Static Closed Loop Thermal Throttling (Static-CLTT):
CLTT control registers are
configured by BIOS MRC during POST. The memory throttling is run as a closed-loop
system with the DIMM temperature sensors as the control input. Otherwise, the system
does not change any of the throttling control registers in the embedded memory
controller during runtime.

Dynamic Open Loop Thermal Throttling (Dynamic-OLTT): OLTT control registers are
configured by BIOS MRC during POST. Adjustments are made to the throttling during
runtime based on changes in system cooling (fan speed).

Fan Speed Control Profiles
BIOS and BMC software work cooperatively to implement system thermal management support.
During normal system operation, the BMC will retrieve information from the BIOS and monitor
several platform thermal sensors to determine the required fan speeds.
During normal system operation, the BMC will retrieve information from the BIOS and monitor
several platform thermal sensors to determine the required fan speeds.
In order to provide the proper fan speed control for a given system configuration, the BMC must
have the appropriate platform data programmed. Platform configuration data is programmed
using the FRUSDR utility during the system integration process and by System BIOS during
run time.

System Configuration Using FRUSDR Utility
The Field Replaceable Unit and Sensor Data Record Update Utility (FRUSDR utility) is a
program used to write platform-specific configuration data to NVRAM on the server board. It
allows the user to select which supported chassis (Intel
