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
