How to fix RAM XMP/EXPO Profile Boot Loop

Error code: XMP_PROFILE_BOOT_LOOP

What this error means

Enabling Intel XMP or AMD EXPO profiles causes the PC to fail POST, resulting in a series of boot loops before resetting settings to BIOS defaults. The usual suspects are incompatible RAM modules with motherboard QVL, weak memory controller (IMC) in the CPU and incorrect DRAM voltage or memory training parameters.
