N-Class DIMM usable in L3000?

Hello,

do you know if I can reuse RAM from an N-Class in an L3000 server?

Hi Ralph,

I believe that they are. We have used N-Class memory in A500's and they have worked perfectly.

Hi Mike,

that sounds promising.

Although I assume that the N-class which I might have at my disposal for scrapping would be a better iron to totally replace the current L-class which needs to be upgraded RAM-wise,
I on the other hand fear that the porting of OS and app SW would be more involved than simply juggling with the DIMMs until a suitable combination is found.

Shalom,

You may want to confirm this with Hardware support or http://partsurfer.hp.com

Not everything that works is necessarily good for the machine. You may have service contract issues. I doubt that any of this will be a problem.

Re: N-Class DIMM usable in L3000?

I just tried PartSurfer and was unable to come up with a conclusive answer. My assessment on this is that the L class and N class were pretty much identical, with the N simply having more slots available for expansion. I would think the memory would be compatible in either and I think, if you check the CPUs, you'll probably find they're the same, so you won't be losing any horsepower moving your apps to the L class.

Sorry - I should have said "wouldn't lose any horsepower by leaving your apps on the L-class".

Both the L and the N came with either PA8500 or PA8600 chips rated at 360, 440 or 550 MHz. The difference being that the N could have up to 8 of them, while the L could only have 4.

Re: N-Class DIMM usable in L3000?

Hi SEP,

the provided URL for partserver is really useful.

I a locker in our data center I discovered several memory carriers of A3639 filled with 512MB DIMMs of A4923.

When I entered consecutively both prod Nos. into partserver's search form it unfortunately only came up with N-class as devices that used these parts.
So does this mean that I won't be able to use my stock memory carriers in an L3000?

If I ignored partsurfer's result however,
and installed such a carrier on the vacant 2nd slot anyway (provided the sockets matched),
would that cause damage or simply wouldn't work at worst?
I mean just in the vein of doing the dumb trial and error to see if it works.

Ralph,

If the memory is incompatible, the machine simply won't boot. You'll get some kind of error code during the self-tests and it will stop there.

Thank you Pete.
This was also my notion.

Re: N-Class DIMM usable in L3000?

I'm not sure, but the memory carriers might be slightly different. You risk to damage pins and the system board this way when you try to install the carrier for the L-class into the N-class or vice versa. Caution!

For the DIMMs it is worth to try if they work, but I guess it will work.
Please consider always the situation supported/unsupported config vs. contracted systems.

Hope this helps!
Regards
Torsten.
