CPUID extended function 8000_0001h fields are used by 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

FIDVID Status Register, MSR C001_0042h.

Ambient temperature into heat sink (internal ambient) assumed to be 42

°C.

10. TCASE 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. TCONTROL max (maximum control temperature) is a non physical temperature on an arbitrary scale that can be

used for system thermal management policies. TCONTROL max represents the value at which the processor has

reached TCASE max when measuring the thermal diode with a dual sourcing current temperature sensor. 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. Temperature is in degrees Celsius

on the TCONTROL scale.
