Setup Utility - System Acoustic and Performance Configuration Screen Fields Setup Item Set Throttling Mode Altitude Options Auto DCLTT SCLTT SOLTT Help Text [Auto] - Auto Throttling mode. [DCLTT] - Dynamic Closed Loop Thermal Throttling [SCLTT] - Static Closed Loop Thermal Throttling [SOLTT] - Static Open Loop Thermal Throttling Comments 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. 300m or less 301m-900m 901m-1500m Higher than 1500m [300m or less] (980ft or less) Optimal performance setting near sea level. [301m - 900m] (980ft - 2950ft) Optimal performance setting at moderate elevation. [901m - 1500m] (2950ft - 4920ft) Optimal performance setting at high elevation. [Higher than 1500m] (4920ft or greater) Optimal performance setting at the highest elevations. This option sets an altitude value in order to choose a Fan Profile that is optimized for the air density at the current altitude at which the system is installed. 94 Revision 1.3 Intel order number G31608-004
