Just a day into the official 7th Annual OC World Record Stage and the 5th Annual OC World Cup, where MSI, Asus, EVGA, and ASRock teams are competing for the highest DDR4 record, Team MSI, with Kovan Yang, Toppc, Wizerty, and Lucky_n00b overclockers managed to hit DDR4-5543MHz on LN2.
You can check out the validation page over at HWBOT.org, and the overclocking was done on MSI's Z370I Gaming Pro Carbon motherboard with Intel's Core i7-8700K CPU and G.Skill's Trident Z RGB 8GB module, running at 2771.5MHz with 24-31-31-59 latencies.
This was just a record from the first day of the G.Skill OC World Record stage so there is still time for other teams to break this record or even the same team to push it even further.
Hopefully, we will hear more about it.
