XMP or Extreme Memory Profiles, is an Intel technology that allows you to change multiple memory settings, whereas EXPO is the AMD equivalent. Both methods enable higher memory speeds simply by selecting a profile in your motherboard BIOS, providing you have the correct supported RAM.
While XMP itself has the term “Profiles” in the acronym, “XMP profiles” is the common term for different settings for different levels of RAM overclocking. Yep, we know, but the grammar police were apparently sleeping on this one.
Still, If you’ve ever wanted to overclock your memory but didn’t want to fiddle with frequency, voltage and timings, this is the way to do it.
