Processor congurations
The PowerEdge R640 supports up to two processors and up to 28 cores per processor.
Single CPU conguration
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 eciency. The system will not boot if only CPU2 socket is
populated. With single CPU conguration, 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.
Chipset
The PowerEdge R640 systems use the Intel C620 chipset, which provides extensive I/O support.
The functions and capabilities of the Intel C620 chipset include:
• ACPI Power Management Logic Support, Revision 4.0a
• PCI Express Base Specication, Revision 3.0
• Integrated Serial ATA host controller, supports data transfer rates of up to 6 GB/s on all ports
