BIOS fails to get the Thermal SDRs, then it uses the Memory Reference Code (MRC) default 
settings for the memory throttling settings. 
The <F2> BIOS Setup Utility provides options to set the fan profile or operating mode the 
platform will operate under. Each operating mode has a predefined profile for which specific 
platform targets are configured, which in turn determines how the system fans operate to meet 
those targets. Platform profile targets are determined by which type of platform is selected when 
running the FRUSDR utility and by the BIOS settings configured using the <F2> BIOS Setup. 
4.3.2.2.1 Fan 
Domains 
System fan speeds are controlled through pulse width modulation (PWM) signals, which are 
driven separately for each domain by integrated PWM hardware. Fan speed is changed by 
adjusting the duty-cycle, which is the percentage of time the signal is driven high in each pulse. 
Refer to Appendix D for system specific fan domains.

4.3.2.3 
Configuring the Fan Profile Using the BIOS Setup Utility  
The BIOS uses options set in the <F2> BIOS Setup Utility to determine what fan profile the 
system should operate under. These options include “THROTTLING MODE”, “ALTITUDE”, and 
“SET FAN PROFILE”. Refer to “Section 5.3.2.2.7 System Acoustic and Performance 
Configuration
” for details of the BIOS options. 
The “ALTITUDE” option is used to determine appropriate memory performance settings based 
on the different cooling capability at different altitudes. At high altitude, memory performance 
must be reduced to compensate for thinner air. Be advised, selecting an Altitude option to a 
setting that does not meet the operating altitude of the server may limit the system fans’ ability 
to provide adequate cooling to the memory. If the air flow is not sufficient to meet the needs of 
the server even after throttling has occurred, the system may shut down due to excessive 
platform thermals.  
By default, the Altitude option is set to 301 m – 900 m which is believed to cover the majority of 
the operating altitudes for these server platforms.  
You can set the “SET FAN PROFILE” option to either the Performance mode (Default) or 
Acoustics mode. Refer to the following sections for details describing the differences between 
each mode. Changing the fan profile to Acoustics mode may affect system performance. The 
“SET FAN PROFILE” BIOS option is hidden when CLTT is selected as the THROTTLING 
MODE option.
