A professional overclocker has set a new record using an Nvidia GeForce RTX 4090 card to break past the 4GHz frequency.

Allen “Splave” Golibersuch posted about the achievement on Thursday, and it was confirmed on the overclocking site HWbot. "1st GPU over 4000mhz ever!" he wrote.

The RTX 4090 initially launched with a boost clock speed at 2.5GHz. However, Golibersuch overclocked his own card to 4005MHz and then 4020MHz on benchmarks involving GPUPI, a stress-testing software that calculates the Pi mathematical constant on the graphics hardware.

A day ago, another overclocker named “Cens” used a Colorful Nvidia RTX 4090 iGame LAB card to hit 3975MHz, which was then the newest world record. But hours later, Golibersuch announced on social media that he surpassed the 4GHz threshold using an unreleased Asus RTX 4090 card.

Specifically, he used the Asus ROG Matrix RTX 4090, which is housed with its own liquid-cooling case, allowing it to hit higher clock speeds. But to hit the 4GHz clock speeds, Golibersuch decided to take things further by using liquid nitrogen—at negative 192 degrees Celsius—to cool the GPU. The liquid nitrogen was placed in a cooling pot from the vendor Kingpin, which can be mounted to the graphics card.

Golibersuch tells PCMag that topping 4GHz was “easy,” citing the build quality on Asus' RTX 4090 graphics card. “I had a Galax card before this, and you can tell the resources and engineering at a company like Asus, they are just in another playing field all together,” he says.

Golibersuch says reaching the 4GHz threshold was inevitable, but he noted: "5Ghz, idk [I don't know] if we will ever see that."

For the CPU, Golibersuch used an Intel Core i9 13900K chip, which also recently broke an overclocking record, hitting 9GHz.
