MSI confirms AMD EXPO technology will be used for DDR5 memory overclocking
It was reported last month that AMD will have a new technology involving DDR5 memory overclocking, applicable to both desktop and mobile platforms, called EXPO, which stands for EXTended Profiles for Overclocking. It is understood that EXPO will store two memory overclocking profiles for DDR5 memory. The first profile will be optimized for high-bandwidth usage, and the second will focus on low-latency optimization and is an optional item.

Although AMD introduced the upcoming Zen 4 architecture Ryzen 7000 series processors and AM5 platform at Computex 2022, AMD did not mention EXPO. According to VideoCardz, when MSI introduced its X670 series motherboards at Computex 2022, it confirmed the existence of EXPO technology in the slide comparing Raphael and Vermeer. The AM5 platform used in the demo is exactly the Ryzen 7000 series processor running with DDR5-6000 memory with EXPO technology turned on.

AMD’s DDR5 memory overclocking technology was originally called RAMP, and the full name is Ryzen Accelerated Memory Profile. It will be added to the preset overclocking profile of high-end memory modules to replace A-XMP in the DDR4 memory era, in response to Intel’s Alder Lake platform and its XMP 3.0
Additionally, AMD says the AM5 platform has a PCIe 5.0 lane count of 24, compared to the 28 provided by MSI. Some people speculate that the reason for the difference between AMD and MSI information is that the first Ryzen 7000 series processors using the AM5 socket only support 24 PCIe 5.0 lanes, while 28 PCIe 5.0 lanes are supported by future new processors.
