Radeon RX 6900 XT Overclock Faktorx2 on Water Cooling Without Nitrogen

Normally, pushing Navi 21 GPUs past 2700MHz demands extreme cooling solutions like liquid nitrogen, helium, or Peltier modules. However, German overclocker Faktorx2 managed to set a record in the 3DMark - Time Spy discipline using a relatively accessible custom liquid cooling system.

A full-cover water block was mounted on the AMD Radeon RX 6900 XT graphics card, which was likely a reference design. This setup enabled Faktorx2 to push the GPU to 2900MHz (+58.90% over stock) and the GDDR6 video memory to 2100MHz (+5.00% over stock), ultimately completing the 3DMark - Time Spy benchmark with an impressive score of 22987.

The Intel Core i9-7980XE CPU was simultaneously overclocked to 5000MHz (+92.31% over stock) and shared the same liquid cooling system, running off the same pump as the graphics card.

The overclocker's test bench, which was essentially a complete PC, comprised the following components:

Processor: Intel Core i9 7980XE;
Motherboard: EVGA X299 Dark (151-SX-E299-KR);
RAM: G.SKILL Trident Z Royal.
