CPU Temperature
This item displays the level of CPU temperature (High, Medium, Low) as detected
by the BIOS. The information shown in the screen is for your reference only. (See
the notes below for more information on DTS and PECI)
Low – This level is considered as the ‘normal’ operating temperature. No action is
required. The PECI count is below or equal to the processor’s DTS thermal throttle
point, minus 10 PECI counts.
Medium – The processor is running warmer. This is a ‘caution’ level and generally
means that there may be factors contributing to this condition. At this point, the PECI
count is above the processor’s DTS thermal throttle point minus 10 PECI counts,
but still below or equal to the DTS thermal throttle point.
High – The processor is running hot. Take the necessary steps to correct any heat
dissipation problems. Please check the system fans, chassis ventilation and room
temperature to correct any problems. At this point, the system fans will run at full
speed. The system’s Overheat Alarm will be triggered if the DTS thermal throttle
point is reached, plus 5 PECI counts. (This is the ‘Default Alarm Setting’. To set
the Overheat Alarm to trigger earlier with the ‘Early Alarm Setting’, refer to ‘CPU
Overheat Alarm’ on the previous page.) The system may also shut down to prevent
damage to the processor if it is not corrected. At this level, the PECI count is 0 or
above the processor’s DTS thermal throttle point.
Notes:
Supermicro does not display CPU absolute temperatures because Intel has
changed the processor methodology to PECI (Platform Environment Con-
