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
