Memory Interchangeable

[Ragni Singh]

Can anyone tell me if memory from a L server is interchangeable to a N server. In other words, can you swap memory from a L class and put it in a N class. Any help is greatly appreciated.

I am fairly certain the memory is interchangable. The memory looks the same... I have swapped a-class memory and L-class memory, and the n-class memory looks the same.

Hope it helps

A 1GB SIMM for an L class is A5798A. The same 1GB SIMM for an N class is A4923A. This leads me to believe they're different.

Why don't you call a 3rd party memory vendor like Strategic Memory Solutions and ask them? They'd be happy to answer the question for you.

Hi Sanjay,

Sorry to tell you this, but the memory is not interchangeable.

Like John mentioned, the A-class and L-class (RP-54xx) memory is swappable but the same is not true for A & L with N-class (RP-74xx)

Yes it is swappable. It is even supported (according to the local guys). Historically, they have changed the part numbers between classes of servers with the same core technologies as part of their tier pricing. Most everybody I have ever talked to has at least had to steal from an L to meet the need on an N. We have switched both ways. Generally we steal the smaller stuff from the L's to put in the N's and populate the L's with 1Gb DIMMS.

Before anyone gets indignant about it, that is generally the way frontline Hardware manufacturers work. They figure you are shelling out money for a bigger server, so they can get you a little on the back-end over the life of the products.

The third party companies don't do this, they generally just make one part number and list it for all the same class of servers. In addition, if you are willing to do the installations yourself, you can save up to 2/3's on the cost of your memory going to Kingston/Dataram/Viking/etc to get server memory.

I hope this helps....

These questions are REALLY tough to get definitive answers to. There's apparently a "model number" underlying the "product number". The same "model number" may have multiple "product numbers", and HP does not give the same compatibility information to all parties. I once spent months getting a third-party-brokered A-class under support because it had been configured with memory for a J-class workstation. According to the HP SPI system consulted by the broker, the memory was compatible and supportable. According to the data available to Support Sales, it was not. Same model number, but two different product numbers.

No it is not technically interchangeable. Different part numbers and therefore unsupported by HP as would be any third party memory in a system you expect warrany or contract service on. Also on the internal HP parts pages list the exchange and service ordereable part numbers as different between nclass and lclass servers. Working or not, they are all SyncDRAM modules after all, it is not supported.

Straight from the HP site.
