Utilizing the cutting-edge MSI MEG X870E Unify-X MAX motherboard, which is designed for enthusiasts and overclockers, Toppc demonstrated remarkable memory overclocking. Featuring a 2-DIMM layout, this motherboard supports a vast array of OC-Ready memory kits, enabling superior performance enhancements.

During the overclocking test, MSI paired the motherboard with an AMD Ryzen 5 9600X CPU and utilized the upcoming “1. A0B”BIOS, built on AGESA 1.3.0.0 firmware. This configuration successfully booted two 64 GB Dual-Rank DDR5 memory kits, totaling an impressive 128 GB of RAM, operating at a staggering speed of 9400 MT/s. This achievement is particularly noteworthy given that the motherboard can also support speeds beyond 10, 000 MT/s for 24/32 GB kits; however, achieving these speeds with a 2-rank 128 GB kit is exceptionally commendable.

According to Toppc’s post on Facebook, this marks the conclusion of substantial updates for the current AM5 series. Future updates are anticipated with the launch of the new generation of Ryzen CPUs, which are likely from the Zen 6 architecture.

Speculation around the Zen 6 Ryzen CPUs indicates they will feature up to 24 cores and maintain compatibility with the existing AM5 socketed motherboards. Another key aspect is the introduction of an updated EXPO design. Recent leaks suggest that AMD is set to debut new EXPO technology, which will provide CUDIMM support for AMD platforms.

Currently, Intel provides CUDIMM and CQDIMM support on its LGA 1851 platforms and intends to continue enhancing memory capabilities on future platforms, including Nova Lake on LGA 1954. AMD must keep pace with memory support advancements.

The gap in DDR5 speed capabilities has narrowed, as Intel previously led with modules surpassing 8000-9000 MT/s. However, with the latest AGESA BIOS updates, AMD partners like MSI now offer solid performance metrics on their current designs, and we can anticipate further enhancements in the forthcoming Ryzen generation.
