Graphics processor Radeon RX 6900 XT overclocked to 3225 MHz – this is an absolute world record

German overclocker Roman “der8auer” Hartung has overclocked the select Navi 21 XTXH GPU in the Radeon RX 6900 XT to over 3.2 GHz. AMD recently updated the Radeon RX 6900 XT with Navi 21 XTXH chips with higher overclocking potential. So far, these GPUs have been included in the new PowerColor Ultimate graphics cards.

Previous versions of the Radeon RX 6000 series graphics cards were artificially set to limit the GPU frequency at 3 GHz. Any attempts to raise the frequency above this value did not end with anything. In the updated modification of the Navi 21 XTXH processor, the overclocking threshold has been increased to 4 GHz.

For the experiment, the enthusiast used the PowerColor Radeon RX 6900 XT Liquid Devil Ultimate model, which comes with a pre-installed liquid cooling water block. Before starting the extreme overclocking, he tested the card’s capabilities using the standard cooling system. Roman managed to overclock the GPU “underwater” to a frequency of 2820 MHz, which is 280 MHz higher than the one suggested by the manufacturer. The chip temperature, when tested in the 3DMark Time Spy test, was 86 degrees Celsius.

Then the enthusiast started overclocking the video card using liquid nitrogen. At a temperature of -87 degrees Celsius, the graphics accelerator behaved unstably, showing artifacts on the screen. However, Roman carried out more fine-tuning and, as a result, was able to achieve a GPU frequency of 3225 MHz, which was recorded by the software GPU-Z. For several days Roman tried to raise the frequency of the graphics chip even higher but could not. But in any case, he set a new world record for GPU overclocking.
