Chapter 4: BIOS
CPU Temperature
The 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 reaches plus 5 PECI counts. The system may also shut down to prevent dam- age to the processor if it is not corrected. At this level, the PECI count is 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- trol Interface) using DTS (Digital Thermal Sensors). Intel processors only
