GoKawiilOpen-source tool nv-uefi-unlocker boosts RTX GPU tensor speed via USB on Windows
A new open-source project called nv-uefi-unlocker lets owners of Nvidia RTX 20, 30, and 40-series GPUs remove a built-in tensor-performance limiter by booting from a USB stick, with no VBIOS flashing or driver patching required. The tool runs before Nvidia's driver loads, rebuilding firmware locally from Nvidia's public driver files, and the developer reported a 65% jump in FP16 performance on a laptop RTX 4060.
