I am using Ubuntu 20.04 with 2 RTX 3070 GPUs, which I want to use for ETH mining, on an ASUS B250 Mining Expert motherboard. I have installed all needed software on a new Ubuntu 20.04 installation like this:
sudo -i apt install nvidia-driver-460 nvidia-xconfig -a --cool-bits=28 reboot I checked my
/etc/X11/xorg.conffile andcoolbits = 28was written in all 3 GPUs, which is OK.I tested
nvidia-smiUndervoltage/Powerlimit (pl) for all GPUs, using:nvidia-smi -pl 120and it also works, since mining with T-Rex the power limit is seen, which is OK.
I tested
nvidia-serttingsfan for all GPUs like this:nvidia-settings -a [gpu:0]/GPUFanControlState=1 nvidia-settings -a [fan:0]/GPUTargetFanSpeed=50and it also works. The fans start at once running faster.
When I open the NVIDIA X Server Settings app, I can manually change under each GPU's PowerMizer option the values for Graphics Clock Offset and Memory Transfer Rate Offset. After pressing Enter the value becomes active. When mining with T-Rex, the Hash-Rate goes up, which is OK.
So everything works fine, but I want to do all the above in an automated way using a shell script, which I have tried.
BUT: Overclocking is not running with these commands from the terminal. Even the prompt answer is Attribute ... assigned ... as you can see below:
$ nvidia-settings -a GPUGraphicsClockOffset[3]=-500 Attribute 'GPUGraphicsClockOffset' (katzminer-desktop:0.0) assigned to value -500. Attribute 'GPUGraphicsClockOffset' (katzminer-desktop:0.1) assigned to value -500. Attribute 'GPUGraphicsClockOffset' (katzminer-desktop:0[gpu:0]) assigned to value -500. Attribute 'GPUGraphicsClockOffset' (katzminer-desktop:0[gpu:1]) assigned to value -500. $ nvidia-settings -a GPUMemoryTransferRateOffset[3]=2200 Attribute 'GPUMemoryTransferRateOffset' (katzminer-desktop:0.0) assigned to value 2200. Attribute 'GPUMemoryTransferRateOffset' (katzminer-desktop:0.1) assigned to value 2200. Attribute 'GPUMemoryTransferRateOffset' (katzminer-desktop:0[gpu:0]) assigned to value 2200. Attribute 'GPUMemoryTransferRateOffset' (katzminer-desktop:0[gpu:1]) assigned to value 2200. When I check the NVIDIA X Server Settings app, under each GPU's PowerMizer option, the value for GPUGraphicsClockOffset and GPUMemoryTransferRateOffset is still 0.
What am I doing wrong?
I also tried for each GPU without success:
nvidia-setttings -c :0 -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=2200' nvidia-settings -c :0 -a '[gpu:0]/GPUGraphicsClockOffset[3]=-500' Do I need to use sudo before nvidia-settings?
Or do I need to set persistency mode before like this:
nvidia-smi --persistence-mode=1 Do I have to set PowerMizer-Mode too?
Is my installation of the NVIDIA drivers correct ? Because in a forum I also saw that users install the NVIDIA drivers this way:
sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt update sudo apt install ubuntu-drivers-common sudo apt install nvidia-driver-460 sudo reboot All help is much appreciated.

After a lot of struggle I found a way to make this work and created a repo.
You can find the complete working script below and also in GitHub:
#!/bin/sh # README # Before proceeding make sure that you set your coolbits to 31 # Open a terminal and do # $ sudo nvidia-xconfig -a --cool-bits=31 --allow-empty-initial-configuration # To be able to set the power limit you need to enable sudo commands without password # Do # $ sudo visudo # And then at the end of the file add the following while changing username to your user # Note the tabs after username as otherwise it won't work # username ALL = (ALL) NOPASSWD: /usr/bin/nvidia-persistenced # username ALL = (ALL) NOPASSWD: /usr/bin/nvidia-smi # Reboot the system now and continue setting the OC limits # =========================== Define OC limts =========================================== # Fans speed is in % POWER_LIMIT=150 FANS_SPEED=65 GPU_OFFSET=200 # Memory offset has to be the actual desired amount.

Use GPUGraphicsClockOffsetAllPerformanceLevels and GPUMemoryTransferRateOffsetAllPerformanceLevels instead to make it work.
In theory the [3] in GPUGraphicsClockOffset[3] is the performance level and if you do GPUGraphicsClockOffset[n] for each n as performance level then you should be able to also make it work but I haven't tried that yet.
