HP ProLiant DL380 G5 Server - "805 -Unsupported Processor Detected" Error on POST After Upgrading from Dual-Core to Quad-Core Processors

ISSUE:

Replacing Dual-Core with Quad-Core processors on an HP ProLiant DL380 Generation 5 (G5) Server that was purchased as a Dual-Core model results in the following Power-On Self-Test (POST) error message: 805 -Unsupported Processor Detected.

SOLUTION:

HP does not support an upgrade program (kit/option part) from Dual-Core to Quad-Core processors on ProLiant Servers. The Quad-Core processors require a different system board because Intel has announced a stepping change to the 5000 sequence chipset to provide support for future Quad-Core processors.
