Aah, just a few MHz more this time. But G.SKILL has a new record for fastest DDR4 memory frequency, set at 4355 MHz. The record was set with G.SKILL's extreme performance Ripjaws 4 series DDR4 memory on the ASUS Rampage V Extreme motherboard and Intel i7-5960X processor - with liquid nitrogen.
In addition to this new DDR4 frequency record, G.SKILL memory kits have also been used to set a total of 9 world records in January 2015 (source). TridentX series memory and 3 world records set with the G.SKILL Ripjaws 4 series memory, this marks a great start to the year or 2015.
