XMP (Extreme Memory Profile) is an Intel-developed technology that allows users to easily run their high-performance RAM at its advertised, higher-than-default speed. Without XMP, RAM modules typically run at a standard, lower speed, which can limit system performance.

How XMP works

When you install RAM in your computer, the system defaults to a baseline speed and timing profile called JEDEC, which is designed to ensure universal compatibility. For example, a DDR5 module rated for 6000 MHz might run at a standard JEDEC speed of 4800 MHz by default. High-performance RAM kits, intended for enthusiasts and gamers, come with pre-configured XMP profiles stored on the module itself. These profiles contain optimized settings for:

Frequency: The faster advertised speed, measured in megahertz (MHz) or megatransfers per second (MT/s).

Timings: The latency, or delay, of memory operations.

Voltage: The power needed to ensure the higher speeds are stable.

How to use XMP

To enable XMP, you must have a compatible motherboard and processor and then activate the profile in your computer's BIOS/UEFI. This is considered a form of overclocking, but because the profiles are factory-tested and certified, it is a stable and simplified way to achieve faster memory speeds.
