PID: 30430 Rev 3.51 March 2006 AMD Athlon™ 64 Processor Power and Thermal Data Sheet Notes: 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 AM D Athlon™ 64 and AM D Opteron™ Processors, order# 26094. 2. FIDVID Status Register, M SR C001_0042h. 3. BIOS programs the AltVID setting into Function 3: Offset D8h. Not all systems are AltVID capable. Refer to the BIOS and Kernel Developer's Guide for AM D Athlon™ 64 and AM D Opteron™ Processors, order# 26094 for further details. 4. The VID_VDD voltage for Low Power M obile parts corresponds to 0 load (0 Amp IDD) conditions for the VID[4:0] requested VDD supply level. Refer to the AM D Functional Data Sheet, 754 Pin Package, order #31410, for details. 5. Refer to the BIOS and Kernel Developer's Guide for AM D Athlon™ 64 and AM D Opteron™ Processors, order #26094, for information on translating VID Codes to Standard or Low Power M obile Voltages. 6. Thermal Design Power (TDP) for Low Power M obile parts is measured under the conditions of Tdie M ax, IDD M ax, and VDD=VDD_dc Typ, 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. 7. Implementation of this P-state is optional in BIOS. AMD Turion™ 64 Mobile Technology 79

AMD Turion™ 64 Mobile Technology
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.
2.
FIDVID Status Register, MSR C001_0042h.
3.
BIOS programs the AltVID setting into Function 3: Offset D8h. Not all systems are AltVID capable. Refer to the
BIOS and Kernel Developer’s Guide for AMD Athlon™ 64 and AMD Opteron™ Processors, order# 26094 for
further details.
4.
The VID_VDD voltage for Low Power Mobile parts corresponds to 0 load (0 Amp IDD) conditions for the
VID[4:0] requested VDD supply level. Refer to the AMD Functional Data Sheet, 754 Pin Package, order #31410,
for details.
5.
Refer to the BIOS and Kernel Developer’s Guide for AMD Athlon™ 64 and AMD Opteron™ Processors, order
#26094, for information on translating VID Codes to Standard or Low Power Mobile Voltages.
6.
Thermal Design Power (TDP) for Low Power Mobile parts
is measured under the conditions of Tdie Max, IDD
Max, and VDD=VDD_dc Typ, 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.
7.
Implementation of this P-state is optional in BIOS.
