They also have practical value.
The world of GeForce video cards has partially returned to 10 years ago. Two independent tools appeared at once that allow you to flash the BIOS from any video card to any other video card. Almost any.
.
The tools are called OMGVflash and NVflashk. They allow you to bypass Nvidia barriers such as BIOS and manufacturer/device signature checks. Several generations ago, Nvidia introduced these solutions, and in doing so, effectively made free BIOS flashing impossible.
You can now flash BIOS from GeForce RTX 4090 to RTX 4060.
From a practical point of view, such tools allow, for example, flashing the cheapest video card of some BIOS model from the same model, but in a top modification with increased frequencies and voltages. A good example is the ability to flash the BIOS at 1.1V for the RTX 4090. This BIOS configuration was originally reserved for early production RTX 4090s. However, with the advent of the AD102-301 GPU, the maximum voltage was set to 1070mV. Without this tool, flashing such BIOS versions would not be possible
You can even flash the BIOS from an RTX 4090 to an RTX 4060, but it’s hardly worth it.
