Sets Thermal Throttling mode for memory, to control fans and DRAM power as needed to
control DIMM temperatures.

[DCLTT] – Dynamic Closed Loop Thermal Throttling.
[SCLTT] – Static Closed Loop Thermal Throttling.
[SOLTT] – Static Open Loop Thermal Throttling.
Comments:
Temperature Sensors (TSOD), and whether the chassis is an Intel chassis for which thermal data
are available. Note that this is for thermal throtting only, independent of any controls imposed for
the purpose of power limiting.

DCLTT is the expected mode for a board in an Intel chassis with inlet and outlet air
temperature sensors and TSOD. The firmware can update the offset registers for
closed loop during runtime, as BIOS sends the dynamic CLTT offset temperature
data.

SCLTT 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.

SOLTT 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.
