A single BIOS change that halves boot times on AM5 systems

Owners of modern AM5 motherboards have probably noticed that their computers take an unusually long time to boot up. The culprit is the lengthy "learning" of DDR5 memory with each boot. However, there is a simple solution, highlighted by XDA Developers in January 2026 - with the right settings in the BIOS, you can reduce the time from pressing a button to the desktop by half or more.

The main reason for slow boot times on the AM5 platform is a process called Memory Training. The motherboard checks the stability of your DDR5 memory at every boot, which can take anywhere from 30 seconds to a minute and a half, depending on the motherboard manufacturer and the speed of the memory modules (especially when using EXPO profiles). While this is safe for system stability, for most users in 2026 this is an unacceptably long wait.

The solution is Memory Context Restore (MCR). When you switch this feature from “Auto” to “Enabled” in the BIOS, the motherboard stores successful memory settings in its memory and uses them on the next boot, instead of running the entire verification process again. In many cases, boot times are reduced from 50 seconds to less than 15 seconds. To avoid possible instability or blue screens (BSODs), experts recommend that you also enable the Power Down Enable setting at the same time, which ensures proper coordination between the memory and the controller.

Where can you find these settings? For most manufacturers (Asus, MSI, Gigabyte, ASRock), they are located in the Overclocking, DRAM Configuration section or under advanced processor settings (AMD CBS). For Slovenian users who want the best experience with their Ryzen 7000 or newer processors, this intervention is almost mandatory. It is only worth noting that the function must be temporarily disabled if you replace memory modules or update the BIOS so that the system can properly “learn” the new hardware parameters again.
