About this document

This document applies to AIX Versions 4.x.


Procedure

While there is not a direct command to determine processor speed in AIX, the best place to start is with the uname command. Executing uname -m produces output of the following form:

          xxyyyyyymmss
The meanings of the placeholders are as follows:
           xx = 00
       yyyyyy = Unique CPU ID
           mm = Model ID <- these are the numbers to use to determine CPU speed
           ss = 00 (Submodel)

By cross-referencing themmvalues from the uname -m output with the table below, you can easily determine the processor speed.

NOTES:

  1. Systems where uname -m outputs a model ID of 4C:

    In general, the only way to determine the processor speed of a machine with a model ID of 4C is to reboot into System Management Services and choose the system configuration options. However, in some cases the information gained from the uname -M command can be helpful.

  2. J-Series, R-Series, and G-Series systems:

    You can determine the processor speed in an MCA SMP system from the FRU number of the CPU card by using the following command:

              lscfg -vl cpucard0 | grep FRU
    

    This will produce the following output:

              FRU Number..................C1D
    
    FRU Number    Processor Type    Processor Speed
    E1D           PowerPC 601       75
    C1D           PowerPC 601       75
    C4D           PowerPC 604       112

    X4D           PowerPC 604e      200
    
  3. E-Series and F-30 systems:

    For the E-series and F-30 systems, use the following process to determine CPU speed. Execute:

               lscfg -vp | more
    

    Look for the following stanza:

      procF0                              CPU Card
            Part Number.................093H5280
            EC Level....................00E76527
            Serial Number...............17700008
            FRU Number..................093H2431
            Displayable Message.........CPU Card
            Device Specific.(PL)........
            Device Specific.(ZA)........PS=166,PB=066,PCI=033,NP=001,CL=02,PBH
                                        Z=64467000,PM=2.5,L2=1024
            Device Specific.(RM)........10031997 140951 VIC97276
            ROS Level and ID............03071997 135048
    

    In the section Device Specific.(ZA), the section PS= (boldface here) is the processor speed in MHz.

  4. F-50 and H-50 systems and SP Silver Node:

    The following commands can be used to determine the processor speed of an F-50 system. Execute:

              lscfg -vp | more
    

    Look for the following stanza:

          Orca M5 CPU:
            Part Number.................08L1010
            EC Level....................E78405
            Serial Number...............L209034579
            FRU Number..................93H8945
            Manufacture ID..............IBM980
            Version.....................RS6K
            Displayable Message.........OrcaM5 CPU DD1.3
            Product Specific.(ZC).......PS=0013c9eb00,PB=0009e4f580,SB=0004f27
                                        ac0,NP=02,PF=461,PV=05,KV=01,CL=1
    

    In the line containing Product Specific.(ZC), the entry PS= (boldface here), is the processor speed in hexadecimal notation. To convert this to an actual speed, use the following conversions:
