Chapter 3 Processor/Memory Subsystem
The Pentium 4 processor is backward-compatible with software written for Celeron, Pentium II,
Pentium MMX, Pentium, and x86 processors.
3.2.2 PROCESSOR UPGRADING
All units use the mPGA478 ZIF mounting socket. These systems require that the processor use an
integrated heatsink/fan assembly. A replacement processor must use the same type heatsink/fan
assembly as the original to ensure proper cooling.
The FC-PGA478 package consists of the processor die mounted “upside down” on a PC board.
This arrangement allows the heat sink to come in direct contact with the processor die. The heat
sink and attachment clip are specially designed provide maximum heat transfer from the processor
component.
CAUTION: Attachment of the heatsink to the processor is critical on these systems.
!
Improper attachment of the heatsink will likely result in a thermal condition.
Although the system is designed to detect thermal conditions and automatically shut
down, such a condition could still result in damage to the processor component. Refer to
the applicable Service and Reference Guide for processor installation instructions.
CAUTION: Installing a processor that is not supported by the system board may cause
damage to the system board and/or the processor.
