4 Processors

The PowerEdge R920 features the Intel Xeon processor E7‐4800 v2, E7‐ 8800 v2 and E7‐2800 v2
product families with advanced reliability, availability and serviceability (RAS) features to keep your
business operations running and minimize unnecessary downtime. With its high memory capacity,
the R920 is ideal for data‐demanding, transaction‐intensive workloads, such as ERP, CRM, HPC, and
in‐memory database systems.
Processor features
Up to 15 cores in each processor
Eight DDR3 channels per socket
Up to 1600MT/s DDR3 speeds
Advanced RAS features of Intel Run Sure Technology, designed to reduce frequency and cost
of downtime while protecting data integrity. Intel Run Sure Technology provides 40 reliability
features, including:
Enhanced Machine Check Architecture Gen 1 (eMCA 1) provides advanced error log data
>
to system firmware and the OS to improve system diagnostic and predictive failure
analysis
Machine Check Architecture (MCA) recovery — Execution Path offers the capability for a
>
system to continue to operate even when the processor is unable to correct data errors
within the memory sub‐system and allows software layers to participate in system
recovery
MCA for I/O provides improved diagnostics and reduce service costs, this feature
>
provides information on uncorrected I/O errors to the OS so that it can take appropriate
actions.
PCIe Live Error Recovery (LER) can increase system uptime and extend recovery and
>
containment from PCIe errors.
Supported processors
The PowerEdge R920 supports up to four E7‐4800 v2 and E7‐8800 v2 processors, or two E7‐2800
v2 processors. Intel Xeon processors supported by the PowerEdge R920 are listed in Table 6. For the
