EVGA has today published the "XOC" BIOS version for its GeForce RTX 3090 FTW3 graphics cards. The XOC BIOS version is designed for "extreme overclocking" purposes, as it boosts the power limit of the card by very a few additional Watts. This allows the overclockers to use the card to its full potential so the GPU core is not limited by power. To run XOC BIOS on your GeForce RTX 3090 FTW3 GPU card, you need to have an adequate cooling solution and sufficient power supply. For power, EVGA recommends that you use at least 850w+ Gold PSU, at minimum. This is a sign that shows that XOC bios will boost the system power consumption by quite a bit. The XOC BIOS is enabling the GPU to have a power limit of 500 Watts. It is important to note that EVGA does not guarantee any performance increase or overclock while using this BIOS update.

You can download the EVGA XOC BIOS for GeForce RTX 3090 FTW3 graphics card here. To install it, unzip the file, run Update.exe, and after updating restart your PC. That is the complete update process for the BIOS update. EVGA uploads both the normal BIOS (so you can revert) and XOC BIOS there so be careful when choosing the right files. You can use TechPowerUp GPU-Z tool to verify the BIOS install.
