Galax-sponsored TecLab OC group from Brazil has managed to push Nvidia’s GeForce RTX 4090 graphics processor to a record-breaking 3.45 GHz with the assistance of some modding and liquid nitrogen.
That is the best GPU clock pace ever achieved.
However there’s a catch. At such a excessive frequency the cardboard began exhibiting efficiency degradation — and the group needed to scale back the clock pace earlier than they have been in a position to run benchmarks.
In response to VideoCardz, the group of overclockers took Galax’s upcoming GeForce RTX 4090 SG (Severe Gaming) graphics card — a probable contender for one of many greatest graphics playing cards — which makes use of a custom-printed circuit board that’s designed to make graphics processors run at frequencies larger than these really useful by Nvidia.
Utilizing the cardboard’s quad-fan inventory cooler, the Galax GeForce RTX 4090 SG might be overclocked to three.075 GHz. However with larger voltages and excessive LN2 cooling, the GPU can hit speeds as excessive as 3.45 GHz, with reminiscence information switch charges hitting speeds of as much as 24 GT/s (in all probability the default pace of Micron’s newest 16GB GDDR6X chips).
To prep the cardboard for his or her overclocking session, the TecLab OC group needed to take away the facility restrict controller, resolder a number of the components from the entrance aspect of the PCB to the bottom of the PCB to put in the liquid nitrogen pot, and add voltage probes to raised perceive the board’s conduct.
The TecLab OC group managed to get the Galax GeForce RTX 4090 SG to three.45 GHz, which is the best GPU clock pace ever achieved. Nonetheless, at such a excessive frequency, and with liquid nitrogen, the GPU began to indicate degraded efficiency, and the group needed to scale back the clock pace to three.27 – 3.36 GHz to run benchmarks on the cardboard.
Even overclocked to ~3.3 GHz, the GeForce RTX 4090 nonetheless managed to interrupt 5 benchmark information, attaining the world’s highest efficiency scores in 3DMark Hearth Strike Extremely, 3DMark Port Royal, 3DMark Time Spy Excessive Graphics, Superposition 1080p Excessive, and Unigine Superposition 8.
When Nvidia launched its AD102 graphics processor in addition to its GeForce RTX 4090 Founders Version graphics card, it stated the GPU was designed to hit excessive clock speeds and claimed to have already run the AD102 GPU at 3.0 GHz in its labs. And now the TecLab OC group has confirmed the GPU can hit even larger clock speeds outdoors of Nvidia’s labs — as soon as it is fed with sufficient energy and cooled with liquid nitrogen, in fact.
