Thanks for all your time and patience. There are too many to list here
individually. I thought I would take a vote count.
1) /usr/platform/`uname -i`/sbin/prtdiag (13 votes)
A native command. Shows info about the processor type and speed, frequency ,
memory size of each cpu. Best results use the -v option. However this is
available only with sun4u architectures and newer. Not available on sun4c or
2) sysinfo (8 votes)
This is a utility command that can be downloaded from
There is a license to be purchased if you do not qualify as an educational
institution. This one looks very good and is just what I was looking for.

is a very old version of it available freely at http://www.sunfreeware.com
Look in the Solaris 2.5.1 section.
3) memconf (5 votes)
Another public utility script (perl) freely available at
This one also details the layout of you simm modules. A popular one.
Other commands/utilities that had mention were:
psrinfo, dmesg, memconf, Symon, prtconf, sysdef format, memtool. Sysinfo
seems to get my vote. Thanks for all your responses.
This was my query:

>Another question is , on my ultra-10 an uname -a gives me SUNW,Ultra-5_10.
>Does this mean ultra-5 or Ultra-10? What does the 5 stand for. How can I
