Unfortunately, AMD Ryzen 5000 does NOT support DDR5 RAM. They are neither designed around the DDR5 specifications nor can they be upgraded to support DDR5.
In the following text, I will further detail the answer to the question whether AMD Ryzen 5000 supports DDR5 or not by looking at its specifications in detail.
I will also talk about the fact that RAM sticks and slots are simply not backwards or forward compatible.
AMD Ryzen 5000 RAM Specifications
All Ryzen 5000 CPUs for desktops as well as for laptops support DDR4 RAM.
The following images show the specifications for AMD Ryzen 7 5700X (CPU without iGPU) as well as for AMD Ryzen 7 5700G (CPU with iGPU(.
You can see that both high performance Ryzen 5000 CPUs support DDR4 RAM only.
You can also see the rest of specifications including the fact that 5000 series ONLY supports dual channel memory as well as a stock memory configuration of upto 3200MHz only (overclocking RAM is also supported).
So Does Ryzen 5000 Support DDR5?
It should be fairly clear from the specifications alone that AMD Ryzen 5000 CPUs DO NOT support DDR5.
You can further see this from the motherboard specifications themselves. The motherboard chipsets that support the 5000 series AMD CPUs i.e the X570, B550 and A520, have DDR4 RAM slots.
Hence, even physically speaking, you cannot plug DDR5 RAM into the motherboards intended for Ryzen 5000 CPUs.
RAM sticks are NOT Forward or Backwards Compatible
You cannot put a DDR5 RAM in a DDR4 motherboard and vice versa.
There are a few important reasons to this:
- RAM sticks have different physical profile across generation
- RAM sticks have different voltage requirement across generation
- Each RAM generation requires a different controller

Which Motherboards and CPUs Currently Support DDR5 RAM?
Currently, only the newest generation of CPUs and motherboard chipset support DDR5 RAM.
The Intel 12th Generation CPUs and Intel 600 series motherboard chipsets are the first to support DDR5 RAM.

Which AMD CPUs Support DDR5 RAM?
With AMD, the laptop line of CPUs has a head start in terms of supporting DDR5 RAM.
6000 Series CPUs for Laptops Support DDR5
Currently the 6000 series Zen3+ based laptop CPUs, ranging from AMD Ryzen 5 6600U all the way to AMD Ryzen 9 Pro 6950HS support DDR5 RAM.
Unfortunately, there are no desktop based 6000 series CPUs.
In fact, for desktops, AMD will skip the 6000 series and go directly for the 7000 series CPUs.
7000 Series AMD CPUs for Desktops Support DDR5
The 7000 series CPU based on the Zen 4 architecture will feature a long list of upgrades including support for DDR5 RAM.
The other important upgrades will include support for PCIe 5.0, the new AM5 socket, 5nm transistor size as well as speeds of more than 5.5 GHz per core.
It also goes without saying that these CPUs will unleash a new series of AMD chipset, the 600 series chipsets.
Additionally, since the RAM sticks are NOT backwards compatible, DDR4 RAM sticks will NOT work with the new 7000 series AMD CPUs.
Does AMD Ryzen Have DDR5 Support?
As discussed earlier, AMD has started their DDR5 support with Ryzen 6000 series CPU on laptops.
On desktops, the 7000 series will support DDR5.
Does Ryzen 7 5800X Support DDR5?
No, despite being a high performance CPU, the Ryzen 7 5800X DOES NOT support DDR5. None of the 5000 series CPUs support DDR5 RAM.
Does Ryzen 9 5950X Support DDR5?
No, Ryzen 9 5950X DOES NOT support DDR5 RAM for reasons explained earlier.
