Panchovix releases tools to run modified VBIOS on RTX 30, 40, and 50-series

A developer named Panchovix has released three tools that allow owners of NVIDIA GeForce RTX 30, 40, and 50-series GPUs to run a modified VBIOS without writing to the card's flash chip. Operating across Windows and Linux, the VBIOS editor modifies power boundaries, voltage maximums, overcurrent thresholds, fan headers, and frequency offset ranges. Because edited images keep the original NVIDIA signature, they cannot be flashed using nvflash.

On Windows, the loader uses the GPU driver registry key to pick up the edited image as an override, which requires driver 616.56 or newer. Instead, the Linux utility alters open kernel drivers so the GSP firmware boots the customized file. Panchovix has tested the Linux loader on Fedora 43.

In developer testing, an RTX 5090 saw its power ceiling move from 600 W to 700 W, while an RTX 4090 saw its power ceiling move from 666 W to 750 W and its core offset range double to +2,000 MHz. Testing also showed an RTX 5090 reaching 800 W, an RTX 5080 going from 360 W to 500 W, and an RTX 5060 Ti going from 185 W to 300 W.

Laptop RTX 40 GPUs cannot be edited yet, and memory timings cannot be changed because the card reads them directly from the flash chip. Both loaders are open source, while the editor is supplied as compiled files. Pushing power and voltage thresholds higher involves significant danger.
