nVidia RT3070 ETH OC in Ubuntu20.04: nvidia-settings -a GPUGraphicsClockOffset/GPUMemoryTransferRateOffset not working

Graphics / Linux Linux
1

Sorry I am a new Linux and nVidia user for ETH mining but hopefully someone can help me.

I am using:
Ubuntu 20.04
2 GPUs RTX 3070
Asus B250 Mining Expert

I have installed all SW needed on a new Ubunt 20.04 like this:
sudo -i
apt install nvidia-driver-460
nvidia-xconfig -a --cool-bits=28
REBOOT

I checked my /etc/X11/xorg.conf file and coolbits = 28 was written in all 3 GPUs → OK.
I tested nvidia-smi Undervoltage / Powerlimit (pl) for all GPUs:
nvidia-smi -pl 120
and it works also → when mining with t-rex power limit is seen → OK.

Wenn I go into “NVIDIA X SETTINGS”-APP I also can change manualy under each GPU PowerMizer the values for
Graphics Clock Offset
Memory Transfer Rate Offset
and after pressing ENTER the value becomes active → when mining with t-rex Hash-Rate goes up → OK.

BUT:
Overclocking is not running with this cmds from Terminal even the promt answer is “Attribute … assingend”:

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.

Also when I check in “NVIDIA X SETTINGS”-APP under each GPU PowerMizer the value for GraphicsClockOffset und MemoryTransferRateOffset is still values 0 …

What do I make wrong ??

All the helps is much appreciated.
Thank you in advanced!

I tested nvidia-serttings fan for all GPUs like this:
nvidia-settings -a [gpu:0]/GPUFanControlState=1
nvidia-settings -a [fan:0]/GPUTargetFanSpeed=50
and it works also → fans are at once running faster

Questions:

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 also ?

Is my installation of nvidia-driver correct ? Because in forum I also saw that users intsall nvidia-driver in other way like this:
$> 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

While I don’t know how to do it with the regular nvidia settings app, look up GreenWithEnvy, which is a graphical front end that should make the overclocking process easier (though I don’t know how well it works with multiple cards).

edit: It’s also nice enough to tell you if it thinks you don’t have CoolBits set properly.
