Throttling - Closed Loop/Throttling - Open Loop
Throttling improves reliability and reduces power in the processor by automatic voltage control during processor idle states. Available options are Disabled and Enabled. If Enabled, the following items will appear:
Hysteresis Temperature
Temperature Hysteresis is the temperature lag (in degrees Celsius) after the set DIMM temperature threshold is reached before Closed Loop Throttling begins. The options are Disabled, 1.5oC, 3.0oC, and 6.0oC.
Guardband Temperature
This is the temperature which applies to the DIMM temperature threshold. Each step is in 0.5oC increment. The default is [006]. Press "+" or
Inlet Temperature
This is the temperature detected at the chassis inlet. Each step is in 0.5oC increment. The default is [070]. Press "+" or
Temperature Rise
This is the temperature rise to the DIMM thermal zone. Each step is in 0.5oC increment. The default is [020]. Press "+" or
Air Flow
This is the air flow speed to the DIMM modules. Each step is one mm/ sec. The default is [1500]. Press "+" or
Altitude
This feature defines how many meters above or below sea level the system is located. The options are Sea Level or Below, 1~300, 301~600, 601~900, 901~1200, 1201~1500, 1501~1800, 1801~2100, 2101~2400, 2401~2700, 2701~3000.
DIMM Pitch
This is the physical space between each DIMM module. Each step is in 1/1000 of an inch. The default is [400]. Press "+" or
