Power and Thermal Management
7.5.1
Note: The use of external sensors that include an internal pull-up resistor on the open-drain Thermal trip
should include an Active-Low Open-Drain signal indicating an Over-Temp condition, which
remains asserted for as long as the Over-Temp Condition exists, and deasserts when temperature
has returned to within normal operating range. This External sensor output will be connected to
the GMCH input (EXTTS_0) and will trigger a Preset Interrupt and/or Read-Throttle on a level-
sensitive basis.
Additional External Thermal sensor’s outputs, for multiple sensors, can be wire-OR'ed together
allow signaling from multiple sensors located physically separately. Software can, if necessary,
distinguish which SO-DIMM(s) is the source of the over-temp through the serial interface.
However, since the SO-DIMM(s) will be located on the same System Memory Bus Data lines,
any GMCH-based Read Throttle will apply equally.
output is discouraged. However, it may be possible depending on the size of the pull-up and the
voltage of the sensor. Please refer to the Intel
Processor, and Intel
Usage
External sensor(s) used for dynamic temperature feedback control:
• Sensor on SO-DIMMs, which can be used to dynamically control read throttling.
