For those who don’t know … AMD’s EXPO stands for EXtended Profiles for Overclocking. It’s basically AMD’s answer to Intel’s XMP. Overclocking memory is so much easier than CPU overclocking … plus it will give you that extra performance at a push of a button (well, it’s more like a BIOS setting).
Taken from Videocardz … We have already shared news on AMD EXtended Profiles for Overclocking, but now it appears to be confirmed. AMD apparently decided to come up with an alternative to Intel’s XMP 3.0 overclocking profiles for DDR5 modules. However, the details are scarce, EXPO technology has only appeared in MSI X670 launch slides, while AMD did not mention this technology at all.
While AMD did not explain how EXPO works, we did get to see Ryzen 7000 CPU running alongside overclocked DDR5-6000 memory during live demos, as confirmed through launch slides footnotes.
As for the slide itself, there are a few interesting details that AMD did not share yet. Starting with 28 PCIe Gen5 lanes, while AMD claims it is actually 24. One might only guess why MSI and AMD share different information here, but it is possible that 28 lanes will be available for future SKUs, not necessary for first-gen AM5 Ryzen 7000 series.
