GoKawiilNew tool lets RTX 30/40/50 owners run modified VBIOS without flashing hardware
A developer released a VBIOS editor plus Windows and Linux loaders that let GeForce RTX 30, 40 and 50 series owners run custom firmware without writing to the GPU's flash chip. On Windows the edited image is stored in the driver's registry key and loaded at GPU restart, while the Linux version patches Nvidia's open kernel modules to boot the GSP firmware from the custom image. The editor exposes controls such as power limits, voltage ceilings, clock offsets, current protections and fan settings, with examples including an RTX 5090 FE raised from a 600W to 700W power ceiling and an RTX 4090 pushed to 671W from 550W.
