matmat07 Posted September 29, 2008 Report Share Posted September 29, 2008 After more than a month of searching for a good solution to get rid of my downclocking issue, I decided to make a summary of what I remember trying to do. I hope someone will put the finger on a solution I missed, since I don't really like the alternative that are offered to me. What happen: I play unreal tournament 3 and the game freeze for a couple of sec then unfreeze in low 3d mode. Really annoying since I get killed while waiting and lose too much fps if I try to continue playing. Heres a couple of stat I gattered. Orthos is a cpu stresser and atitool an gpu stresser: Raised laptop: Max temperature acheive on gpu: 67°C (unreal tournament 3(cpu 67)) Min temperature acheive on gpu: 47°C Max temperature acheive on cpu: 76°C (orthos) Min temperature acheive on cpu: 25°C Raised laptop, undervolted cpu: Max temperature acheive on gpu: 67°C(atitool and orthos(cpu 62)) Min temperature acheive on gpu: 45°C Max temperature acheive on cpu: 65°C(atitool and orthos(gpu 67) Min temperature acheive on cpu: 20°C Also, when I used atitool and orthos without an UV cpu, my cpu throttle got down to 900MHz instead of 2.0GHz at these temp(gpu/cpu): 66/71 67/71 63/70. So when cpu reach 70 and gpu is high enought we could say. I don't think it is related with the UT3 case since no throttling was observed when the game froze. Also, 67°C was reach on both gpu and cpu without any downclocking in game. It can happen a lot of time after reaching a max. Now, what I tried: Using new and different driver (only signed because of my blu-ray player) Deleting old driver before installing new one Lowering my temp(raise laptop, undervolt: Helped a bit but UC is still too frequent Keep playing even if low 3d mode is acheive -> goes into 2d mode Putting low quality settings and tweak Underclocking myself a bit (25/50 I think, someone told it solved his issue) Maybe I forgot something, I did not write everything I tried when I tried. I had to use my memory. Using rivatuner with force constant perfomance level works, but I'm afraid of damaging the graphic card. I could try buying a laptop cooler too, but if the problem is not heating it woulb be money spent for nothing. Quote Link to comment Share on other sites More sharing options...
Bades Posted September 30, 2008 Report Share Posted September 30, 2008 I think its powermizer. It downclocks your GPU to safe power even on AC. If on XP, go into CP and you can turn it off. On Vista, google a program called powermizer switch, d/l it and turn powermizer AC off. There shouldn't b anymore downclocking. Quote Link to comment Share on other sites More sharing options...
matmat07 Posted September 30, 2008 Author Report Share Posted September 30, 2008 Tryed, but it still downclocked :) . But I think it gave me some FPS :) Quote Link to comment Share on other sites More sharing options...
matmat07 Posted October 27, 2008 Author Report Share Posted October 27, 2008 I tryed the 169.04 driver, and so far it hasn't happen. Quote Link to comment Share on other sites More sharing options...
