Adding memory to HP3000

Adding memory to HP3000

We are upgrading the memory of our HP 3000-959. It originally had 128MB (64MB SIMMs in slots 0a and ob). Replacing the 64MB SIMMs works, but attempting to use both the 64MB and 128MB SIMMs does not. We get a FLT 7402 message. I have been told that the first 4 pairs of SIMMs must be the same size. If we put the 64MB SIMMs in 4a and 4b will that work? If not, is there any way we can use both our old and new SIMMs?

Sir, 7402 just means that you have both standard and EDO SIMMS installed on the box. I have a K210 with both installed that is running just fine.

We have our 64Mb SIMMS installed *after* all our other memory and while we get the message it works just fine and it has been blessed by HP as a supported configuration.

To Paul Courry:

The problem is that "FLT 7402" is as far as it gets. The system will not boot. If we leave a gap in the SIMM slots, will that work?

Re: Adding memory to HP3000

If you are getting FLT instead of a WARN message you may need to have the PDC firmware upgraded. The minimum rev should be 2.2. The current rev is 2.9.

The memory should be install with the larger memory SIMMs in the lowest number slots. Ideally, for maximum performance the memory should be grouped in sets of 4 SIMM but is not necessary to boot the system. Install memory from the lowest number slots to the highest.
