AMD’s EXPO tech which stands for “Extended Profiles For Overclocking” for Ryzen 7000 Desktop CPUs will be aiming for the high-end “Extreme” series 600-series motherboards in the X670 and B650 family. The profile will be an extension for XMP (Extreme Memory Profile) which will also be available on the AM5 platform but to benefit from higher speeds, AMD has designed the EXPO technology.
Based on what AMD has shown, EXPO will enable one-click DDR5 overclock support on AM5 motherboards and offer up to 11% faster performance at 1080p resolution. The EXPO memory kits from various memory makers will be designed to hit low latencies of around 63ns and there will be a range of public certification reports that will provide users with full specifications and OC settings that they can work with.
New for the Ryzen 7000 Series Desktop processors and optimized for AMD Socket AM5 motherboards, AMD EXPO technology provides users with advanced profile settings for DDR5 memory overclocking. When optimized for high-performance gaming, consumers can expect to see up to 11% faster gaming performance with AMD EXPO technology in F1® 2022.
AMD EXPO technology was designed to achieve higher gaming performance from pre-configured overclocking profiles and is easy to implement. PC enthusiasts who want to understand the finer details of an AMD EXPO technology-enabled module can find public self-certification reports, which clearly lay out the module’s full timing table, components, and the system configuration used to finalize the memory’s specifications. AMD is offering EXPO technology to its industry memory partners without royalties or licensing fees.
AMD EXPO technology arrives to market alongside the AMD Ryzen 7000 Series processors, with offerings from ADATA, Corsair, GeIL, G.SKILL, and Kingston. Over 15 AMD EXPO technology-enabled memory kits will be initially available, with memory speeds up to DDR5-6400.
As for the first EXPO products, AMD announced that their memory partners such as ADATA, Corsair, GeIL, G.Skill, and Kingston, will have a total of 15 kits at launch with speeds of up to DDR5-6400. The native speeds will be rated at:
1x1R – 5200 MT/s
We also had previously reported that DDR5-6000 will be the sweet spot for AMD Ryzen 7000 CPUs based on the Zen 4 core architecture using the EXPO technology. The DDR5-6000 memory kits that are optimized with EXPO support will offer the best performance with the lowest latency in a 1:1 FCLK mode.
Now as per Robert, we now know that the default FCLK for AMD Ryzen 7000 CPUs is set to 1733 MHz. Robert also states that memory overclocking is a little bit different with Ryzen 7000 since 1:1:1 (FCLK:UCLK:MCLK) isn’t important anymore. It is mentioned that to achieve the best results, you should leave the FCLK to auto and overclock the memory modules and memory controller in 1:1 mode. There will be some corner cases where users will be able to get better performance results by hitting over 2 GHz FCLK speeds but those aren’t a big priority, as AMD mentions.
At the native setting, DDR5-5200 will operate in a 2:1:1 mode or 1733:2600:2600 clock. Robert also confirmed something that we had stated early on that DDR5-6000 will “Roughly” the sweet spot & by sweet spot, he means the best compromise to cost/stability/performance/availability/ease. So as of right now, we have the following sweet spots as mentioned directly by AMD:
Ryzen 3000 “Zen 2” Sweet Spot – DDR4-3800 (Official AMD)
Ryzen 5000 “Zen 3” Sweet Spot – DDR4-4000 (Official AMD)
Ryzen 7000 “Zen 4” Sweet Spot – DDR5-6000 (Official AMD)
It is stated that DDR5-5200 C28 kits should go really well with Ryzen 7000 too as they are pretty fast but there aren’t a lot of kits in those configurations available right now.
As Robert states:
The reason why we say “AUTO:1:1” is now ideal because the FCLK will automatically change depending on what memory speed is in the DIMM slots. There’s no “one size fits all” ideal fabric frequency. For example: JEDEC 5300 fclk goes to 1767, 6000 RAM should go to 2000 fclk. Each memory speed has its own optimal fclk, which is why I’m gently guiding people to not worry about what the fclk is because it’s going to change with RAM speed and the AUTO setting will usually give the most performant result unless you have an astonishing overclocker.
And “get the highest possible fclk” is no longer the rule like it was on AM4. In short.
In addition to these, MSI’s in-house overclocker, TOPPC, has revealed that EXPO memory kits will be fully compatible with Intel XMP profiles. Simply put, Intel XMP memory can still support EXPO but it is worth it to have an EXPO-enabled kit to ensure the best possible profile for AMD’s Ryzen 7000 CPU lineup.

The AMD EXPO DDR5 memory kits will launch alongside the Ryzen 7000 Desktop CPUs and AM5.
