MSI Introduces High-Efficiency Mode to Reduce DDR5 Memory Latency
MSI has released a "High-Efficiency Mode" for its motherboards that significantly lowers latency on standard DDR5 EXPO memory modules. This feature brings performance close to that of more expensive "ULL" memory without additional cost.

MSI has announced the "High-Efficiency Mode" for its motherboards, a new feature designed to reduce latency for standard DDR5 EXPO memory modules. This update allows users to achieve performance comparable to more expensive "Ultra Low Latency" (ULL) memory kits, effectively lowering the barrier to high-speed memory performance.
The "High-Efficiency Mode" reduces the latency of standard DDR5 EXPO memory from 79.4 nanoseconds to 71.6 nanoseconds, according to MSI's internal testing. This brings the performance very close to the 71.4 nanoseconds achieved by ULL memory kits. MSI clarified that this mode does not offer significant improvements for ULL memory itself, advising existing ULL memory users against enabling it.
EXPO (Extended Profiles for Overclocking) is AMD's one-click memory overclocking technology tailored for the AM5 platform and DDR5 memory. It optimizes parameters to better suit AMD Ryzen processors. ULL memory aims for further latency reduction by tightening secondary and tertiary timings, such as tRRD, tFAW, and tWTR.
MSI's "High-Efficiency Mode" can be accessed through the MSI CLICK BIOS X under the "Overclocking" section. Users have four preset profile options: Tightest, Tighter, Balance, and Relax. This development offers a more accessible way for consumers to enhance their system's memory responsiveness without the premium price of ULL modules.
