MSI has announced that its entire 500 series motherboard lineup including X570, B550 & A520 products will support AMD's Smart Access Memory feature. The tech is one of the key features supported by AMD's Ryzen 5000 and Radeon RX 6000 series platform, offering a nice boost in gaming performance.
MSI Offers AMD Smart Access Memory Support Across All 500 Series (X570, B550, A520) Motherboards
ln conventional Windows-based PCs, processors can only access a fraction of graphics memory (VRAM) at once, limiting system performance. A core aspect of PCI Express technology, the Base Address Register (BAR) defines how much discrete GPU memory space is to be mapped.
With AMD Smart Access Memory, PCIe bandwidth is utilized to expand the data channel to fully harness the memory - removing the bottleneck to increasing performance. On paper, SAM can allow up an average of 6% improvement in performance and up to 11% gains in titles that make use of higher resolution textures.
MSI states that its latest Beta BIOS for its AMD 500 series chipset based motherboard lineup allows enabling of Smart Access Memory across. There are a total of 32 MSI motherboards that will get support for Smart Access Memory and the procedure to enable this is quite simple. You simply have to head over to your motherboard's support page, download and install the latest firmware which adds 'Smart Access Memory' support then head into your motherboard's BIOS to enable the feature. Following is the list of all of the supported motherboards which will be receiving the Beta BIOS update:
For MSI's 500 series motherboards, Smart Access Memory can be enabled by navigating through Settings > Advanced > PCI Subsystem Settings. Here you can find the option to enable or disable the Re-Size Bar feature. Once again, you need a Ryzen 5000 CPU and Radeon RX 6000 series GPU for this feature to work.
