An intrepid overclocker has nudged a stock RTX 4090 ever closer to the magical 4GHz mark thanks to liquid nitrogen cooling and an assist by Asus. Overclocker Allen ‘Splave’ Golibersuch recently sat down with the unreleased Asus ROG Matrix RTX 4090, which is made for serious overclocking. Once the smoke cleared, he set a world record clock speed by hitting 3.945GHz. This is the highest clock speed ever for a non-3D application and painfully close to 4GHz, which has yet to be breached. The effort allows Nvidia to add another notch to the RTX 4090’s belt, as it’s not only the world’s fastest GPU but also the most overclockable, it seems.
The notorious ‘Splave’ posted the achievement on Facebook, and it was no easy feat. In addition to the ultra-premium GPU that isn’t even available yet, Golibersuch employed additional heating elements to keep temps in check. First, three Elmor Labs heaters were used to keep condensation from forming on the circuit board of the GPU. Additionally, three more heaters were used in the front, back, and near the slot to keep the PCB warm. On top of all that, a Kingpin TEK-9 Icon Extreme V5 LN2 tower was employed as well.
Even at almost 4GHz, the GPU was running at a frosty -34C.

This potent combo of hardware allowed for a GPUPi score of calculating Pi to 32 billion numbers in 46.077 seconds, according to Tom’s Hardware. Splave said this is a new world record. However, this benchmark is only for compute and not a 3D application, hence the super-high clock speed. It remains unknown what kind of clocks could be achieved in an actual gaming benchmark.
For a look at what can be achieved in actual gaming, we don’t have to look too far. Last month, an overclocker took an RTX 4090 to 3.825GHz in gaming using liquid nitrogen. The biggest difference between the two attempts is the gaming achievement was made on a limited edition Colorful RTX 4090 iGame LAB GPU, of which there are only 300 in existence. Though the ROG Matrix is undoubtedly an exclusive GPU, it’s not in the same ballpark as the Colorful version regarding overclocking controls.
There’s actually a GPU under there. As you can see, this line of work is not for the faint of heart.

The new record by Splave outpaces the previous record of 3.825GHz, which was recorded by an overclocker named OGS, who also used GPUPi for their run. It seems nobody has been able to hit 4GHz yet, which can’t be too far off. Perhaps the world’s overclockers will have to wait for the inevitable refresh of Nvidia’s GPUs to make that happen.
