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, 1.5° C , 3.0° C, and 6.0° C.
Guardband Temperature
This is the temperature which applies to the DIMM temperature threshold. Each step
is in 0.5° C increment. The default is [006] . Press "+" or "-" on your keyboard to
change this value.
Inlet Temperature
This is the temperature detected at the chassis inlet. Each step is in 0.5° C increment.
