Mixed size Memory on PowerEdge R730

Hello

Yes, you should be able. I suggest reviewing the memory population rules in the system manual. 32GB modules will be available in RDIMMs and LRDIMMs. You can't have more than one type of memory in the server. The module you are currently using looks to be an RDIMM, so make sure the 32GB modules are RDIMMs.

Best population would be:

32GB - 1-4
16GB - 5-12

Thanks

Thank you very much for your reply.
I'll make sure to order RDIMMs

I'm not sure I understood the part where you mentioned the best population:

32GB - 1-4   
16GB - 5-12
(what does the 1-4  and  5-12 means?)
The larger DIMMs should be the first ones to be installed?

Thanks again.

Those are the slots. The A and B lane must be identical, so there is no point in listing both A1-A4 and B1-B4. Slots 1-4 on both lanes should be populated with the 32GB modules.

Largest rank should be populated first. If all memory is the same rank then largest size modules should be populated first. This should be covered in the memory population rules/guidelines.

We can mix memory of different sizes. You can refer below link for guidelines.
