Hi everyone! I am running a Ryzen 2600 and an RTX 2060 for Rosetta and Asteroids @home. I dedicate the CPUs to Rosetta and the GPU to Asteroids. During the hottest part of the day my GPU starts to run pretty hot running full-bore non-stop. Is there a way I can throttle it down to run at like 75% power or something to control heat during the day?

I have MSI afterburner installed so if there is a way to do it with that I am open to that as well.

Thank you!

For a single GPU create this script:

#!/bin/bash
/usr/bin/nvidia-smi -pm 1
/usr/bin/nvidia-smi -acp UNRESTRICTED
/usr/bin/nvidia-smi -i 0 -pl 160
/usr/bin/nvidia-settings -a "[gpu:0]/GPUPowerMizerMode=1"
/usr/bin/nvidia-settings -a "[gpu:0]/GPUMemoryTransferRateOffset[3]=400" -a "[gpu:0]/GPUGraphicsClockOffset[3]=100"
/usr/bin/nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUTargetFanSpeed=75" -a "[fan:1]/GPUTargetFanSpeed=75"

For 2 or more GPUs expand the script like so:

#!/bin/bash
/usr/bin/nvidia-smi -pm 1
/usr/bin/nvidia-smi -acp UNRESTRICTED
/usr/bin/nvidia-smi -i 0 -pl 160
/usr/bin/nvidia-smi -i 1 -pl 160
/usr/bin/nvidia-settings -a "[gpu:0]/GPUPowerMizerMode=1"
/usr/bin/nvidia-settings -a "[gpu:1]/GPUPowerMizerMode=1"
/usr/bin/nvidia-settings -a "[gpu:0]/GPUMemoryTransferRateOffset[3]=400" -a "[gpu:0]/GPUGraphicsClockOffset[3]=100"
/usr/bin/nvidia-settings -a "[gpu:1]/GPUMemoryTransferRateOffset[3]=400" -a "[gpu:1]/GPUGraphicsClockOffset[3]=100"
/usr/bin/nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUTargetFanSpeed=75" -a "[fan:1]/GPUTargetFanSpeed=75"
/usr/bin/nvidia-settings -a "[gpu:1]/GPUFanControlState=1" -a "[fan:2]/GPUTargetFanSpeed=75" -a "[fan:3]/GPUTargetFanSpeed=75"

[3] for Pascal or [4] for Turing

Then run this command once:

sudo nvidia-xconfig --enable-all-gpus --cool-bits=28 --allow-empty-initial-configuration

Use this to check if it took:

sudo xed /etc/X11/xorg.conf

Saves me a lot on electricity and still runs BOINC projects great.

Where do I save that code so it gets run with the command? Is it easy enough to switch back to normal when I want to play a game or something?

Slide the sliders in Afterburner, if they slide together and you don't want them to click the link linking them and they will be unlinked.

Set "Power Limit" from 100% to 70%. Let the link with "Temp. Limit" enabled.
You save ~27% electricity and it runs ~8°C cooler.
You can check it with Afterburners Hardware Monitor.
