Processor Clock Rate; P5-590 And P5-595 16-Way Processor Book Diagram - IBM p5 590 System Handbook

associated L3 cache and memory are packaged on a single processor book.
Access to memory behind another processor is accomplished through the fabric
buses. The p5-590 supports up to two processor books (each book is a 16-way)
and the p5-595 supports up to four processor books. Each processor book has
dual MCMs containing POWER5 processor chips and 36 MB L3 modules. Each
16-way processor book also includes 16 slots for memory cards and six remote
I/O-2 (RIO-2) attachment cards for connection of the system I/O drawers as
shown in Figure 2-3.

2.2.6 Processor clock rate

The p5-590 system features base 8-way (CoD), 16-way, and 32-way
configurations with the POWER5 processor running at 1.65 GHz. The p5-595
system features base 16-way, 32-way, 48-way, and 64-way configurations with
the POWER5 processor running at 1.65 GHz and 1.9 GHz.
Note: Any p5-595 or p5-590 system made of more than one processor book
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
3
the command would be similar to this:
