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.
Patrol Scrubbing: A memory error-correction scheme that works in the
background looking for and correcting resident errors.
Throttling - Closed Loop/Throttling - Open Loop: Throttling improves
reliability and reduces power in the processor by automatic voltage
control during processor idle states. If Enabled, the following items will
appear:
•
Hysteresis Temperature (For 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.
• Guardband Temperature (For the Closed Loop only) - This is the
temperature which applies to the DIMM temperature threshold.
Steps are in 0.5 °C increments. The default is [006]. Press "+" or "-"
on your keyboard to change this value.
• Inlet Temperature - This is the temperature detected at the chassis
inlet. Steps are in 0.5 °C increments. 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. Steps are in 0.5 °C increments. 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.
• DIMM Pitch - This is the physical space between each DIMM
module. Each step is 1/1000 of an inch. The default is [400]. Press
"+" or "-" on your keyboard to change this value.
