https://www.overclock3d.net/news/cpu_mainboard/msi_breaks_ddr4_world_record_with_5608mhz_memory/1 Just in the beginning of 2019, MSI's in-house overclocker, Toppc, pushes the DDR4 speeds to 5.6GHz, setting another barrier using Kingston memory and the MSI Z390I GAMING EDGE AC motherboard by liquid nitrogen cooling. This world record not only shows MSI's dominant position on performance for Intel 9th generation processors by using MSI MPG Z390I GAMING EDGE AC and MSI's unique and patented DDR4 Boost technology, but also reveals team-up power with Kingston DDR4 memory. Congrats to overclocker Toppc for this achievement.
