CAUTION: Only trained service technicians are authorized to remove the system
covers and access any of the components inside the system.
CAUTION: The System Information document provides important safety and
regulatory information. Read and follow all safety instructions prior to setup,
operation, and service of your system.
To take advantage of future options in speed and functionality, you can add additional
microprocessors or replace installed microprocessors.
NOTICE: Before you add or replace a microprocessor, check the latest system BIOS
information on the Dell Support website at support.dell.com, and upgrade the BIOS if necessary.
NOTICE: The additional microprocessors must be of the same type as the primary
microprocessor. All microprocessors must also have the same L2 and L3 cache sizes.
Each microprocessor and its associated cache memory are contained in a PGA package that
is installed in a ZIF socket on the microprocessor board.
In a single-microprocessor system, the microprocessor must be installed in the CPU1 socket.
NOTE: A microprocessor and VRM must be installed in the CPU1 and VRM1 sockets,
respectively. To identify the CPU1 and VRM1 sockets, see Figure 1-1.
NOTICE: If a microprocessor socket does not have a microprocessor installed, a heat-sink
blank must be installed for that socket.
The following items are included in the microprocessor upgrade kit:
•A microprocessor
•A heat sink
•A VRM, if you are adding additional microprocessors
