Compatible HP ProLiant ML350 Gen9 Server Memory

This 32GB kit contains two 16GB DDR4 2133MHz ECC registered DIMMs built for HP ProLiant ML350 Gen9 servers. The modules run at 1.2V with CL15 timing and use major-brand chips on a 288-pin form factor. Computer Memory Solutions validates compatibility for the listed server part numbers. A 64-bit operating system is required to address the full capacity.

Suited for ML350 Gen9 upgrades needing registered

This kit suits administrators expanding an ML350 Gen9 with registered ECC memory within the 12 slots per CPU or 24 slots with dual CPUs. Builders needing load-reduced DIMMs, non-ECC unbuffered memory, or support for a different server platform should look elsewhere. Mixing registered and load-reduced modules in the same system is not supported.

DDR4 2133MHz registered ECC with CL15 timing

The decisive specification is the DDR4 2133MHz registered ECC standard with CL15 latency. The server will clock memory down to the optimal speed allowed by the installed processor and module count. Verify the processor model and supported speeds in the ProLiant QuickSpecs before purchasing.

Questions about this item

What does the 2133 MHz rating mean once the modules are installed in the ProLiant ML350 Gen9?

The server's processor and the number of modules installed determine the actual operating speed; the memory will clock down to the highest supported frequency for that configuration.

How does the PC4-17000 designation relate to the DDR4 2133 standard used here?

PC4-17000 is the peak transfer-rate label for DDR4 2133, indicating a theoretical maximum bandwidth of 17 GB/s per module.

Will the 288-pin registered DIMMs fit the ProLiant ML350 Gen9 DIMM slots without clearance issues?

Yes, the 288-pin RDIMM form factor matches the server's DDR4 slots; the kit includes two 16 GB modules for use in the white first-slot-of-channel positions.
