A developer known as Panchovix has released a trio of tools allowing owners of Nvidia GeForce RTX 30, RTX 40, and RTX 50 series graphics cards to run custom VBIOS profiles without writing to the physical flash memory. The software suite includes a VBIOS editor alongside dedicated loaders for Windows and Linux. [1][2]
Instead of attempting to bypass signature checks via nvflash, the software bypasses traditional ROM flashing entirely. On Windows, the loader injects the tailored image into the display driver's registry key, requiring driver version 616.56 or newer and a quick driver restart. Linux users rely on patches to Nvidia's open kernel modules so the GSP firmware initializes with the custom image at boot. Memory timings cannot be altered because the hardware reads them directly from the ROM, and laptop RTX 40 GPUs are currently unsupported. [2]
The workaround unlocks massive headroom across modern architectures. Testing reveals that an RTX 5090 Founders Edition profile pushed power caps from 600W to 700W, with Panchovix achieving up to 800W, while voltages rose from 1110mV to 1150mV. Similar tests achieved 750W ceilings and +2000MHz core offsets on an RTX 4090, as well as lifting an RTX 5080 from 360W to 500W and pushing an RTX 5060 Ti to 300W. [2]
