AMD Opteron™ Processor
1. 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 AMD Functional Data Sheet, 940 Pin Package,
order# 31412, and the THERMTRIP Status Register in the BIOS and Kernel Developer’s Guide for
AMD Athlon™ 64 and AMD Opteron™ Processors, order# 26094.
order# 31412, and the THERMTRIP Status Register in the BIOS and Kernel Developer’s Guide for
AMD Athlon™ 64 and AMD Opteron™ Processors, order# 26094.
2. Tcase max is programmed during device manufacturing with part-specific values for Rev E and later processors
with 'Variable' indicated by the Case Temperature OPN character, and can be any valid Tcase max value in the
range specified for the corresponding OPN.
range specified for the corresponding OPN.
3. 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
AMD Functional Data Sheet, 940 Pin Package, order# 31412, 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.

4. The VID_VDD voltage is the VID[4:0] requested VDD supply level. Refer to the appropriate functional data
sheet for details.
5. Thermal Design Power (TDP) is measured under the conditions of Tcase Max and VDD=VID_VDD, and include
all power dissipated on-die from VDD, VDDIO, VLDT, VTT, and VDDA. Contact your Field Application
Engineer for more information on TDP specifications.

6. Thermal Design Power (TDP) and IDD max for Rev E and later processors with 'Variable' indicated by the
Operating Voltage and Case Temperature OPN characters are the limits at the highest Tcase max in the specified
range for the corresponding OPN. Products will conform to the TDP and IDD Max limits at all valid voltages. The
relationship of Tcase max and Thermal Profile to TDP for a specific device is defined in
range for the corresponding OPN. Products will conform to the TDP and IDD Max limits at all valid voltages. The
