L2000 8600 CPU at 440 MHz

I thought PA8600 processor were 550MHz. But our L2000 Server shows the following CPU information:
From STM
Module Revision
------ --------
System Board A43938
PA 8600 CPU Module 3.0
PA 8600 CPU Module 3.0
From
echo itick_per_n_usec/U | adb -k /stand/vmunix /dev/kmem
itick_per_n_usec:
itick_per_n_usec: 440

IS there something that needs to be done to the server to have the CPUs at 550MHz ?

Don't have time to do it right the first time, but always time to do it twice

You need to upgrade your system board.
Check with HP.

hi dan,

a few things ot check are

The system board you have actually supports the 550 processors.
You need the B rev to support them.
Check the system board switches for correct settings.
What are the processors seen at at pdc level?
stop at boot and do in pr
Also I have ssen pa8600 reported as 440 and had the part number of the 440 processor on them aswell.
I was told that hp basically ran out of the pa8500, and started using 8600 proc's but set them to 440.
Dont know how truth there is in that bit but we have them here, some are pa8500 440's and some are pa8600 440's but run ok together.
And lastly is the pdc level of firmware upto date, as there were issues with processors not reported as the correct speed with earlier versions.
It could be that you have 550's and the pdc doesnt support it or the switches are set wrong on the system board.

The pa8600 had a mode where it could run like a pa8500. This let HP use pa8600 chips in place of pa8500 processors. The pa-8500 ran a multiple rates, 440 and 360 on the L2000, but 400 on one of the workstations. The L2000 system board only supported up to 440MHz. You would need to upgrade to an L3000, which has a different system board to support 550MHz processors.
The L3000 had an improved memory architecture also to support the added bandwidth needed to support faster processors.
