Recent breakthroughs pave the way for renewed vBIOS modding, offering enthusiasts a chance to cross-flash, tweak voltages, and more.
Around a decade ago, Nvidia introduced signature checks for vBIOS, effectively closing the door on the world of enthusiast vBIOS modding. Today, an intriguing development surfaces as TechPowerUp reveals that two members of its forum have independently unveiled new software tools that reignite modding possibilities. These include flashing BIOS from premium to reference cards, adjusting power limits, controlling voltages, fan-curves, and more.
Back when Nvidia unveiled the Maxwell GPU architecture, specifically the GeForce 900 series, it introduced an on-die security processor known as Falcon. This move was aimed at thwarting counterfeiters by implementing vBIOS signature checks and vendor/device verifications. However, this step also curbed the meticulous control modders had previously enjoyed over Nvidia GPUs through vBIOS modding techniques.
TechPowerUp claims to have meticulously inspected the binary code of both new tools, namely OMGVflash by Veii and NVflashk by Kefi, asserting their cleanliness from viruses or Trojans. Let's delve deeper into the characteristics of these two tools.
OMGVflash
Veii has provided comprehensive insights and usage
instructions for OMGVflash on the dedicated forum post. As of now, this tool is
compatible with Turing architecture (RTX 20, GTX 16) cards and older models,
offering comprehensive cross-flash capabilities.

The developer of this modding tool adds that OMGVflash empowers users to "flash what you desire [FE / VendorCert / XOC Cert / MasterCert etc], as long as EEPROM size can take it." Additionally, Veii has shared guidance on recovering a bricked card, should the need arise.
NVflashk
Kefi's forum thread delving into NVflashk is equally detailed, with the release and documentation accessible on GitHub. This iteration is described as a reverse-engineered and patched version of nvflash. What's intriguing is that its inspiration arose from the developer's ambition to flash their Asus GeForce RTX 4090 TUF OC edition to the 1000W XOC BIOS. Prior to this development, the 'Board ID mismatch' error prevented such re-flashing endeavors. Employing NVflashk, the RTX 4090's voltage could be elevated from 1.07v to the desired 1.1v.
Potential users are cautioned about NVflashk's potency. With great power comes substantial risk, as it will "attempt to flash anything to anything." Nevertheless, the developer believes uncertified or modified BIOSes might not be flashable under current circumstances. To infuse some humor into the software, amusing warnings, confirmations, and messages have been integrated.
Exercise Caution
It's crucial to bear in mind that delving into vBIOS modding for your graphics card will likely void warranties and carry inherent risks. If the allure of tinkering beckons, remember to create a backup of your vBIOS and ensure you have access to recovery tools (an iGPU or spare GPU) before proceeding with the utmost care.
