Hi! For your AM5 build, MCR can help reduce boot times. It seems the method works best if the system has a stable power connection without interruptions. Regarding storage, MCR stores its settings in the BIOS or firmware, not directly on RAM or disks. For your 64 GB DDR5 6000 memory, you’ll need to ensure proper configuration during setup for optimal performance.

It occasionally lasts a minute or two without grid connection since capacitors need time to fully discharge. However, during a day or two outage it usually requires a retrain. The BIOS instructs the memory controller about the parameters to use. The reason for retraining after a power cut is that it can't determine if any changes occurred in the memory configuration, and it avoids getting stuck where the system fails to boot. Based on my experience, training 2x32GB of DDR5 6000 on AM5 typically takes around one minute (with a few seconds variation) on a fairly recent BIOS. This is quite lengthy for memory training, but I wouldn't consider an extra minute for turning on your computer every month or two to be problematic.

I used a 2x32GB 6000C30 card in my 7800X3D setup. The default BIOS setting was MCR off, and it took about a minute to boot after powering on. Since I usually shut down the system overnight, I typically start using it in the morning without turning it off during the day. After learning about MCR, the boot time dropped to roughly 10 seconds. At least I won’t have to worry about frequent reboots! These times refer to POST durations—the period from powering on until the screen appears before Windows loads. It’s likely saved in BIOS settings along with other configurations. The battery should keep it running until it becomes too outdated, at which point you’ll lose those BIOS tweaks.

You're asking about the implications of a motherboard entering S5 mode during shutdown without power loss. It seems you want to know if using MCR would help or if frequent memory checks are needed at startup.

You're thinking about the ASUS ROG STRIX B650E-E and wondering how often your memory training runs when MCR is active.

It's unclear if this applies generally, but I believe it occurs infrequently even in typical situations. I only recall it after a BIOS update and restarting EXPO.
