It goes way to high in clock frequency … 1354Mhz ? instead of BASE: 1127 MHz / BOOST: 1178 MHz (1152 / 1203 MHz in OC Mode)
I only noticed now because i wanted to stop GPU from going up and down while on desktop or in game in order to reduce frame latency. As with my 7600GT it was 1-2ms frame time, with my GTX960 it’s above 10ms (up to 25ms).
It also seems PowerMizer is not working as i didn’t find a solution to Disable Adaptative Clocking, or to set my frenquency as i would like it to be.
I’ve noticed that the default clocks under Linux tend to be a bit higher than the reported stock clocks for the same GPUs under Windows, at least for Maxwell.
Frame latency is a tough nut to crack on Linux in general, due to Xorg adding a few ms of overhead, and most compositors not getting out of the way for OpenGL applications the way that they theoretically should. It is possible, though, that in your case you’re seeing TDP or temperature throttling due to the unsustainable overclock.
There is a way to allow Nvidia settings to control overclock, though – make an /etc/X11/xorg.conf containing only this:
They have a bug report page, but it’s buried on their website, and typically doesn’t get looked at by anyone with experience with the Linux driver – you’ll have better luck here, just wait for a developer to come to this thread.
1264 might still be stable, though, if the manufacturer overclock goes up to 1200 – are you sure it’s still causing a problem?
Don’t graphics card these days have a power target? Meaning that as long as there is thermal headroom they’ll try to increase the clockspeeds.
EDIT: I had to use an URL shortener for this Youtube link, because the forum tried to embed it which didn’t really work. Even when putting URL tags around it.
As i could just overclock my GPU/MEM at normal clocks speed, and my problem would be fixed for good! (i think i can’t overclock when it’s like that, need to test it again, later, lol)
60c is not hot for a modern GPU. I think blackout is correct that the card might actually be totally stable at this point unless you’re seeing obvious throttling behaviour.
One way to do this is to use Maxwell BIOS tweaker via wine and nvflash for linux.
In there you can limit all power states, frequencies and etc. There are youtube guides on how to do that on windows, virtually the only difference on linux is running maxwell tweaker via wine and using linux native nvflash in linux shell instead of windows cmd.exe.
