Memory Frequency
This feature forces a DDR3 frequency slower than what the system has detected. The available options are Auto, Force DDR-
800, Force DDR-1066, and Force DDR-1333.
Memory Mode
The options are Independent, Channel Mirror, Lockstep and Sparing. Independent - All DIMMs are available to the operating
system.
Channel Mirror - The motherboard maintains two identical copies of all data in memory for redundancy.
Lockstep - The motherboard uses two areas of memory to run the same set of operations in parallel.
Sparing - A preset threshold of correctable errors is used to trigger fail-over. The spare memory is put online and used as active
memory in place of the failed memory.
Demand Scrubbing
A memory error-correction scheme where the Processor writes corrected data back into the memory block from where it was
read by the Processor. The op- tions are Enabled and Disabled.
Patrol Scrubbing
A memory error-correction scheme that works in the background looking for and correcting resident errors. The options are
Enabled and Disabled.
Throttling - Closed Loop / Throttling - Open Loop
Throttling improves reliability and reduces power in the processor by automatic voltage control during processor idle states.
Available 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 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)
This is the temperature which applies to the DIMM temperature threshold. Each step is in 0.5oC increment. The default is
[006]. Press "+" or "-" on your keyboard to change this value.
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.
