Appendix D. Determining CPU Speed

When using AIX 5.1 and subsequent releases, the following code returns the processor speed in hertz (Hz):

lsattr -E -l proc0 | grep "Processor Speed"

When using earlier releases than AIX 5.1, use the uname command. Running the uname -m command produces output of the following form:

xxyyyyyymmss

where:

xx

00

yyyyyy

Unique CPU ID

mm

Model ID (the numbers to use to determine CPU speed)

ss

00 (Submodel)

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

1. For systems where the uname -m command 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, as shown in the following table.

2. For 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
   FRU Number    Processor Type    Processor Speed
        E1D           PowerPC 601       75
        C1D           PowerPC 601       75

        E4D           PowerPC 604       112
        X4D           PowerPC 604e      200

3. For the E-series and F-30 systems use the following command to determine CPU speed:

   # lscfg -vp | pg

   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= is the processor speed expressed in MHz.

4. For 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:

   # 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= is the processor speed in hexadecimal notation. To convert this to an actual speed, use the following conversions:

   0009E4F580 = 166 MHz
   0013C9EB00 = 332 MHz

   The value PF= indicates the processor configuration.

   251 = 1 way 166 MHz
   261 = 2 way 166 MHz
   451 = 1 way 332 MHz
   461 = 2 way 332 MHz
