Processor Changing/Upgrading - HP Compaq dc7800 Series Technical Reference Manual

3.2.2 Processor Changing/Upgrading

All models use the LGA775 ZIF (Socket T) 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 heatsink 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 Reference Guide for processor installation instructions.
These sysems are available with one of the following processors listed in Table 3-1.
