AMD’s CPU “Ryzen 7000” and each “AM5” platform have been revealed to support only DDR5 memory.
AMD Ryzen 7000 CPU and AM5 platform only support DDR5 memory, but also with EXPO technology
AMD has published a number of tips suggesting that the AM5 platform and Ryzen 7000 CPUs will be centered around the DDR5 memory standard.
More recently, at a Web seminar at Meet The Experts, AMD officials confirmed that Raphael, codenamed the Ryzen 7000 CPU with Zen 4 core architecture, will be the first DDR5 gaming platform.
Therefore, users of DDR4 memory will have to say goodbye when migrating to the new platform.
In the same Tom’s hardware report that the X670 chipset is a dual chipset design, the technology outlet states that AMD’s X670 and B650 chipset-based motherboards will be DDR5-only.
Currently, there is speculation that the lower A620 chipset will support DDR4, but the leaked AM5 feature compatibility list confirms that this socket only supports DDR5 memory, mentioning DDR4 memory. It wouldn’t be because it didn’t.
Editor from @ComputerBase posted this already a few days ago in their forum.
Socket AM5 guide, in the 254-page document you can find the text “DDR5” 76 times, “DDR4” never.

However, given AMD’s move to DDR5 in late 2022, DDR5 prices will continue to fall and availability will be incomparably better than when Intel’s 12th generation Alder Lake was launched a few months ago, so upgrade. Good news for those who are looking forward to.
However, the blue team offers users the option to choose between DDR5 and DDR4.
AMD may be in a difficult position as it doesn’t have a top option to support DDR4 memory and users have to pay a much higher price to get into the new standard.
Beyond the DDR5-only approach, AMD’s AM5 platform for Ryzen 7000 CPUs is expected to feature many new technologies.
One of them is the technology detailed by Videocardz.
Known as EXPO or Extended Profiles For Overclocking, this new feature allows you to store two memory overclocking profiles on your AM5 board, including:
- Profile optimized for high bandwidth (increased frequency)
- Profile optimized for low latency (Tighter CAS Timing)

AMD EXPO will be able to work with UDIMMs, RDIMMs, SO-DIMMs and will be able to use this technology on mobile platforms as well.
What is currently unknown is whether this technology replaces or is an extension of RAMP (Ryzen Accelerated Memory Profile), which was previously said to be on the new AMD CPU platform.
One of the great things about Raphael is that it’s about to get a lot of attention with overclocking.

It has been revealed that the trademark was filed very recently (February), and it seems that the red team will use this name.
Some monitoring and statistics software already has preliminary support for RAMP, so if AMD switches to a new EXPO brand, they may need to be updated.

Raphael + AM5 focuses on OC
Rumors have been raised for some time, but Raphael + AM5 seems to be focusing on OC.
I don’t know how much OC margin the CPU itself has, but I think that putting effort into the OC of memory means that there is a certain margin that can be OC.
There are rumors that the A620 will support DDR4, but it is denied in the article.
I agree with this, and I think Raphael’s memory controller will probably only support DDR5.
Whether or not Rembrandt will come out is subtle, but if Rembrandt comes out, it will be AM5.
The reason is that Rembrandt also has DDR5 memory.
Rembrandt doesn’t make sense to put it out on the desktop right now, so I’m wondering if APU could come from Phoenix.
Even APU is in such a state, so if A620 comes out, I think that it will be after 2023 when it is said that the price of DDR5 can be managed.
Until then, I think we will take a high-low mix strategy of Socket AM4 (low) and AM5 (high).
