r/linux_gaming on Reddit: CoreCtrl

December 14, 2024 -

I recently made the switch to as-rock 7900 XT Phantom Gaming and decided to give undervolting a try using CoreCtrl. After reading through the documentation on GitLab and watching a few tutorial videos, it seemed pretty straightforward.

I set the voltage offset to -95mV, adjusted my min/max GPU clocks, and left the memory settings untouched. I also cranked the power limit to the max.

Before the undervolt, I was getting around 70 FPS @ 1440p Ultra in Cyberpunk, with power draw peaking up to 330 watts and temperatures hovering around 68-70°C. After the undervolt, I’m still hitting the same FPS, but the card now draws between 150-200 watts, with temps staying around 55-60°C.

Is it really this easy? Would love to hear if anyone has additional tips or tricks for further optimizing my setup!

This is a problem if you are using a complicated fan control setup configured by the standard fancontrol service since it will simply crash when other software changes the fan settings. You are currently out of luck if you want to use CoreCtrl to configure just your GPUs performance profiles or you want to configure nothing and just view the information it presents.

r/linux4noobs on Reddit: Too noob to install CoreCtrl

April 7, 2024 -

Hi!

I know almost nothing about linux, what I know is thanks to SteamOS.

I've been researching how to undervolt my GPU on bazzite. I "only" need to install CoreCtrl and give it full control of AMD gpu but man I'm so overwhelmed. There's a lot of commands and even though the Gitlab site has an installation guide well. it is just guidance and they assme I have knowledge that I don't and it is not noob friendly, I have to edit something called GRUB bootloader which I don't even know how to find and there's no video guides to follow.

Maybe linux isn't just for me, I have this sensation I need to know a lot of programming just to do basic things as install software, Should I go back to Windows?. I'm happy with my SteamOS machine but I just wanted to undervolt my GPU (I also don't know how to do that and I will need to follow a guide or instructions) to keep temps a little bit lower and make sure they're always safe.

Thank you for reading.
