Throttling - Closed Loop/Throttling - Open Loop
Throttling improves CPU's reliability and power effi ciency via automatic voltage
control during idle states. The options are Disabled and Enabled.
If Enabled, the following items will appear:
Hysteresis Temperature (Closed Loop Only)
Temperature Hysteresis is the temperature lag (in degrees Celsius) after the
preset DIMM temperature threshold is reached before Closed Loop Throt-
tling begins. The options are Disabled, 1.5
Guardband Temperature (Closed Loop Only)
This is the temperature applied to the DIMM temperature threshold. Each
step is in 0.5oC increment. The default is [006].
Inlet Temperature
This is the temperature detected at the chassis inlet. Each step is in 0.5
increment. The default is [070].
Temperature Rise
This is the temperature rise to the DIMM thermal zone. Each step is in
o
0.5
C increment. The default is [020]. Press "+" or "-" on your keyboard to
change this value.
Air Flow
This is the air fl ow speed to the DIMM modules. Each step is one mm/sec.
The default is [1500].
Altitude
This feature defi nes 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].
North Bridge Confi guration
This feature allows the user to confi gure the settings for the North Bridge chip.
