Hysteresis Temperature (Closed Loop Only)
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 (Closed Loop Only)
Use this feature to change 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 0.5oC 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
Serial Debug Message Level
This feature allows the user to set the level of debug message to be displayed. The default setting is None.
Margin Ranks
This feature allows the user to set the margin for each rank after configuring Rx DQ, TX DQ, Rx Vref, and Tx Vref settings. The options are Enabled, and Disabled.
