During G.Skill's 5th Annual OC World Record Stage 2016, well known overclockers like Splave, Hiwa, Dancop, Benchbros and other have managed to break quite a few world records and global first place records with various hardware and G.Skill memory, including DDR4 frequency, HWBOT Prime, as well as various 3DMark and Unigine Heaven benchmarks.
G.Skill Trident Z DDR4 memory was also a part of Kingpin's insane looking LN2 setup as well as a part of many other overclocking systems at Computex 2016 show.
The 5189.2MHz memory frequency really sounds impressive and hopefully we will see even higher records in near future.
