In our review of the NVIDIA RTX 4090 Suprim X we called the video card “extreme”. And we were right: just a few months after its launch, the top of the range from Team Verde has broke the world record for stable clock frequency of memory, even reaching 3.825 GHz.
The feat was carried on by the overclocker CENSXOC extensionwhich he explained with some photos posted on Twitter the setup which allowed him to reach the world record. In general, the RTX 4090 has already achieved high clock rates of memory, touching 3.7 GHz or even 3.8 GHz, but none of these records had ever been recorded in a 3D application, because on this type of program the card is more unstable and the overclock risks ending in a disaster.
CENSXOC, on the other hand, used a RTX 4090 liquid nitrogen cooledwith temperatures even below zero, to reach 3.825 GHz on the Unigine Superposition benchmark, which subjects the video card to a stress tests Full 3D. The Unigine test is almost never used by overclockers aiming for record frequencies, instead preferring applications with a low level of stress on the GPU, which thus guarantee the stability of the component while the VRAM frequencies rise.
Getting more specific about the build record-breaking, the latter was composed of a Colorful GeForce RTX 4090 iGame LAB along with an Intel Core i9-13900K on a Z790 Dark Kingpin motherboard. The cooling of the card reached a minimum of -34.6°C, but in the most problematic points of the benchmark its temperature rose to almost touch 192°C.
The result obtained by CENSXOC, however, bodes well in the fact that the RTX 4090 can exceed 4GHz of frequency, of course under the correct conditions and in the hands of an experienced overclocker. In fact, starting from the new world record, the community could start again with even more extreme overclocking builds and attempts.
