1. Set Throttling Mode
Option Values: Auto
Help Text:
Sets Thermal Throttling mode for memory, to control fans and DRAM power as needed to
control DIMM temperatures.
[Auto] – Auto Throttling Mode
[CLTM] - Closed Loop Thermal Management.
[OLTM] - Open Loop Thermal Management.
Closed Loop Thermal Management is supported only when ECC DIMM plugged. Open Loop
Thermal Management is not supported.
Comments: The Thermal Throttling Mode chosen reflects whether the DIMMs have
Temperature Sensors (TSOD), and whether the chassis is an Intel chassis for which thermal
data are available. Note that this is for thermal throttling only, independent of any controls
imposed for the purpose of power limiting.
 CLTM would be used with an OEM chassis and DIMMs with TSOD. The firmware
does not change the offset registers for closed loop during runtime, although the
Management Engine can do so.
 OLTM is intended for a system with UDIMMs which do not have TSOD. The
thermal control registers are configured during POST, and the firmware does not
change them.
