MSI is showing just how far DDR5 memory overclocking on AM5 can go, and the latest demo is a big one for anyone chasing high speeds without giving up capacity. Using an upcoming BIOS for the MEG X870E Unify-X MAX, MSI managed to boot a massive 128GB DDR5 setup at an eye-watering 9400 MT/s, a result that’s especially impressive because it was done with dual-rank modules.
The demonstration came from MSI’s in-house overclocker and motherboard engineer known as Toppc, who used the MEG X870E Unify-X MAX—an enthusiast-focused AM5 motherboard built specifically with memory tuning in mind. A key reason the board is popular among overclockers is its 2-DIMM layout, which typically improves signal integrity and helps push higher DDR5 frequency headroom compared to 4-DIMM designs.
For this run, the platform paired the X870E Unify-X MAX with an AMD Ryzen 5 9600X and an unreleased “1.A0B” BIOS based on AGESA 1.3.0.0. With that firmware, the system successfully booted using two 64GB double-sided, dual-rank DDR5 sticks (128GB total) at DDR5-9400. While the board can support extremely high DDR5 overclocked speeds on lower-capacity kits such as 24GB or 32GB modules—often where you’ll see the biggest headline numbers—hitting 9400 MT/s with a 2-rank 128GB configuration is a standout milestone for real-world high-capacity builds.
Toppc also suggested that this BIOS may be one of the final major upgrade steps for the current AM5 generation, noting that the next big leaps are expected alongside the next wave of Ryzen processors. That points to the upcoming Zen 6-based Ryzen lineup, which has been widely discussed in the enthusiast community and is expected to continue using the AM5 socket, potentially bringing meaningful platform-level improvements for memory overclocking and compatibility.
One of the biggest areas to watch is AMD’s future EXPO direction. Industry chatter indicates AMD is working on an updated EXPO framework that could add support for newer DDR5 module types such as CUDIMM, bringing AMD platforms closer to the latest memory technologies already being adopted elsewhere. If those changes arrive with next-generation Ryzen CPUs, it could translate into easier high-speed DDR5 tuning, better stability at extreme frequencies, and broader compatibility with cutting-edge memory kits.
The bigger takeaway is that AMD AM5 DDR5 overclocking has been accelerating quickly. Not long ago, the highest DDR5 speeds were more commonly associated with competing platforms, but recent AGESA updates and refined motherboard designs—like MSI’s X870E Unify-X MAX—are clearly closing that gap. If MSI can already boot 128GB dual-rank DDR5 at 9400 MT/s on today’s Ryzen chips with a near-term BIOS release, the next generation of Ryzen CPUs may push high-capacity, high-frequency DDR5 performance even further.
