system we were able to find was the M6500 with Quadro 3800M. The system design is the same, but it has a faster GPU. Clocks were working correctly on this system.
These sorts of issues are usually due to ACPI bugs in the SBIOS, kernel, or GPU driver. Could you try updating your SBIOS to the latest available version?
