AMD EXPO could be the key to unlocking meteoric DDR5 speeds with Zen 4

Last year, Intel introduced its new XMP 3.0 technology, which brings some new benefits to PC manufacturers with DDR5 memory in their systems. And where Intel goes, AMD will follow (or vice versa) – now it looks like AMD is poised to unleash so-called EXPO technology, for overclocking DDR5 memory, with its next-gen AM5 platform and Zen 4 chips.

EXPO supposedly stands for ‘Extended Profiles for Overclocking’ and would store two memory profiles in compatible DDR5 memory kits that would allow the memory to run faster than stock on compatible systems. That’s the rumor according to regular leaker Disclosuzen, speaking to video cardanyway.

The first profile with EXPO-compatible RAM would be optimized for high bandwidth and the second profile for low latency. While the second profile is suggested to be optional, vendors would not have to offer an option here.

AMD systems today can make use of DDR4 compatible devices XMP or AMD sister technology, AMP or X-AMP. Generally though, it’s Intel’s XMP profiles that are most commonly used, but AMD wants to change that with its next-gen memory overclocking technology.

In fact, we know this to be the case after comments made by AMD’s memory enablement manager Joseph Tao.

“Our first DDR5 platform for gaming is our Raphael platform, and one of the amazing things about Raphael is that we’re really going to try to make a big hit with overclocking,” Tao said during a webinar. “And I’ll leave it at that, but speeds you might not have thought possible might be possible with this overclocking spec.”

Other rumors suggest that AMD will be exclusively supporting DDR5 on its high-end processors, meaning DDR4 will no longer be useful for newer versions of AMD PCs.

AMD’s memory overclocking technology was originally called AMD RAMP, or ‘Ryzen Accelerated Memory Profile’. Both similarly named technologies appear in regards to memory overclocking, according to rumors and trademark documents, although it could be that they are two completely different technologies.

We’ll find out as soon as AMD’s Zen 4 processors arrive. That’s scheduled for later this year, and so far AMD seems to be sticking to that expected release window.
