From the footnotes from AMD SUPPORT concerning AMD SAM:https://www.amd.com/en/gaming/technologies/smart-technologies.html
Smart Access Memory technology enablement requires an AMD Radeon 6000 series GPU, Ryzen 5000 or 3000 series CPU (excluding the Ryzen 5 3400G and Ryzen 3 3200G) and a 500 series motherboard with the latest BIOS update. For additional information and system requirements see https://www.amd.com/en/technologies/smart-access-memory. GD-178
This Windows website instructs you on how to enable AMD SAM and the System Requirements needed: https://www.windowscentral.com/how-smart-access-memory
AMD's Smart Access Memory is essentially "resizable Base Address Register (BAR) support" with a fancy name. The technology actually came along with PCIe 3.0, and AMD isn't alone in offering this feature. In early 2021, NVIDIA added resizable BAR support to its RTX 30-series GPUs through a driver update.
In order for SAM to work on your PC, you must have certain hardware components.
- GPU: AMD Radeon RX 6000 series
- CPU: AMD Ryzen 5000 series or AMD Ryzen 3000 series (excluding Ryzen 5 3400G and Ryzen 3 3200G)
- Motherboard: AMD 500 series
- Driver: Radeon Software 20.11.2 or newer
- BIOS: AMD AGESA 1.1.0.0 or newer
The above requirements might be outdated since it doesn't mention the new AM5 Motherboards or latest AMD GPUs or CPUs.
You can open a AMD SUPPORT ticket and ask them if AMD SAM can be enabled in the latest AMD GPU and CPU and AM5 Motherboards: https://www.amd.com/en/forms/contact-us/support.html
NOTE: I have a Ryzen 7 3700X with a Asus 500 Series Motherboard and I have my Nvidia GPU card enabled with SAM.
