The GPU vBIOS designed for extreme overclocking is generally intended for professional overclockers, but sometimes these versions become accessible to the public. Recently, a 2,001-watt XOC BIOS for ASUS GeForce RTX 5090 GPUs has emerged, enabling unprecedented power limits. This development offers multi-kilowatt-class overclocking opportunities to enthusiasts eager to experiment with their ASUS GeForce RTX 5090 cards. The XOC BIOS sets the core voltage to 1.15 V by default, regardless of the software voltage slider's position, even if the slider is at zero.

Previously, we only saw the 2,001-watt XOC BIOS for the China-exclusive ASUS ROG Astral RTX 5090D and Galax GeForce RTX 5090D HOF. This XOC BIOS allowed Galax to achieve a GPU core speed of 3,570 MHz and a GDDR7 memory speed of 2,250 MHz, boosting the effective memory speed to 36 Gbps with a bandwidth of 2.304 TB/s, nearly 29% above the standard specification. Such extreme overclocking requires multiple fused 12 V-2×6 cables or custom power delivery to bypass the connector's 600-watt limit. Additionally, custom water or LN2 cooling is necessary to prevent overheating. Installing this BIOS automatically voids the warranty, so enthusiasts should exercise caution when experimenting. This time, the XOC BIOS is compatible with the regular RTX 5090, but caution is advised when dealing with third-party BIOS, so we don't recommend it.
