We’ve seen some pretty extreme overclocking over the years, but this new memory overclock is very impressive! Chinese overclocker “baby-j” has set a new world record by overclocking his Crucial Ballistix Max DDR4-4000 memory kit to an amazing 7004.2 MHz! This makes it the highest frequency ever hit on DDR4 memory!
This overclock was done using liquid nitrogen to cool the memory of course. The overclock was achieved on an AMD B550 motherboard running a Ryzen 5 PRO 4650G processor, which appears to have a really good memory controller. The memory was running at 22-26-26-46-127-1 (tCAS-tRC-tRP-tRAS-tCS-tCR) settings.
