Taiwanese enthusiast Toppc, who works as a Micro-Star International "cut" overclocker, has recently set a new world record for overclocking DDR4 RAM. It was able to reach the 2804.4 MHz level, which corresponds to the effective frequency of 5608.8 MHz.
For their experiments, the Taiwanese used an MSI MPG Z390I Gaming Edge AC motherboard, an Intel Core i9-9900K engineering prototype and a single RGB HyperX Predator DDR4 bar. The memory timings during overclocking were from CL31-31-31-63, while the CPU remained active only two cores, whose frequency had to be reduced to 816 MHz (a combination of base frequency 102 MHz and multiplier x8). To cool the processor and the RAM module, glasses with liquid nitrogen were used.
By the way, the previous RAM overclocking record at 2,791.6 MHz (5,583.2 MHz effective) was set just a week ago, while the MSI MPG Z390I Gaming Edge AC mainboard also acted as the basis of the test bench.
