I have installed my driver successfully. My card is:
GeForce RTX 3060 Ventus 2x 12G OC
The vendor I bought my NVDIA card from - msi.com - follows-up by promoting Windows 10 ‘utility’ software for the card under its own brand name - one feature being overclocking. This company does not have Linux utility software.
Is there any such software for Linux, and do I even need it? Am I good to go with just the driver?
There is no control software for NVIDIA GPU’s. Overclocking can be applied with “nvidia-settings” utility, most distrubitions installs itself, if you use Arch you may install seperately with “sudo pacman -S nvidia-settings”. For overclocking you have to create x-config that coolbits setting enabled. Open a terminal and write "sudo nvidia-xconfig --cool-bits=16. After reboot it enables overclocking and manual fan control. It only works X servers, there is no method for Wayland now. You can change allowed TGP with nvidia-smi utility. If you have issue with this setting, just jump to another TTY, login and remove /etc/X11/xorg.conf and reboot.
