Chapter 4: AMI BIOS

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 "-" on your keyboard to change this value.

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 "-" on your keyboard to change this value.

Air Flow

This is the air flow speed to the DIMM modules. Each step is one mm/ sec. The default is [1500]. Press "+" or "-" on your keyboard to change this value.

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 "-" on your keyboard to change this value.

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.
