CPU Temperature Display (CTD)
CPU Temperature descriptions are defined as:
Low  [Tctl Value = Lowest Value, Tctl Value = -45]
Medium  [Tctl Value = -46, Tctl Value = 60]
High  [Tctl Value = -61 and Above]
Note: Only CPU temperature (Low, Medium, High) and system temperature (RT1)
are required to be displayed in BIOS and in-system monitoring software. Other
Motherboard components such as memory, chipset, SAS and 10Gb controllers,
and others are not requried to display temperatures. For debugging and testing
purposes, BIOS and system monitoring software can show motherboard
components' temperatures (such as memory, chipset, SAS and 10Gb controllers).
However for SMCI standard release version BIOS and system monitoring software,
motherboard components' temperatures are NOT required to be displayed.
CPU Overheating Alarm (COA)
CPU Overheating Alarm (COA) has
options in the BIOS, and is required to be implemented in all fan speed control
modes.
The Early Alarm is enabled when the Tctl value = 65, and is disabled when the Tctl
value drops from 65 to 62.
The Default Alarm
disabled when the Tctl value drops from 70 to 67.
When COA (either Early or Default Alarm) is enabled, the following actions are
required to be executed:
•
System overheating LED is required to be ON and to solid red.
•
Onboard buzzer or speaker is required to be ON and to be a continuous sound.
•
All system fans are required to be operated at full speed.
•
System monitoring software (such as Super Doctor and IPMI if available) is
required to report and record CPU overheating events in the event logs.
"Early
(default setting) is enabled when the Tctl value = 70, and is
