Processor configurations
The PowerEdge R640 supports up to two processors and up to 28 cores per processor.
Single CPU configuration
The PowerEdge R640 functions normally if there only a single processor placed in the CPU1 socket. However, CPU and memory blanks
associated with CPU2 are required to be populated to maintain thermal efficiency. The system will not boot if only CPU2 socket is
populated. With single CPU configuration, Riser 1 (1A/1B/1C/1D) card and Riser 2B is operational.
Processor installation
For processor installation instructions, see the Dell EMC PowerEdge R640 Installation and Service Manual at Dell.com/Support/Manuals.
