G. Skill has set a new world record for DDR4 memory frequency overclock speed. Using a single 4GB stick of Ripjaws 4 Series DDR4 memory in single-channel mode, the company has hit a DDR4 memory frequency of 4,255MHz CL 18-18-18.
The feat was achieved on an Asus Rampage V Extreme motherboard (X99 chipset) with an Intel i7-5960X processor using a liquid nitrogen cooling system. The X99 chipset supports quad-channel memory, but a single-stick configuration is better suited for frequency record-setting.
