Installing a Dual Processor / Replacing a Processor
HP Kayak XU800 PC Workstations have two slot 1 connectors supporting
Pentium III processors. CPU 1 includes an onboard VRM (Voltage Regulator
Module), while a VRM is required to be installed in the VRM socket when
installing a second processor.
Single processor models can be upgraded to dual processor systems by
installing a second processor accessory in the vacant processor slot. A VRM is
also included in the second processor accessory kit.
Both processors must have the same technical characteristics (speed and level-
2 cache memory capacity). Remove the processor termination card from the
processor connector slot (CPU 2). Carefully push down onto the processor until
you hear two clicks as the retention mechanism pops back, thereby locking the
processor into the processor connector. Insert the VRM (that was supplied with
the processor accessory kit) into the VRM socket (refer to the diagram on page
8 for its position on the system board).
After installation of a second processor, use the HP DualExpress! application
when upgrading Windows NT from a single-processor to a multi-processor
system. This application is included with the HP processor accessory kit.
The following table explains how to perform supported processor upgrades.
