keeph8n sets three records in the ranks of the AMD Radeon HD 6990 graphics card

The American overclocker keeph8n won three gold medals in the ranks of the dual-processor AMD Radeon HD 6990 video card. The chips of the monstrous device were cooled by a liquid cooling system and were overclocked to an average of 985MHz, and the GDDR5 video memory was up to an effective 5800MHz.
In addition, an Intel Core i9-10900K processor overclocked to 6800 MHz with liquid nitrogen played an important role in these records. As I mentioned earlier, older versions of the 3DMark benchmark are quite sensitive to CPU performance.
