added: 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

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! Konny
