They are not all the same!
| MXM Type | Width | Length |
|---|---|---|
| MXM-I | 70 mm | 68mm |
| MXM-II | 73 mm | 78mm |
| MXM-III | 82 mm | 100 mm |
| MXM-IV | 82 mm | 115 mm |
| MXM-HE | 82 mm | 100 mm |
Each Type can come in two flavors: with a distance of 41mm between the mounting holes of the heatspreader or 46. The 46 version theoretically can handle larger die sizes. The rest of the card stays 100% the same. If your notebook has a 41mm card and the only upgrade available is a 46mm type, don't panic. The heatspreader are often made off solid material and can often be easily modified.
Th values for Type IV are an approximation. We also do not know what GPU sizes are supported.

Type I usually brings the low end class, such as 6200, x300,7300 and x1300 even though there are occurrences of 6600s and x600s on Type I. Because the bottom of the card is not cleared for memory, these cards are limited to 128MB. We know of no notebooks with 46mm mounting holes on Type I cards.

Please check NVIDIA's 'MXM Electromechanical Specification' for more detail.
The above listed Types should be the only MXM modules in existence. Imagine our surprise when we encountered a module that has 85 * 78 overall dimensions. Kinda like Type II and kinda like Type III but in reality nothing at all...

Technically not MXM, this card is interesting for another reason: there are 6800 versions! That means that some notebooks with Type II card that do not have the height to accommodate a 'normal' Type III may very well be able to fit in the 'Arima Special'. That is one of the reason we have them for sale in our store.
