ASUS and MSI Roll Out UEFI Updates with AMD EXPO-ULL Memory Profile Support

Leading motherboard manufacturers ASUS and MSI have started releasing UEFI firmware updates for their AMD 600-series chipset motherboards, introducing support for the new AMD EXPO-ULL memory profiles. This development marks a significant step forward in memory configuration and performance optimization for AMD platforms.

What is AMD EXPO-ULL?

AMD EXPO-ULL (Extended Profiles for Overclocking – Ultra Low Latency) is an SPD (Serial Presence Detect) extension designed to streamline memory settings. By enabling tighter memory timings within existing speed classes, EXPO-ULL allows users to achieve improved memory performance without the complexity of manual tuning. For example, memory kits with EXPO-ULL profiles can offer DDR5-6000 at CL26 latency, compared to the more common CL30-36 at the same speed.

Firmware Updates from ASUS and MSI

ASUS has initiated the rollout with the Beta BIOS 3803 update for its AMD X670E motherboards, covering popular product lines such as ROG Crosshair, ROG Strix, ProArt, and TUF Gaming. This update not only adds support for EXPO-ULL profiles but also incorporates AGESA 1.3.0.1b, ensuring enhanced compatibility and stability.

MSI has followed suit by releasing a similar firmware update for its flagship MEG X670E GODLIKE motherboard. This update also brings EXPO-ULL support and the latest AGESA 1.3.0.1b, enabling users to take advantage of the new memory profile enhancements.

Implications for AMD Ryzen Systems

While AMD Ryzen 7000 and Ryzen 9000 series processors have traditionally lagged behind Intel counterparts in terms of maximum memory clock speeds, the introduction of EXPO-ULL opens the door for memory manufacturers to deliver kits with much tighter timings. This means users can expect better performance and responsiveness from their systems, even within the same memory speed categories.

Wider Adoption Expected

EXPO-ULL support is not limited to a specific AMD chipset generation, making it accessible to a broad range of users. As a result, more motherboard vendors are anticipated to release similar firmware updates, further expanding the availability of EXPO-ULL profiles across the AMD ecosystem.
