The log now shows that ForceLowPowerMode was used to set the clock at 100000 Mhz. The heat is reduced, but not by as much as I had hoped. Originally I had tried to set "LowPowerModeEngineClock" "50000", but when X started, the screen was wildly distorted and "stretched?" so that the kdm login was at the far right side of the screen.
To my experience any clock setting below 200MHz will possibly crash the machine (whole machine freeze, i.e. the PCI bus locked up). I don't know the exact lower frequency, but 200MHz seems to be a save lower limit.
Funny, I don't notice any performance difference between the clock at 400000 or 100000. Let me know what else I can send you. Thanks again!
We're not really utilizing the chip at all ATM. You might find
differences in speed when using 3D applications.
