A specialized 800-watt overclocking BIOS, originally developed for ASUS' ROG Matrix RTX 5090, is being successfully installed on competing graphics cards. Users on an online forum have reported flashing this firmware onto RTX 5090 models from manufacturers including Gigabyte, PNY, and MSI. The modification enables these cards to operate with a significantly higher power limit, resulting in clock speed increases of 100 to 200 MHz.
This BIOS flash is not universally compatible, however. The procedure appears to work only on cards with a triple fan-header configuration, matching the ROG Matrix's design. Models like the ASUS Astral Air and ASUS TUF, which feature only two fan headers, have not accepted the firmware successfully. The higher power draw also increases the electrical load on the 16-pin power connector, a component with a known history of reliability concerns.
While the process can enhance performance, flashing a graphics card with a BIOS from a different manufacturer carries inherent risks. Experts caution that it can lead to unpredictable operation and potential hardware damage.
