Sets Thermal Throttling mode for
memory, to control fans and DRAM
power as needed to control DIMM
temperatures.
[Auto] –BIOS selects mode.

Thermal Throttling
The Thermal Throttling Mode chosen
reflects whether the DIMMs have
Temperature Sensors (TSOD), and
whether the chassis is an Intel
®
chassis for which thermal data are
available. Note that this is for thermal
throttling only, independent of any
controls imposed for the purpose of
power limiting.
DCLTT is the expected mode for a
board in an Intel
®
chassis with inlet
and outlet air temperature sensors
and TSOD. The firmware can update
the offset registers for closed loop
during runtime, as BIOS sends the
dynamic CLTT offset temperature
data.
SCLTT would be used with an OEM
chassis and DIMMs with TSOD. The
firmware does not change the offset
registers for closed loop during
runtime, although the Management
Engine can do so.
SOLTT is intended for a system with
UDIMMs which do not have TSOD.
The thermal control registers are
configured during POST, and the
firmware does not change them.
Altitude
300m or less
301m-900m
901m-1500m
Higher than 1500m
[300m or less] (980ft or less)
Optimal performance setting near
sea level.
[301m - 900m] (980ft - 2950ft)
Optimal performance setting at
moderate elevation.
[901m – 1500m] (2950ft – 4920ft)
Optimal performance setting at high
elevation.
[Higher than 1500m] (4920ft or
greater)
Optimal performance setting at the
highest elevations.
This option sets an altitude value in
order to choose a Fan Profile that is
optimized for the air density at the
current altitude at which the system is
installed.
