DIMM Thermal Compare Upper Limit — RO. This is the upper limit used to
compare against the DIMM's temperature. If the DIMM's temperature is greater than
this value, then the PCH's TEMP_ALERT# signal is asserted if enabled.
DIMM Thermal Compare Lower Limit — RO. This is the lower limit used to
compare against the DIMM's temperature. If the DIMM's temperature is lower than
this value, then the PCH's TEMP_ALERT# signal is asserted if enabled.
PCH Thermal Compare Upper Limit — RO. This is the upper limit used to compare
against the PCH temperature. If the PCH temperature is greater than this value, then
the PCH's TEMP_ALERT# signal is asserted if enabled.
PCH Thermal Compare Lower Limit — RO. This is the lower limit used to compare
against the PCH temperature. If the PCH temperature is lower than this value, then
the PCH's TEMP_ALERT# signal is asserted if enabled.

DIMM3 Temperature — RO. The bits contain DIMM3 temperature data in absolute
degrees Celsius.
These bits are data byte 8 provided to the external controller when it does a read over
SMLink1. Refer to Section 5.21.2
DIMM2 Temperature — RO. The bits contain DIMM2 temperature data in absolute
degrees Celsius.
These bits are data byte 7 provided to the external controller when it does a read over
SMLink1. Refer to Section 5.21.2
DIMM1 Temperature — RO. The bits contain DIMM1 temperature data in absolute
degrees Celsius.
These bits are data byte 6 provided to the external controller when it does a read over
SMLink1. Refer to Section 5.21.2
DIMM0 Temperature — RO. The bits contain DIMM0 temperature data in absolute
degrees Celsius.
These bits are data byte 5 provided to the external controller when it does a read over
SMLink1. Refer to Section 5.21.2
