SUPER MICRO Computer X8STI Throttling Open Loop, Inlet Temperature, Temperature Rise, Air Flow

X8STi/X8STi-F/X8STi-3F/X8STi-LN4 User’s Manual

Throttling - Open Loop

If set to Enabled, Throttling - Open Loop will be activated when the projected memory temperature exceeds a predefined trip-point. This process can effectively improve memory thermal performance. The options are Disabled and Enabled.

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 item allows the user to define the temperature rise parameter of a memory module to be used to improve memory power management. Each setting is in 0.5oC increments. The default setting is [020]. Press "+" or "-" on your keyboard to change this value.

Air Flow

This item allows the user to set the desired speed of air flow to the DIMM mod- ules. Each increment is one mm/sec. The default is [1500]. Press "+" or "-" on your keyboard to change this value.

Altitude

This item allows the user to specify the altitude of the location where the com- puter is used. For Tylersburg-EP platforms, system memory thermal solution is de-rated up to 900m. To comply with CPU specifications, BIOS will attempt to adjust and correct DIMM velocity based on the altitude where the system is located in order to improve DIMM thermal performance. Altitude is defined as the number of feet above the sea level where the computer is located. The options are Sea Level or Below, 1~300 (above-), 301~600 (above-), 601~900 (above-), 901~1200 (above-), 1201~1500 (above-), 1501~1800 (above-), 1801~2100 (above-), 2101~2400 (above-), 2401~2700 (above-), and 2701~3000 (above-) the sea level.

DIMM Pitch

Use this feature to specify the distance of 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.

High Performance Event Timer

Select Enabled to activate the High Performance Event Timer (HPET) that produces periodic interrupts at a much higher frequency than a Real-time Clock (RTC) does in synchronizing multimedia streams, providing smooth playback and reducing the de-
