1.2 Processor and Chipset Overview

Built upon the functionality and capability of the Intel Xeon W series (Socket R4) processor
and the Intel C422 chipset, the X11SRi-IF motherboard provides system performance, power
efficiency, and feature sets to address the needs of next-generation computer users.
With the support of the new Intel Microarchitecture 14nm Process Technology, the X11SRi-IF
dramatically increases system performance for a multitude of server applications.
The Intel C422 chipset provides Enterprise SMBus support, including the following features:
•
DDR4 288-pin memory support
•
Support for Management Engine (ME)
•
Support of SMBus speeds of up to 400 KHz for BMC connectivity
•
SPI Enhancements
•
BMC supports remote management, virtualization, and the security package for enterprise
platforms

1.3 Special Features

Recovery from AC Power Loss

The Basic I/O System (BIOS) provides a setting that determines how the system will respond
when AC power is lost and then restored to the system. You can choose for the system to
remain powered off (in which case you must press the power switch to turn it back on), or for
it to automatically return to the power-on state. Refer to the Advanced BIOS Setup section
for this setting. The default setting is Last State.

1.4 System Health Monitoring

Onboard Voltage Monitors

An onboard voltage monitor will scan the voltages of the onboard chipset, memory, CPU,
and battery continuously. Once a voltage becomes unstable, a warning is given, or an error
message is sent to the screen. The user can adjust the voltage thresholds to define the
sensitivity of the voltage monitor.
