Server ECC RDIMM kit

This OWC kit supplies 512GB of DDR4 ECC Registered memory across eight 64GB modules. It is built for the HP ProLiant DL110 Gen10 Plus Telco and DL325 Gen10 Plus servers that require registered DIMMs. Standard desktop systems cannot use this memory type. Mixing with unbuffered or load-reduced modules is not supported.

Sustained load behaviour

Registered buffering places a register between the DRAM and the memory controller, reducing electrical load on the bus during continuous operation. ECC circuitry corrects single-bit errors and detects multi-bit errors without halting the system. The 1.2V operating voltage keeps power draw stable across all eight modules under full population.

Deciding specification

The modules are 288-pin DDR4 3200 CL22 2Rx4 Registered RDIMMs. Only systems that explicitly support this exact combination of speed, latency, rank architecture and registered ECC will accept the kit. Verification against the HP part numbers P43170-B21, P06035-B21, P06035-H21, P07650-B21, P07650-H21, P07650-K21 and P25205-B21 is required before purchase.

Questions about this item

What is the power draw of the 1.2 V DDR4 3200 registered kit when the server runs all day?

Each module operates at 1.2 V, the standard voltage for DDR4 registered DIMMs, and the eight 64 GB sticks together provide 512 GB of ECC registered capacity.

What must the buyer already own for this 288-pin DDR4 3200 CL22 2Rx4 kit to work?

A compatible HP ProLiant DL110 Gen10 Plus Telco or DL325 Gen10 Plus server with available 288-pin DDR4 RDIMM slots that support registered ECC memory.

Can this registered ECC DDR4 3200 kit be mixed with older unbuffered or load-reduced modules already in the server?

No, the manufacturer states that registered ECC memory cannot be mixed with unbuffered or ECC load-reduced DIMMs; all installed modules should match in type, speed and capacity.
