The main memory for an HP workstation c-class can vary from a minimum of 128 MBytes
to a maximum of 2 GBytes. The workstation has eight memory card slots. Currently the
c-class workstation supports only 128 MByte and 256 MByte memory DIMM cards in
these slots.
To install DIMM cards in the c-class workstation reference "installing additional memory"
on page 141 in this Service Handbook.
CAUTION If memory is installed improperly or it is defective the c-class workstation
operating system will not boot-up, and a DIMM error will appear in the LCD.
If an error does occur, reference Chapter 3, "Troubleshooting" for additional
information.

memory failures

The HP workstation c-class operating system uses Memory Page Deallocation, a feature
that allows the system to provide information to the operating system about memory
failures.
You can use the command memrpt with the detail switch to obtain information about the
Memory Page Deallocation Table (PDT) as well as single bit errors logged by the system.
# /usr/sbin/sysdiag
DUI>logtool Enter
LOGTOOL>memrpt detail
The PDT can also be checked using the pdt command in the Service menu of the Boot
Console Handler (Refer to Chapter 6). If you replace a defective DIMM, use the Service
Menu pdt clear command to clear out the PDT.
