This mod lets Nvidia GeForce owners run a custom VBIOS without flashing the card

Nvidia enthusiasts can now run custom VBIOS on their GeForce RTX 30, 40, and 50 series cards without flashing the card's flash chip, thanks to three new tools released by a developer. The tools allow users to edit VBIOS settings, such as power limits, voltage ceilings, clock offset ranges, and fan controls, directly through the driver rather than writing to the card's flash chip.

While using the tools, the VBIOS settings are stored in the GPU's driver registry key on Windows and patched in Nvidia's open kernel modules on Linux. This allows the GPU to boot from the custom VBIOS image instead of the one on the card. The developer has tested aggressive settings on high-end cards like the RTX 5090 FE, which saw a board power ceiling increase from 600 W to 700 W and voltage ceilings increase from 1,110 mV to 1,150 mV.

Users are advised to keep a copy of the original ROM and test on a non-display GPU before applying the custom VBIOS. However, the developer warns that the hardware is not made any tougher and that pushing higher power through the card's 12V-2x6 connector is a significant risk. Nvidia is likely to patch the method in upcoming drivers, so users should enjoy the features while they can.
