The Thermal Throttling Mode chosen reflects whether the DIMMs have
Temperature Sensors (TSOD), and whether the chassis is an Intel chassis for which thermal

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
