Support for additional RAM
You're asking about how supported RAM speeds work on different motherboards. It seems you're trying to understand whether a midrange AM4 board like the B450 or B550 can actually handle 3600 MHz RAM, especially when using an XMP profile. The specs from MSI mention support up to 3200 MHz JEDEC and include 3600 MHz in its A-XMP OC settings. However, other brands such as AsRock don't list such details clearly. It looks like the motherboard might only allow 3200 MHz with manual overclocking, not automatically. So you'd need to configure it yourself for higher speeds.
