Processor Configurations
The Precision 7920 Rack supports up to two processors with up to 28 cores per processor.
Single CPU Configuration
The Precision 7920 Rack will function normally if there is just a single processor placed in the CPU1 socket . However, CPU and memory
blank associated with CPU2 are required to be populated for thermal reasons. The system will not boot if only CPU2 socket is populated.
With single CPU configuration all three PCIe slots in Riser 1C and PCIe slot 6 in Riser 2A will be functional.

Chipset

The Precision 7920 Rack systems use the Intel C620 chipset (Lewisburg PCH) that provides extensive I/O support. Functions and
capabilities include:
• ACPI Power Management Logic Support, Revision 4.0a
• PCI Express* Base Specification Revision 3.0
• Integrated Serial ATA host controller, supports data transfer rates of up to 6 Gb/s on all ports.
• xHCI USB controller with SuperSpeed USB 3.0 ports
• Direct Media Interface
• Serial Peripheral Interface
• Enhanced Serial Peripheral Interface
• Flexible I/O - Allows some high speed I/O signals to be configured as PCIe root ports, PCIe uplink for use with certain PCH SKUs, SATA
(and sSATA), or USB 3.0.
