9.2 Thermal Sensors
9.2.1 Processor PECI Temperature Sensor
The processor thermal control uses a CPU PECI thermal sensor, which is a relative
temperature off PROCHOT# trip point (a -20C reading means 20C below PROCHOT# trip point
temperature). The BMC can get the processor PECI Tcontrol values for each CPU installed to
use/follow the clamped algorithm for component thermal sensor. The following sample SDR
settings could be used:
 Use Tcontrol (byte 8, bit 0 = 1): Tcontrol value is provided by BIOS via the Set CPU
TControl command for the indicated CPU is used.
