Performance memory and SSD specialists G.SKILL wrote to HEXUS today to excitedly inform us that it has scalped a new world record. The Taiwanese firm has managed to push its Ripjaws 4 Series DDR4 memory to 4255MHz CL18-18-18.
The Ripjaws 4 Series memory chips are designed for users to get the most out of their new Intel X99 motherboard and processor combinations. These modules are provided in kits ranging up to 64GB in capacity and speed ratings of up to 3200MHz. To make the most of the potential bandwidth on offer the kits are sold in quad-channel packs, so a 16GB kit would be comprised of 4 x 4GB modules, for example.
In extreme overclocking like this the perpetrator isn't after overall system performance, so just concentrates on pushing a single memory module to its limits. You can see, in the screenshot embedded below, that in this single channel configuration 'Shamo' managed to squeeze 4255MHz from his/her 4GB Ripjaws 4 DDR4 memory module.
To achieve this record DDR4 memory overclock a liquid nitrogen cooling system was employed. The other key system components were as follows; an Asus Rampage V Extreme motherboard (based on the X99 chipset), and an Intel i7-5960X processor. You can see from the system specs info that G.SKILL ran the 8-core, 16-thread 22nm Haswell-E i7 chip at a rather low clock frequency of 1596MHz.
G.SKILL has accomplished quite a speed increase since it first broke DDR4 memory speed records back in August. At that time, with the same model of ASUS motherboard, an Intel Core i7-5930K CPU and the same Ripjaws 4 DDR4 product it 'only' achieved 4004MHz.
