GIGABYTE RTX 5090 works with leaked ROG Astral RTX 5090 XOC BIOS: provides 1600W power limit

GIGABYTE's custom GeForce RTX 5090 AORUS Master graphics card has had its BIOS flashed with the leaked XOC BIOS for the ASUS ROG Astral RTX 5090 D, pushing its power limit to 1600W and providing around 10% more performance over the stock BIOS.

YouTuber JayzTwoCents used the leaked XOC BIOS for the ASUS ROG Astral RTX 5090 D on his GIGABYTE RTX 5090 (non-D) AORUS Master, which on the ROG Astral RTX 5090 enables a huge 2001W power limit, but on the RTX 5090 non-D it's limited to 1600W. None of the custom RTX 5090 cards have dual 16-pin power connectors, which is why we won't see them pushed up to 2001W TDPs.

Once the XOC BIOS was flashed to the RTX 5090 AORUS Master, JayzTwoCents noticed that one of the fans on graphics card stopped spinning, which is because the RTX 50 series GPUs support up to three fan controllers, and the ROG Astral RTX 5090 has four fans but uses two controllers.

The RTX 5090 AORUS Master uses three controllers, but because the ASUS RTX 5090 only supports two, the third controller doesn't enable because it doesn't receive any EPROM flash data, disabling one of the fans in the process.

JayzTwoCents had the GIGABYTE RTX 5090 AORUS Master with the XOC BIOS and at a 900W power limit with 350MHz+ to the CPU core and 3990MHz+ on the GDDR7 memory with 10.3% more performance than stock. With the stock BIOS, the RTX 5090 AORUS Master scores 41,539 points in 3DMark Port Royal testing, while with the XOC BIOS it pushed up to 43,315 (10.3% more performance).
