Nvidia-375.10 BETA still exhibits the same issues, updated post with log file with the command you requested.
I dont know how to debug nvidia-smi any further to make it report the remaining data,
however i know that nvidia-settings CAN capture those data. I also updated the post with a file with the output of “optirun -b none nvidia-settings -c :8 -q all”.
In addition, i discovered this way that the reported powermizer modes in the gui are wrong. i can see 3 instead of 2 in the nvidia-settings logfile. (correct me if i’m wrong here)
Should i proceed with making a bash script to record all with nvidia-settings instead?
Hi oanonymos0,
We have investigated this issue found improvement in clock is expected behavior with latest driver. This is not a bug, the behavior you is seeing w.r.t. clocks values in battery mode are indeed expected (R367_00 introduced an expected behavior).
We may try to focus on “overheating” issue. Could you please share what different did you find in GPU temperature with earlier and latest driver? Please provide reproduction steps for overheating issue. Is it only happen when you play the games? How long need to play game. What is min and max temperature reading?
so this means that the behaviour is intended? I am really negatively affected by this change in behaviour. I propose two possible solutions:
Make an option to disable turbo boost globally (and in my case cap the maximum clocks to 835Mhz) in nvidia settings. I believe this is the best (and AFAIK the easiest) solution that would solve this issue completely. Many laptop users would benefit from that.
The issue with turbo boost is that the GPU keeps its 950Mhz, even when reaching high temperatures of 80-90C, which makes the CPU throttle and severely degrades performance, if not cause the laptop to shutdown. [i’ve experienced that] The solution to this would be to disable this turbo boost after some temperature threshold (like 75-80C?). The performance drop would be minimal and AFAIK this is the behaviour seen on windows too. It will benefit users with not-so-good cooling systems a lot as well.
Unfortunately i dont think you could do something to reduce overheating, other than reducing clock values.
My laptop likes to heat a lot in general and i can only reduce heating by lowering clock values both on CPU and GPU, especially in the summer. I also tried cleaning the dust and putting new thermal paste but it didnt help much. Anyways, I will provide what you requested ASAP.
I think this will help you to get around his higher clocks issue. Need to restart the X server and launch nvidia-settings application. In nvidia-settings, you can set the gpu clock offset to -ve value so that it won’t reach the max clock which causes heating issue.

I want to clarify, the nature of the risks. Does the warning refer to incorrect usage of coolbits? Does it only refer to old laptops/desktops?
Or is there still a risk that my computer will get bricked while following your instructions? If so, how likely is it?
If it is the latter, i believe adding an option to disable turbo boost in nvidia-settings and/or xorg.conf without coolbits would be the ultimate solution and would help others as well who want to keep their computer cool, without the risk of coolbits.
