Chapter 7 Installing Additional Processors
72
CAUTION Do not set the processor speed switches to any other speed, as
this can result in unreliable or intermittent performance, and
data integrity may also be at risk.
l Use only processor upgrade kits with the same HP product number. This
ensures the processor type, clock speed, and cache size match, and that
product numbers are compatible.
l Ensure you install the processor module and its respective VRM in the
secondary slot, if the primary processor is already installed.
