Toppc showcases an AMD Ryzen CPU running DDR5 memory at 6400MT/s speeds with tight timings

A screenshot from Toppc, an overclocker from MSI, has teased what appears to be a Ryzen 7000 series AMD processor with 64GB of DDR5 memory running at 6400MT/s speeds.

On a Bilibili post, as spotted by Videocardz, Toppc has confirmed that he tested an AMD processor. This CPU is most likely a Ryzen 7000 series Zen 4 “Raphael” processor. AMD’s Ryzen 7000 series processors will be launching later this year alongside new AM5-based AMD B650, X670, and X670E series motherboards, all of which will support DDR5 memory. 

With 64GB of DDR5 memory running at 3200MHz (6400MT/s) speeds and a CAS latency of 32, TOPPC has confirmed that AMD’s upcoming Ryzen 7000 series CPUs will support fast DDR5 memory kits. That said, this test should not be seen as an indication of the maximum memory speeds that AMD’s Ryzen 7000 series processors will support.

AMD’s Ryzen 7000 series processors are expected to support DDR5 memory speeds of up to 5600 MT/s by default, with higher memory speeds being considered overclocking. 6400MT/s speeds is 800MT/s higher than this expected data rate, and support for even higher memory speeds may be possible.
