AMD recommends Ryzen 7000 processor with DDR5-6000 memory. The default FCLK is 1733MHz
Under the blessing of EXPO memory overclocking technology, Zen 4 Ryzen 7000 series desktop processors can also achieve 1:1 FCLK frequency division under the blessing of specially optimized DDR5-6000 memory kits to achieve the best performance and latency bonding point.
It is reported that the full name of EXPO is “Extended Profiles for Overclocking” (EXtended Profiles for Overclocking), which has some similarities and differences with the existing XMP/AMP product profiles.
In addition, Robert Hallock pointed out that the memory overclocking of the Ryzen 7000 series CPU no longer needs to stick to the 1:1:1 FCLK / UCLK / MCLK parameters. For optimal performance, just focus on the automatic 1:1 FCLK division mode, and the physique of overclocking memory modules and memory controllers.
In some extreme cases, a CPU with excellent IMC physique can allow PC DIY/overclockers to achieve FCLK frequencies above 2 GHz, but obviously not everyone is so lucky.
Under native settings, DDR5-5200 memory modules will run in 2:1:1 mode (or 1733 / 2600 / 2600 frequency). For reference, the “sweet spots” for Zen 2 / Zen 3 / Zen 4 CPUs are as follows:
● Ryzen 3000 series Zen 2 CPU: DDR4-3800
● Ryzen 5000 series Zen 3 CPU: DDR4-4000
● Ryzen 7000 series Zen 4 CPU: DDR4-6000

Of course, even without a higher frequency memory, players can also start to improve the overall performance of the system in another way – that is to reduce the timing of the memory.
In this case, the DDR5-5200 @ CL28 memory kit will also be very suitable for the Zen 4 Ryzen 7000 platform.
Interestingly, according toMSI（MSI) motherboard engineer Toppc Lin revealed (portal), the EXPO memory kit will be fully compatible with the Intel XMP profile.
However, on this basis, the EXPO memory modules launched by various manufacturers can still bring more targeted optimizations to the AMD Zen 4 Ryzen 7000 platform.
Finally, the first AMD EXPO DDR5 overclocked memory modules will be available on September 27 alongside Ryzen 7000 desktop CPUs and AM5 motherboards.
As for the first 15 brands, it includesADATA（NEEDLE), American businessPirate Ship(Corsair), GEIL (GEIL), G.Skill, andKingston（Kingston）。
