Processor Upgrade Guidelines
•
A single processor configuration can be installed in either processor socket.
•
A single processor configuration does not require termination in the empty
socket.

Dual processors must be the same speed and same cache size.
•
Compaq recommends that dual processor configurations use Alpha
processors with the same revisions. Use the show config | more command
to determine the processor revision.
