Mobile PCI Express Module

Summary

Mobile PCI Express Module (MXM) is an interconnect standard for GPUs (MXM Graphics Modules) in laptops using PCI Express created by MXM-SIG. The goal was to create a non-proprietary, industry standard socket, so one could easily upgrade the graphics processor in a laptop, without having to buy a whole new system or relying on proprietary vendor upgrades.

Generations edit

Smaller graphics modules can be inserted into larger slots, but type I and II heatsinks will not fit type III and above or vice versa.

Dell's Alienware m5700 platform uses a heatsink that will fit Type I, II, & III cards without modification.

MXM 3.1 was released in March 2012 and added PCIe 3.0 support.[1][2]

First generation modules are not compatible with second generation (MXM 3) modules and vice versa. First generation modules I to IV are fully backwards compatible.

Specification edit

MXM is no longer freely supplied by Nvidia but it is controlled by the MXM-SIG controlled by Nvidia. Only corporate clients are granted access to the standard. The MXM 2.1 specification is widely available.[citation needed]

Other uses edit

 
VIA QSM-8Q90 Qseven computer-on-module using a MXM-2 connector
 
Congatec SMARC computer-on-module using MXM-3 connector

The Qseven computer-on-module form factor uses a MXM-II connector, while the SMARC computer-on-module form factor uses a MXM 3 connector. Both implementations are not in any way compatible with the MXM standard.[citation needed]
