Intel Extreme Memory Profile DDR3 Technology

Intel® Extreme Memory Profile (Intel® XMP) DDR3 Technology: White Paper, January 2009.
With the introduction of DDR3, PC gamers and enthusiasts alike have been able to increase the performance of their PC beyond what DDR2 platforms could provide. The lowering of memory voltages and the doubling of memory clock speeds are just a few of the benefits of DDR3 over DDR2.

Intel has taken the performance envelope even further by offering the Intel® Extreme Memory Profile (Intel® XMP), which is an easy way to use an overclocking solution to an existing DDR3 implementation.

This document details the Intel® Extreme Memory Profile (XMP) DDR3 memory technology and it is intended for the enthusiast interested in learning about the Intel® XMP background, purpose, and usage.

What is Intel® XMP?
Due to the growing need for memory performance in high end gaming and performance computing, Intel engineers decided to develop a solution named the Intel Extreme Memory Profile (Intel XMP). Intel co-developed the Extreme Memory Profile (XMP) specification with its memory partners to enable performance tuning of DDR3 memory to beyond standard JEDEC SPD specifications. Simply put, the XMP profiles defined by the XMP specification are stored in the SPD of XMP DIMM and are extracted by BIOS to “tune” the memory controller for optimal memory performance..

For the user, this technology is designed to give a new or experienced over-clocker confidence to over-clock their computers with compatible hardware that will ensure a certain level of performance with DDR3 modules that are XMP compatible. So in a nutshell, Intel XMP is a performance-packed expansion of the standard DDR3 specification enabling a robust, over-clocking solution designed to take advantage of the performance features built into Intel chipsets such as the Intel® X48 Express Chipset.
