Server Memory Kit

This 32GB kit contains four 8GB DDR4 registered DIMMs built for the HP ProLiant ML350 Gen9 server. Each module runs at 2133MHz with CL15 timing and 1.2V voltage. ECC and registered buffering protect data integrity in multi-socket configurations. The 288-pin form factor fits the platform's 24 DIMM slots when two processors are installed.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller, allowing all 24 slots to be populated without signal degradation. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The modules operate at the standard 1.2V, so thermal output remains predictable under continuous utilisation. Memory speed may clock down depending on the specific processor model and total module count.

Deciding Specification

The kit is validated only for the HP ProLiant ML350 Gen9 and listed part numbers such as 754534-B21 and 765819-001. Mixing these RDIMMs with load-reduced DIMMs is not supported by the platform. A 64-bit operating system is required to address the full capacity. Buyers with different server models or desktop systems cannot use this memory.

Questions about this item

How much power does each 1.2 V registered DIMM draw when the server runs continuously?

Each module operates at 1.2 V DDR4 standard voltage; registered buffering adds minimal overhead, so total kit draw stays within the ProLiant ML350 Gen9 memory subsystem budget.

What must the system already provide for these 288-pin ECC registered sticks to function?

The server needs a DDR4 RDIMM-capable memory controller, 288-pin DIMM slots wired for registered ECC, and a 64-bit operating system to address the full 32 GB.

Will the CL15 2133 MHz modules run at rated speed beside older DDR4 DIMMs still in the chassis?

The ProLiant ML350 Gen9 clocks all populated slots to the lowest common speed; mixing slower DDR4 RDIMMs will drop the kit to that lower rate.
