Revision 1.7

Intel order number: D41763-008

3.1 Intel

5000P/5000X Memory Controller Hub (MCH)

The Memory Controller Hub (MCH) is a single 1432-pin FCBGA package, which includes the

following core platform functions:

 System Bus Interface for the processor subsystem

 Memory Controller

 PCI Express* Ports including the Enterprise Southbridge Interface (ESI)

 FBD Thermal Management

 SMBUS Interface

This section provides a high-level overview of some of these core functions as they pertain to

this server board. Additional information can be obtained from the Intel

S5000 Server Board

Family Datasheet and the Intel

5000 Series Chipset Memory Controller Hub Datasheet.

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 Intel

Xeon

processors. Each front-side bus on the MCH uses a

64-bit wide 667-MHz, 1066-MHz, or 1333-MHz data bus. The 1333-MHz data bus is capable of

transferring 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.

3.1.2 Processor Support

The server board supports the following processors:

 One or two Intel

Xeon

Processors 5000 series with a 667, 1066, or 1333-MHz front-

side bus with frequencies starting at 2.67 GHz.

 One or two Intel

Xeon

Processors 5100 series with a 1066 or 1333-MHz front-side bus

with frequencies starting at 1.60 GHz.

 One or two Intel

Xeon

Processors 5300 series with a 1066 or 1333-MHz front-side bus

with frequencies starting at 1.60 GHz.

 One or two Intel

Xeon

Processors 5200 series with a 1066 or 1333-MHz front-side bus

with frequencies starting at 1.86 GHz. – only product codes ending with “R” support this

processor series.

 One or two Intel

Xeon

Processors 5400 series with a 1066 or 1333-MHz front-side bus

with frequencies starting at 2.33 GHz. – only product codes ending with “R” support this

processor series.

Previous generations of the Intel

Xeon

Processors are not supported on the server board. For

a complete updated list of supported processors, see

. (On the Support tab, look for

“Compatibility”, and then click “Supported processor list”.).

Note: Only Intel

Xeon

processors with 667 MHz, 1066 MHz or 1333 MHz front-side bus are

supported.
