- Experimental Ada IDs need their own opt-in flag and an exact PCI address; targets=all never selects them in gpu-unlock-ada.
How to unlock the RTX 4080
01Clone and install the project on Linux.
git clone https://github.com/JustAResearcher/gpu-unlock-ada cd gpu-unlock-ada make install
02Add this to your kernel command line. Replace the address with yours from lspci -D.
gpu_unlock.targets=0000:01:00.0 gpu_unlock.rtx4080_experimental=1
03Power off, start again, and check the log.
journalctl -k -b | grep gpu_unlock
FAQ
Can the RTX 4080 be unlocked on Windows?
No Windows port reports the RTX 4080 yet. Use Linux. WSL2 does not help, because the unlock must run before the Windows driver starts.
Which PCI device IDs does the RTX 4080 use?
10de:2704. Check yours with lspci -nn | grep -i nvidia.
