3.2.2 Processor Changing/Upgrading
These systems use the LGA1156 ZIF (Socket T) mounting socket and 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
mechanism are specially designed provide maximum heat transfer from the processor
component.
Ä
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.
Table 3-1 provides a sample listing of processors supported by these systems.
[
Ä
CAUTION: These systems can support a processor with a maximum power consumption of 95 watts.
Exceeding these limits can result in system damage and lost data.
