5000V Memory Controller Hub (MCH)
The memory controller hub (MCH) is a single 1432 pin FCBGA package that includes these
core platform functions:
System bus interface for the processor sub-system
Memory
controller
PCI Express* ports including the enterprise south bridge interface (ESI)
FBD thermal management
SMBUS
interface
3.1.1
System Bus Interface
The MCH is configured for symmetric multi-processing across two independent front side bus
interfaces that connect to the processors. Each front side bus on the MCH uses a 64-bit wide
1066- or 1333-MHz data bus. The 1333-MHz data bus can transfer data at up to 10.66 GB/s.
The MCH supports a 36-bit wide address bus, capable of addressing up to 64 GB of memory.
The MCH is the priority agent for both front side bus interfaces, and is optimized for one
processor on each bus.
