Smart Access Memory seems to be integrated into 400-series motherboards by motherboard manufacturers.
We have published a detailed article on the Smart Access Memory technology introduced by AMD with its Radeon graphics cards. According to official statements, it is necessary to use a 500 series motherboard, Ryzen 5000 processor, and RX 6000 graphics card to use this feature. However, some motherboard manufacturers will apparently unofficially bring this feature to the B450 and X470 chipsets.
This support is based on AGESA 18.104.22.168 firmware and is not yet official. The manufacturer has released an official BIOS update for 400 series motherboards to support Ryzen 5000 Desktop CPUs. It was also stated that SAM support will not be official.
AMD’s Intelligent Access Memory specification is based on PCIe standards and is called Re-size BAR (Resizeable BAR). However, it has been officially confirmed that the feature reaches its full potential through the PCIe 4.0 protocol, but can be used via the PCIe 3.0 connection. We have already reported that this technology can be used with NVIDIA and Intel components.
Before we finish, according to information from industry sources, MSI also plans to add Smart Access Memory support with a new BIOS version. If this is the case, similar moves will certainly come from names such as ASUS and Gigabyte.
