Microprocessors
To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the
primary or secondary microprocessor.
NOTICE: The second microprocessor must be of the same type as the first. If the two microprocessors are different

Each microprocessor and its associated cache memory are contained in a PGA package that is installed in a ZIF socket on the
system board.
NOTE: A microprocessor must be installed in socket 1, and a VRM must be installed for each installed microprocessor.
To identify microprocessors and VRMs, see Figure 5-3 .
NOTE: In a single microprocessor system, the microprocessor must be installed in the PROC 1 socket.
