Installation Guidelines
• A VRM must be installed for each microprocessor installed. To locate
the VRM and microprocessor sockets, see " System Board
Components " or the interior service label.
• For single-processor operations, the processor must be installed in
socket 0 and the VRM must be installed in connector 0. Processor
socket 1 and VRM connector 1 must be empty. To locate these
components, see " System Board Components " or the interior service
label.
• For dual-processor operations, both processor sockets and both VRM
connectors must be populated.
• For dual-processor operations, the two processors and the two VRMs
must be identical. If the processors do not match, you receive a system
message , the diagnostic lights indicate an error, and the computer may
not startup. If the VRMs do not match, the diagnostic lights will
indicate an error.
• If installing a Dell processor upgrade kit for either single or dual
processors, remove and discard the original VRM(s). Then install the
VRM(s) from the upgrade kit. If you are not installing a processor
upgrade kit from Dell, reuse the original VRM(s).
• If you are upgrading your microprocessor, keep your original
microprocessor heat sink and securing clips for future trouble-
shooting.
Upgrading the Microprocessor(s)
NOTE: Dell recommends that only a technically knowledgeable person
perform this procedure.
CAUTION: The processor can get very hot during normal
operation. Be sure that the processor has had sufficient time to
cool before you touch it.
