8. Ensure the processor speed of the second processor (CPU 2) is the same as
the existing processor before installing the second processor.
NOTE If you are upgrading the second processor to a faster processor
speed than the primary processor, the primary processor must
also be changed. Both processors must have the same product
number, which includes the same clock speed, cache size, and
FSB speed.
The supported processors only perform at the rated speed
indicated on the processor in the HP NetServer.
