Nvidia vBIOS modding has been made possible again, thanks to two TechPowerUp forum members who have developed new software tools that allow for vBIOS cross-flashing, voltage modding, and more. The ability to modify the vBIOS of your graphics card is always a hot discussion point, especially among gamers, and this latest development is sure to invigorate the scene.
Nvidia introduced vBIOS signature checks with the Maxwell GPU architecture in order to enhance security and prevent modding, but now, with the help of a few developers, that safeguard appears to be circumventable.
The two tools, OMGVflash by Veii and NVflashk by Kefi, have been inspected and verified by TechPowerUp to be free of viruses or Trojans.
OMGVflash works on Turing architecture cards, and older, and allows for full crossflash capability. That means you can flash a GTX 2080 Ti BIOS to an older GTX 1080 Ti, for example, and use the latter’s full potential.
Veii also provides instructions for repairing a bricked card, if you do happen to flash something incorrectly.
NVflashk, on the other hand, is a reversed-engineered and patched version of nvflash, which allows you to flash incompatible BIOSes. It was inspired by the desire to flash an Asus GeForce RTX 4090 TUF OC edition to the 1000W XOC BIOS.
So, what does it actually do? Well, if you manage to flash the 1000W XOC BIOS to the RTX 4090, you’ll be able to increase the voltage from 1.07v to 1.1v, which should improve the card’s stability and hashrate. Of course, you’ll need to be cautious about the power of NVflashk, and the risks involved in flashing incompatible or modified BIOSes.
Again, we remind you that modding the vBIOS of your graphics card will void your warranty, and that it carries inherent risks. It’s always best to back up your vBIOS before attempting any modifications, and to have a way to run recovery tools, just in case.
