System Acoustic and Performance Configuration
The System Acoustic and Performance Configuration screen allows the user to configure the
thermal control behavior of the system with respect to what parameters are used in the system’s
Fan Speed Control algorithms.
To access this screen from the Main screen, select Advanced > System Acoustic and
Performance Configuration. To move to another screen, press the <Esc> key to return to the
Advanced screen, then select the desired screen.

Thermal Throttling
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 the BIOS
sends the dynamic CLTT offset temperature
data.
SCLTT will 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 that do not have TSOD. The
thermal control registers are configured
during POST, and the firmware does not
change them.
