A determined modder has successfully flashed the high-wattage vBIOS from the ASUS ROG Matrix RTX 5090 onto an ASUS ROG Astral RTX 5090, increasing power limits by +200 W. This modification, detailed on the HardwareLuxx forum, allows the Astral 5090 to draw up to 800 W, compared to its stock 600 W limit. The process, however, requires physical modifications to the GPU's PCB, specifically swapping a resistor in the EEPROM signal line. This feat is particularly significant for the black version of the Astral 5090, which has a unique fan wiring configuration.

NVIDIA's recent tightening of overclocking options via software tools has driven modders to seek alternative methods to unlock more power from GPUs. The ASUS ROG Matrix Platinum, known for its high-wattage capabilities, has become a go-to source for such vBIOS modifications. This latest mod demonstrates the community's ingenuity in pushing the boundaries of GPU performance, but it also underscores the need for advanced soldering skills and adequate cooling solutions to handle the increased power and heat.

For enthusiasts considering this mod, it's crucial to note that the black Astral 5090's unique fan wiring necessitated the PCB modification. The white version, with its separate fan header, may not require such extensive changes. This development showcases the potential for RTX 5090 users to achieve greater performance, but it also highlights the challenges and risks involved in such modifications. As NVIDIA continues to limit software overclocking, the modding community will likely explore more hardware-level solutions.
