Memory profile (XMP / EXPO)
Also: DOCP
A switch in the BIOS (called XMP or EXPO) that makes your memory run at the speed printed on the box.
The fuller definition
A memory profile is a set of tested speed settings stored on a RAM stick. Enabling XMP (Intel boards) or EXPO (AMD boards) in the BIOS runs the memory at its rated speed instead of a slower default.

A simplified relationship, not a screenshot or a complete design.
A concrete example
DDR5 rated at 6,000 MT/s may run at a much lower default until the profile is enabled.
The distinction that matters
Faster RAM matters for local AI only when part of the model lives in system memory.
