  "account": "The GeForce RTX 50 series graphics cards can now have their performance limits altered through a modified VBIOS, without the need to physically flash the card's VBIOS chip. This method removes the risk of bricking the card, as the flash process is bypassed entirely. The VBIOS sets the hardware's power draw, voltage, clocks, fan speed, and other parameters, with different values assigned by board partners depending on the card's premium or budget status. Modifying the VBIOS enables users to push the limits higher for overclocking enthusiasts, or lower for quieter, cooler, and more power-efficient operation. Since Nvidia began signing their firmware and using onboard security processors, tools have emerged to bypass these protections, but only for cards newer than the RTX 20-series. The modified VBIOS is stored in the GPU's driver settings within the registry on Windows, and in the open-source kernel modules on Linux. The driver reads it in place of the chip's copy when the card starts. If the image is rejected, the card falls back to its stock VBIOS. These modifications have both risks and benefits, with the latter being primarily aimed at tinkerers and overclockers, while the former could potentially cause hardware damage.",
