Ok, the only reason I want to mod my bios is because the damn fan keeps ramping between 900rpm and 1400rpm while in windows. I am not sure if this is an ATI drive issue, or something that needs to be rectified by bios.
So I did some testing and tried various ways. I copied the ASUS top bios, but that is too damn loud in 2D. So I then tried messing with the TMIN and duty cycle min. My first attempt I set TMIN to 70 and my idle temps dropped to 76C from 80C. However the fan would go totally nuts during gaming, especially when a game is paused in 3D.
Then I read up about tslope, but this seems not be editiable? Any reason why? Anyway I tried another attempt, however this time using the latest rivatuner to try out my mods before flashing. I set the duty cycle to 2% and TMIN to 60%. This was ok, but still an insane amount of ramping while in 3D. I would rather use the on die chip, as messing with lookup table does not seem to be successful for me.
So any suggestions, is there a way to stop the fan ramping up and down in 2D or is this a CCC bug? Even with my mods; although it works somewhat, it still ramps. The only thing is it does not sound as bad as the fan speed starts off at a higher default. It still bloody ramps between 1100-1400rpm grr!
I look forward to your replies.
