Usually, to overclock the Navi 21 GPU over 2700 MHz, it is necessary to use extreme cooling methods, such as liquid nitrogen, helium, or the Peltier module, however, the German overclocker Faktorx2 was able to set a record in the 3DMark – Time Spy discipline using a relatively affordable, custom liquid cooling system.
A fullcaver waterblock was installed on the AMD Radeon RX 6900 XT graphics card, most likely of the reference design, which allowed Faktorx2 to overclock the graphics processor to 2900 MHz (+58.90% to the base), GDDR6 video memory to 2100 MHz (+5.00% to the base) and complete the 3DMark – Time Spy benchmark with a score of 22987 points:
The Intel Core i9-7980XE CPU was overclocked to a frequency of 5000 MHz (+92.31% to the base) and was also cooled by the liquid cooling system connected to the same pump as the graphics card.
The test setup (in fact, the system unit) of the overclocker consisted of the following components:
- Processor – Intel Core i9 7980XE;
- Motherboard – EVGA X299 Dark (151-SX-E299-KR);
- RAM – G.SKILL Trident Z Royal.
And it looked like this:
