Nvidia ended video BIOS modification over a decade in the past when it added BIOS signature checks. Using an on-die safety processor named Falcon, the corporate stopped customers from altering the BIOS their card ships with. The GeForce 900 collection was the primary to characteristic the safety chip, which has been saved in use as much as the present RTX 40 collection. Now all these years later, somebody has managed to interrupt Nvidia’s safety measures.
As TechPowerUP factors out, software program builders and modders not too long ago found a backdoor that allowed them to get round Nvidia’s safety resolution and launched a instrument that takes benefit of mentioned backdoor. Veii’s OMGVflash and Kefi’s NVflashk are two independently developed instruments that let you flash virtually any BIOS onto practically any Nvidia GeForce GPU, bypassing safety limitations resembling BIOS signature checks and vendor/machine checks (cross-flashing). vBIOS signature examine bypass is supported as much as RTX 20-series GPUs, permitting you to customize the BIOS, whereas cross-flashing (sub-vendor ID examine bypass) is supported even on the RTX 4090.

Veii has introduced the instrument’s first public beta and shared the event historical past, use directions, and a few technical assist by way of a put up on the TechPowerUP boards. Kefi created an analogous put up on the TechPowerUp boards too, giving us some perception on the event, logic, and work behind the instrument. Moreover, the software program developer is now engaged on a GUI model that makes backing up and flashing the BIOS easier and lets customers search TPU’s database for GPU BIOSes.
The purposes of such instruments are immense. For instance, chances are you’ll flash the BIOS of a factory-overclocked graphics card onto a reference-spec card to extend the ability limits and clock speeds. BIOS modification additionally provides you management over the graphics card’s voltages, cooling efficiency, and fan curve, permitting you to make your card quieter so long as your cooler can stop the GPU from exceeding thermal limitations (which you can too alter).
KitGuru says: Note that tampering with the vBIOS will invalidate the guarantee in your graphics card. Graphics card BIOS modification, like all modding, is dangerous and may solely be performed by skilled customers.
