Memory Configuration on ML350 G9 Server

[Z3roCool123007]

Hi there, I currently have an ML 350 G9 server with a single Processor and 2 x 16GB RAM sticks installed.

I have been given a single 32GB RAM stick for the server and wondering if this will be okay installed in the next slot (12) without another stick (So not paired). In all the server would have the 2 x 16GB DIMMS and a1 x 32GB DIMM.

Can anyone advise if this would work or should I be looking at getting 2 x 16GB DIMMS to add?

Many thanks,

Tom.

It should work as long as you make sure about this:

General memory population rules and guidelines

• A minimum of one DIMM is required per server.

• White DIMM slots denote the first slot to be populated in a channel.

• Install DIMMs only if the corresponding processor is installed.

• If only one processor is installed in a two processor system, only half of the DIMM slots are available.

• To maximize performance, it is recommended to balance the total memory capacity between allinstalled processors and load the channels similarly whenever possible.

• When two processors are installed, balance the DIMMs across the two processors.

• Place the DIMMs with the highest number of ranks in the white slot when mixing DIMMs of differentranks on the same channel.

• Do not mix RDIMMs or LRDIMMs.

• Quad rank RDIMMs are not supported in HPE ProLiant ML350 Gen9 servers.

• Quad rank LRDIMMs are capable of up to three DIMMs per channel.

• RDIMMs operating at 1.2 V

• DIMMs of different speeds may be mixed in any order; the server will select a common optimal speed.

• The maximum memory speed is a function of the memory type, memory configuration, and processormodel.

• The maximum memory capacity is a function of the memory type and number of installed processors.

• To realize the performance memory capabilities listed in this document, HPE SmartMemory is required.For additional information, see the HPE SmartMemory QuickSpecs.

• There are four (4) channels per processor; eight (8) channels per server. There are three (3) DIMMslots for each memory channel; twenty-four (24) total slots Memory channels1 and 3 consists of thethree (3) DIMMs that are furthest from the processor Memory channel 2 and 4 consists of the three (3)DIMMs that are closest to the processor
