2.2.2 Processor clock rate

The p5-570 system features base 2-way, 4-way, 8-way, 12-way, and 16-way configurations with the POWER5 processor running at 1.5 GHz, 1.65 GHz, and 1.9 GHz. The processor card running at 1.9 GHz is available with two feature codes to support the DDR1 and DDR2 memory technology, which require two different DIMM sockets.

Note: Any system made of more than one processor card must have all processor cards running at the same speed.

To determine the processor characteristics on a running system, use one of the following commands:

lsattr -El procX Where X is the number of the processor; for example, proc0 is the first processor in the system. The output from the command3 would be similar to this:

 

type powerPC_POWER5

Processor type

False

 

frequency 165600000

Processor Speed

False

 

smt_enabled true

Processor SMT enabled False

 

smt_threads 2

Processor SMT threads

False

 

state enable

Processor state

False

 

(False, as used in this output, signifies that the value cannot be

 

changed through an AIX command interface.)

 

pmcycles -m

This command (AIX 5L Version 5.3 and later) uses the performance

 

monitor cycle counter and the processor real-time clock to measure

 

the actual processor clock speed in MHz. This is the output of a 2-way

 

p5-550 running at 1.65 GHz system:

 

Cpu 0 runs at 1656 MHz

Cpu 1 runs at 1656 MHz

Note: The pmcycles command is part of the bos.pmapi fileset. First check whether that component is installed by using the lslpp -l bos.pmapi command.

3The output of the lsattr command has been expanded with AIX 5L to include the processor clock rate.
