Mobile PCI Express Module

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

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.

Some MXM cards have different mounting screw hole configurations, always check the mounting holes of the MXM card and verify that they match those of the card you plan to upgrade to.

1st generation

MXM Type	Width	Length	Connector	Module Compatibility	Thermal Compatibility	Max. Power	Max. GPU size [3]
MXM-I	70 mm	68 mm	Standard 230	I, II	I	18 W	35 × 35 mm
MXM-II	73 mm	78 mm			I, II	35 W
MXM-III	82 mm	100 mm		I, II, III	III	45 W	40 x 40 mm
MXM-III (HE)			HE 232	I, II, III, III (HE)	III, III (HE)	75 W
MXM-IV*		117 mm		I, II, III, III (HE), IV	III, III (HE), IV

*Deprecated/abandoned, became/replaced by MXM-III (HE)

2nd generation (MXM 3)

MXM Type	Width	Length	Module Compatibility	Thermal Compatibility	Max. Slot Power	GPU memory bus
MXM-A	82 mm	70 mm	A	A	55 W	64-bit or 128-bit
MXM-B		105 mm	A, B	A, B	200 W*	256-bit
MXM-B+	Not Public	Not Public	Not Public	Not Public	Not Public

*Although the slot can deliver 200 watts, it will run dangerously hot, separate power cable always used at high wattages.

Specification

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]}
