AMD is preparing to migrate its Ryzen 7000 series processors and AM5 platform to the DDR5 memory standard. The red team said that with its new platform, important improvements will be offered on the memory side. A few days ago, we talked about an XMP alternative called EXPO.

Socket AM5 Ryzen 7000 series “Raphael” desktop processors will come with native support for DDR5-5200 memory speed, according to a marketing slide from memory manufacturer Apacer. Zen 4-based desktop processors will have a dual-channel DDR5 (4 sub-channels) interface, such as the 12th Gen “Alder Lake”, but will not provide backward compatibility with DDR4.

Until now, AMD relied on A-XMP, which is based on UEFI software, which adapts the Intel XMP SPD profiles of memory modules to AMD. Also, this support was being enabled by motherboard manufacturers. With the AM5 platform, this will completely change, and EXPO, a special memory module SPD extension standard to rival XMP 3.0, will arrive. The company will also make different improvements regarding its memory overclocking capabilities.

Apacer slideshow also confirms that EPYC “Genoa” processors will come with native DDR5-5200 support. Socket SP5 processors have a 12-channel DDR5 (24 sub-channel) memory interface. The Ryzen 6000 “Rembrandt” mobile processors that have already been released come with dual-channel (4 sub-channel) DDR5-4800 and LPDDR5-6400 interfaces.

Ryzen 7000 series processors that natively support DDR5-5200 will be able to run at these speeds without requiring any settings in the UEFI setup program of JEDEC PC5-42600 standard memory modules. When it comes to higher frequencies such as DDR5-6000, EXPO technology will come into play.
