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.
