Setting applications clocks is not supported

Graphics / Linux Linux

Hi everybody,

I just got 2 EVGA GTX 1070 FTW cards. Everything works fine except that I am not able to overclock the cards. When I try to use the ‘‘nvidia-smi ac’’ I get the following message:

‘Setting applications clocks is not supported for GPU 0000:01:00.0.’

I have driver version 375.66 installed as well as CUDA 8.0. I have Ubuntu 16.04.

Anyone has any ideas? I have searched for many days to find a solution but coudn’t find something that works for me.

Thanks a lot in advance.

Are u using ssh or direct access? (must use 2nd)

You can not overclock without powermizer in xorg. You need to use coolbits.

nvidia-smi

was ment to use lower clocks that stock but you can query for supported clocks:

nvidia-smi -q

if u want to overclock you need to use presistent mode (demon) coolbits and nvidia-xconfig

nvidia-persistenced --persistence-mode  #first run deamon
nvidia-smi -pm ENABLED  #2nd enable persistenced mode
nvidia-smi -pl 130  #limit TDP if u want

to run coolbits all GPU must be seen in nvidia-setting by xorg, if not :

nvidia-xconfig -a, --enable-all-gpus  #this add every screen for every gpu to xconfig.conf

now we can run collbits

nvidia-xconfig -cool-bits=28 #now u can control core & mem clocks and termal setting in xorg.

use this from console or make script if u want to auto overclock (can use crontab):

nvidia-settings -a "GPUMemoryTransferRateOffset[3]=value"
nvidia-settings -a "GPUGraphicsClockOffset[3]=value"
