1.4.1. Intel Memory Controller Hub (MCH-M)

The Intel 845MP/845MZ MCH-M component provides the processor interface, DDR interface, AGP

interface and hub interface in an Intel 845MP/845MZ chipset platform.

The Intel MCH-M is in a 593-ball BGA package and has the following functionality:

• Supports a single Processor with a data transfer rate of 400 MHz

• Supports DDR-SDRAM at 100/133-MHZ operation (DDR200/266)
