G.SKILL is always-on the forefront of pushing their DDR memory to the limit, with their latest achievement setting a new memory record for DDR4 at a huge 4255MHz CL18-18-18.
This was done on the ASUS Rampage V Extreme motherboard, using the Intel Core i7-5960X using LN2. You can see on the screenshot above that using a single DIMM, they were able to hit the huge 4255MHz, which is truly insane. It would be great to see this using quad-channel DDR4, but RAM overclocking doesn't allow for those frequencies, with the records being set on single channel most of the time. But still, an amazing achievement for G.SKILL.
