NVIDIA's BIOS signature lock has been bypassed! Two new tools have emerged, enabling unprecedented vBIOS modding and crossflashing for GeForce GPUs.
Historically, NVIDIA introduced signature checks to curtail BIOS modding. Their on-die security processor, "Falcon," ensured GPUs wouldn't boot with unauthorized firmware. Until now.
OMGVflash by Veii and NVflashk by Kefinator: ground-breaking tools that bypass NVIDIA's checks, opening doors to GPU modding once believed closed.
Beyond overclocking, these tools offer performance boosts to more budget-friendly GPUs. Often, the key difference between a standard model and its overclocked counterpart is just the vBIOS.
Cross-flashing gets even more interesting: Imagine transferring the vBIOS from one vendor's GPU to another's. But always proceed with caution. Not all pairings are a match made in silicon heaven.
A deeper dive into capabilities: OMGVflash supports RTX 20-series GPUs (and older) for cross-flashing. For RTX 30 & 40 series, the same power headers are a must.

NVflashk, on the other hand, is more audacious. It will try to flash ANY BIOS—even if it's from an RTX 3060 to an RTX 4090. Success isn't guaranteed, but the boldness is commendable!

A word of caution ⚠️: Modding vBIOS will void your GPU's warranty. While most failed flashes are recoverable, it's crucial to back up the original BIOS.
Both tools hail from dedicated members of the @TechPowerUp forums. Rest assured, binary codes have been scrutinized and confirmed virus-free by the outlet.
Fun fact: NVflashk was birthed from an attempt to successfully flash a 1,000-watt vBIOS onto an RTX 4090. The outcome? A resounding success.
To most enthusiasts: Extreme modding tools aren't for everyone. New to overclocking? Start with tested GPU overclocking software first. Dive deep but stay safe!
would i use this tool now ? HELL NO ! not until i see more adoption and reviews.
