AMD Opteron™ Processor
1. 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.
and AMD Opteron™ Processors, order# 26094.
2. FIDVID Status Register, MSR C001_0042h.
3. StartVID and MaxVID are programmed during device manufacturing with part-specific values for Rev E and later
processors with 'Variable' indicated by the Operating Voltage OPN character, and can have one or more valid
options. All valid options for StartVID, MaxVID, and VID_VDD will be specified for the corresponding OPN.
For information on the relationship of StartVID and MaxVID to VID_VDD refer to the BIOS and Kernel
Developer’s Guide for AMD Athlon™ 64 and AMD Opteron™ Processors, order# 26094.
options. All valid options for StartVID, MaxVID, and VID_VDD will be specified for the corresponding OPN.
For information on the relationship of StartVID and MaxVID to VID_VDD refer to the BIOS and Kernel
Developer’s Guide for AMD Athlon™ 64 and AMD Opteron™ Processors, order# 26094.
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.

8. Thermal Design Power (TDP) specifications for dual core processors assume equivalent P-states (Voltage and
frequency) and equivalent Tcase conditions for both cores. Refer to the BIOS and Kernel Developer’s Guide for
AMD Athlon™ 64 and AMD Opteron™ Processors, order# 26094, for details on P-state operation for dual core
processors.
