Additional External Thermal sensor’s outputs, for multiple sensors, can be wire-OR'ed together to
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/MCH-based Read Throttle will apply equally.
Note: The use of external sensors that include an internal pull-up resistor on the open-drain Thermal trip
output is discouraged. However, it may be possible, depending on the size of the pull-up and the
voltage of the sensor.
