Cache and 533 MHz Front Side Bus datasheets chapter 5, section 5.1.2, Thermal
Diode Offset:
The thermal diode offset model specific register, THERM_DIODE_OFFSET, is located at
offset 03Fh accessed as a QWord. Bits 7:0 contain the thermal diode offset value in
0.5 °C resolution. This value should be subtracted from the diode measurement after
the thermal diode ideality adjustments are made. Values from bits 7:0 of the MSR are
interpreted as follows:
‘00000000’ = 0 °C
‘00000001’ = +0.5 °C
‘00000010’ = +1 °C
‘01111111’ = +63.5 °C
‘11111111’ = -0.5 °C
‘11111110’ = -1 °C
‘1000000’ = -64 °C
Appended to footnote of Table 5-7, Thermal Diode Specification:
Offset value is programmed in processor Model Specific Register 03Fh,
“THERM_DIODE_OFFSET”
