Hello everybody.
From few weeks I am trying to overclock my Nvidia 3090 gpus. I was installed ubuntu, install drivers etc. Everything (mining) was work stable, but i have only 107Mh per gpus. I tried to make some overclocking but after few hours i was able to overclock only one card (main one).
My configuration:
- MB: Asrock H110 Pro BTC+
- GPUS: 5x RTX3090
- System: Ubuntu 20.04
- Nvidia Drivers: 470.63.01
One GPU is connected to PCI x16 - screen is connected to this GPU (only this GPU i could overclk), rest is connected to PCI x1. (I was also tryed to connect screen to integrated GPU or others, mining is working but ovclk also do not)
Here’s what i did:
-
- Set up coolbits to 26 (i wase used command: ‘nvidia-xconfig --cool-bits=28‘ and also change xorg.conf adding option coolbit to section ‘screen’ an ‘device’ )
- -Set nvidia-xconfig --enable-all-gpus
- -Set persistence mode (nvidia-smi -pm 1)
- -Set PowerMizer mode = 1 via nvidia-settings
- -Set the "GPUGraphicsClockOffset[3] and GPUMemoryTranserRateOffset[3] (but it was doesnt work – I had to use :
Everything is working only for GPU0, for other GPUS nothing happend.
I also run GUI i go to nvidia-x-settings to try change value on graphics mode. I can make it only for GPU0 – on other GPUs this performance level option is anavialable.
I tried to connect screen to other GPU – no changes
What is wrong? Why i cant overclock other GPUS connected to PCI x1?
My actual xorg.conf:
