Video Cards MXM: These Unknown

In this article the public some information that I got from the internet about video cards MXM ( MPEG eXtensible Middleware ) with various specifications. Often I was confused by the myriad differences that I found on some dedicated video cards that are available with these connectors and formats but are not always compatible with each other.

But What Are The MXM Boards?

Many think that the only kind of computer desktop (the classic desktop PC, in short) have the ability to mount graphics cards ‘external’ or rather ‘dedicated’, mounted on a separate slot on the motherboard and comprising a RAM separate from everything rest of the system.

But it is not: in fact there are some laptops (laptops) or particular models (mostly gaming machines) that mount dedicated cards that use a standard called PCI Express MXM ( MPEG eXtensible Middleware ) and that through the use of GPU very high performance graphics (ATI and nVidia) fail to provide these machines high computing performance and exceptional graphics capabilities.

These cards are very high performance and have nothing to envy to the video card dedicated to desktop PCs.

How Many And What Specific Standards?

We begin by specific: there are specifications 1.3, 2.0, 2.1 and 3.0. Specifications 3.0 include video cards completely different from the previous ones both in size and slot; The following are some specifications of the various standard (source:

Consider that the rating has nothing to do with the format of the card MXM.


  • PCI Express bus with 16-way;
  • Dual LVDS panel support link;
  • VGA (analog output external);
  • 2 single connections or a Dual DVI;
  • Video out (Composite or S-Video)

Note that the functionality of the second / Dual DVI is optional and may not be available on a card with standard 1.3. In addition, most of the video cards handle up to 2 video outputs whatever combination DVI / VGA.


  • PCI Express bus with 16-way;
  • Dual LVDS panel support link;
  • VGA (analog output external);
  • 2 single connections or two double DVI;
  • HDMI support;
  • support Display Port;
  • Video out (Composite or S-Video)

Note that the support to the single DVI is mandatory and that a maximum of 3 display is supported.

MXM Formats

There are different types of format MXM each relative to the size of the card and of the mounting holes. Here is a summary:

Width Height Distance dori mounting Connector / Power (Watts)
Type I 70mm 68mm 41mm Adjust / 18W
Type II 73mm 78mm 41mm Adjust / 35W
Type III 82mm 100mm 46mm Adjust / 75W
HE 82mm 100mm 46mm HE / 75W
Type IV 82mm 117mm 46mm HE / 75W

Types MXM graphics cards

If you notice any type of card MXM connector have a similar (or regular) except the last two represented in the previous photo. In particular, the type HE shows a connector consists of 3 parts in which the last can receive extra current.

The MXM 3.0 standard with are completely different (and incompatible) compared MXM boards of previous standards. Here are two examples:

mxm board 3A

mxm board 3b

This connector is a ‘regular’ that accepts cards with two pin-outs:

Regular standard MXM connector

This below is a connector instead of HE who expects a pin made of 3 parts:

MXM connector HE

The differences between the two types of connectors are minimal: the connector HE has some additional pins with the unique feature of requiring more power to the motherboard; there are then differences except for this most current request.

Theoretically, a card type HE should work in a slot type III but the problem is the demand for energy: in fact these cards may require – under special conditions – also over 72Watt which assumes that the machine is powered by a battery pack ‘generous ‘and by a power supply seriously.

Compatibility Cards MXM

Personally I care about compatibility between cards MXM exclusively from the point of view of the repair and / or replacement in case of malfunctioning card. They ‘well known that these types of video card MXM, of any size it may be, are often subject to malfunctions and breakage.

Probably for a speech thermal (overheating) or a defect caused by the pond unleaded, very fragile, the fact is that many machines running MXM boards meet after a few years to stop working.

It ‘so interesting to see what cards are interchangeable and which search for our PC in case of board failure origin.

It must be said that these cards are generally quite expensive: a MXM type I or II can cost on the used market (assuming it is fully functional ….) Also over 120 euro. An important figure …

Usually these types of cards are on the Acer signed with a ‘G’ as an example: 5520G, 5630G, 8920G, etc. or on some models Toshina A300.

Other models fitted with cards type I or II are some iMac a few years ago, models of color white 20-inch (or even less).

The models of type III or higher usually are found in many high-performance machines, dedicated to games like some Alienware or HP HDX models with 20-inch display.
