9.3.7.3 TCASE: T
CASE
Maximum
This location provides the maximum T
CASE
for the processor. The field reflects
temperature in degrees Celsius in binary coded decimal format. The thermal
specifications are specified at the case Integrated Heat Spreader (IHS). Writes to this
register have no effect.
Example: A temperature of 66 degrees C would contain a value of 66h.
9.3.7.4 TDP: Thermal Design Power
This location contains the maximum Thermal Design Power for the part. The field
reflects power in watts in binary coded decimal format. Writes to this register have no
effect. A zero value means that the value was not programmed.
Example: A 130W TDP would be saved as 0130h.
9.3.7.5 RES7: Reserved 8
This location is reserved. Writes to this register have no effect.
