Technical Specifications

All MXM Modules are powered by the PCI 16X slot with a 5V standard power supply. MXM HE has two extra pins that are equivalent to an independent power supply in a desktop graphic card. This can be used for better protection of the MXM modules by drawing power from the system directly via the battery. MXM HE modules are mostly found in 7900GO graphics cards. The graphics cards we use on a regular basis tend to be MXM I/II/III.

The MXM slot can be used with any PCI-E device, but there are no devices that use the 16X Bus, so graphics cards should be used.

MXM is a function that has a lot of meaning. NVI DIA didn’t give it a good name. In various documents, he will be referred to as IGP or MXM. This feature is for integrated graphics chipsets which support PCI 16X bus such as Intel 915GM/945GM. Through the MXM output definition you can use a product with discrete graphics cards or integrated graphics without hardware adjustments. Some media promote “Dual Graphics”, which is a notebook that mixes LVDS and DVI signals (TMDS standard), with the Northbridge chip’s integrated display core. This allows the user to select the graphics card output signal.

Once you have this feature in place, ODMs can produce notebook computers with independent graphics cards and integrated graphics cards. This will reduce production costs.

SLI isn’t the same as dual graphics cards that are synchronized. The dual graphics card manufacturers who promote the dual graphics card outputs just want to use it to gain more attention for their products.
