Intel® Server Board S1600JP TPS BIOS Setup Interface Table 41. Setup Utility - System Acoustic and Performance Configuration Screen Fields Setup Item Set Throttling Mode Altitude Options Auto DCLTT SCLTT SOLTT Help Text Sets Thermal Throttling mode for memory, to control fans and DRAM power as needed to control DIMM temperatures. [Auto] -BIOS selects mode. [DCLTT] - Dynamic Closed Loop Thermal Throttling [SCLTT] - Static Closed Loop Thermal Throttling [SOLTT] - Static Open Loop Thermal Throttling 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. 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) This option sets an altitude value in order to choose a Fan Profile that is Optimal performance setting near optimized for the air density at the sea level. current altitude at which the system is installed. [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. Revision 1.1 Intel Confidential 110 Intel order number G68018-002
