The overclockers at Team OGS have secured a new HWBOT-confirmed overclocking record, pushing a Galax RTX 5090D special-edition card to over 4GHz. It’s the first time that particular GPU frequency barrier has been broken, VideoCardz reports.
The overclock was fully validated with the GPUPI benchmark, achieving a time of 35 seconds and 377 milliseconds, beating Splave’s previous effort by over a second and more than 120MHz.
The last graphics frequency record was broken in February by famed overclocker Splave using an RX 9060 XT. While that card reached over 4.7GHz and is unlikely to be beaten anytime soon, it’s a whole different beast reaching these sorts of extreme frequencies with an RTX 5090D. That card does have less memory than the standard 5090, with just 24GB, but it was a special edition with advanced VRMs. Team OGS also used a combination of liquid nitrogen and an external clock board to reach it.
The RTX 5090D HOG OC Lab Plus-X version of the card has a 36-phase VRM design, the same 21,760 CUDA cores as the standard card, and a 384-bit memory bus. But it’s built for heavy custom overclocks, which is why Team OGS could push it so far with a little liquid nitrogen.

The test system included an Intel Core i9 14900KF running at 6GHz, 32GB of DDR5 running at 4,200MT/s, and a 3,000-watt Corsair WS3000 power supply. Because when you’re running a card like this and pulling over 1,000W by itself, you need a hefty PSU to handle it.
This is the first time anyone has managed to make an RTX 50-series Blackwell GPU of any size or shape succeed in posting results and light benchmarks while running at such high frequencies. It’s not the kind of overclock you could run day to day, or even benchmark in games—it’s not stable enough for that. This is a proof of concept for a very extreme concept indeed.
But it’s impressive nonetheless, and shows there are still depths to be plumbed with existing Blackwell architecture—something we may have to continue doing for the next year if neither Nvidia nor AMD seems keen to release any new GPUs before 2027 at the earliest.
