At NVIDIA, they don’t really like overclocking , and this is particularly true of this generation’s RTX 5090. Indeed, by default, the card is locked everywhere, and if you’re not a handyman, you end up with a 600W power consumption limit. This is frustrating, since the manufacturers offer particularly well-built boards with high-quality PCBs, but because of this limit, you can’t go very far… Unless you take a look at Galax and the RTX 5090D HOF. Beyond the undeniable quality of this model’s PCB, there’s also a history of bios whose limits have jumped or almost jumped. We’re talking about a power limit of 2001W .
A 2000W BIOS for Galax’s RTX 5090D HOF!
Of course, this BIOS isn’t for everyone, especially as you’ll need to be an expert in the field to get your hands on it. XOC BIOSes are like family secrets – you can’t share them!
Just to note that this XOC BIOS was given to participants of a GALAX competition organized by the clocker MickaShuBL.
In any case, we know that it exists, as screenshots have been shared on various forums. These show cards whose power limits have completely jumped, reaching 2001W. The same applies to voltage, with GPU Voltage reaching 1.15V and beyond. It’s worth noting that this was a subject of debate in the overclocking community: what was the maximum voltage supported by the GPU?
Finally, another interesting piece of information: despite the power limit set at 2001W, it seems that hardware consumption limits are active. We’re talking about 1000W here. However, with this bios, the Galax HOF AI software supports fixed voltage regulation as well as memory regulation (FBVDDQ). By the way, XOC BIOSes are also available from ASUS and Gigabyte.
As you can see, all this is aimed at very specific users: extreme overclockers. This is their passion: tweaking hardware to push it to the limit and achieve ever-higher scores. And no, this isn’t an ego contest, but a real demonstration of skill. You mess up, you burn your gear.
