Datasheet

Introduction

• Intel

975X Express chipset — Chipset that supports DDR2 memory technology

for the processor.

• Processor core — Processor core die with integrated L2 cache.
• LGA775 socket — The processor mates with the system board through a surface

mount, 775-land, LGA socket.

• Integrated heat spreader (IHS) —A component of the processor package used

to enhance the thermal performance of the package. Component thermal solutions

interface with the processor at the IHS surface.

• Retention mechanism (RM) — Since the LGA775 socket does not include any

mechanical features for heatsink attach, a retention mechanism is required.

Component thermal solutions should attach to the processor via a retention

mechanism that is independent of the socket.

• FSB (Front Side Bus) — The electrical interface that connects the processor to

the chipset. Also referred to as the processor system bus or the system bus. All

memory and I/O transactions as well as interrupt messages pass between the

processor and chipset over the FSB.

• Storage conditions — Refers to a non-operational state. The processor may be

installed in a platform, in a tray, or loose. Processors may be sealed in packaging or

exposed to free air. Under these conditions, processor lands should not be

connected to any supply voltages, have any I/Os biased, or receive any clocks.

Upon exposure to “free air”(i.e., unsealed packaging or a device removed from

packaging material), the processor must be handled in accordance with moisture

sensitivity labeling (MSL) as indicated on the packaging material.

• Functional operation — Refers to normal operating conditions in which all

processor specifications, including DC, AC, system bus, signal quality, mechanical

and thermal are satisfied.
