Platform Management Functional Overview Intel® Server Board S1200V3RP TPS
Revision 1.2
Both Static and Dynamic CLTT modes implement a Hybrid Closed Loop Thermal Throttling
mechanism whereby the Integrated Memory Controller estimates the DRAM temperature in
between actual reads of the memory thermal sensors.
