Notes:
1.
Thermal Design Power (TDP) is measured under the conditions of T

CPUID extended function 8000_0001h fields are used by the BIOS in uniquely associating a given processor to
the P-states that are valid for that processor. Refer to the
BIOS and Kernel Developer’s Guide for
AMD Athlon 64 and AMD Opteron Processors
, order# 26094.

T
CASE
max is the maximum case temperature specification which is a physical value in degrees Celsius. This
value is programmed into Rev D and later processors. Refer to the appropriate functional data sheet, and the
THERMTRIP Status Register in the
BIOS and Kernel Developer’s Guide for AMD Athlon 64 and
AMD Opteron Processors
, order# 26094.
11.
T
CONTROL
max (maximum control temperature) is a non physical temperature on an arbitrary scale that can be
used for system thermal management policies. T
CONTROL
max represents the value at which the processor has
reached T
CASE
max when measuring the thermal diode with a dual sourcing current temperature sensor. Refer to
