This will give you confirmation that your trip to the BIOS was indeed successful. On this page, you’ll find “Smart Access Memory.” Here you can enable or disable the setting. Browse over to the Performance tab and open the Tuning panel. How to confirm the Smart Access Memory is on Thiago Trevisan/IDGīy using the latest version of the AMD Radeon Software, we can now confirm that Smart Access Memory is activated. The most important steps are enabling “Above 4G Decoding” and “Re-Size BAR support.” You’ll also want to make sure CSM is disabled, which is generally the default setting. If you follow the simple steps above, Smart Access Memory will be activated.

Save, exit BIOS, and reboot into Windows.

Enter your Boot menu, and disable CSM (Compatibility Support Module).

Enable “Re-Size BAR Support” (setting to Auto can also work).

If applicable, such as on Asus motherboards, enter PCIE Subsystem settings.

Enter your motherboard BIOS, typically done with Del or F2 key (see your motheboard documentation for details).

Here’s how to do that: Thiago Trevisan/IDG If you have all the right hardware, flipping on Smart Access Memory only takes a couple of minutes, though it requires delving into your motherboard BIOS. How to enable Smart Access Memory in the BIOS Smart Access Memory did show as “enabled” in the Radeon Software settings, but no conclusion as to any performance gain yet. Note: I ran a test on an AMD 5700XT, a previous generation Radeon GPU. We’ll update this article to reflect any future guidance on hardware compatibility.

If you have an Nvidia GPU or Intel CPU, Nvidia has their own version of Resizable BAR support. AMD did add select 3000 series CPUs to the mix, but you’ll still need a 500 series motherboard. AMD latest BIOS (AGESA 1.1.0.0 or newer)Īs per the recommended hardware above, best results will come from the RX 6000 series GPUs and Ryzen 5000 series CPUs.AMD Ryzen 3000 select CPUs (excluding 3200G and 3400G).AMD 500 series motherboard (X570, B550, etc.).Smart Access Memory hardware requirements Let’s get smart! (And be sure to check out our explainer on how Smart Access Memory and the Nvidia-equivalent Resizable BAR work). And lastly, we’ll show you how to confirm it’s working. Next, we’ll walk you through how to configure your BIOS to activate SAM. Before we show you how to enable Smart Access memory, we’ll discuss the hardware requirements.
