System-specific server memory

This OWC module is a 64GB DDR5 ECC Registered DIMM built for Fujitsu PRIMERGY RX2450 M2, RX2530 M7, RX2540 M7 and TX2550 M7 platforms. It will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced memory types.

Sustained-load behaviour

Rated at DDR5 5600 with CL46 latency, the module delivers consistent throughput for virtualisation, database and compute workloads. ECC and registered signalling protect data integrity during continuous operation in multi-socket servers.

Thermals and power

Operating at 1.1V without a heat spreader, the 288-pin DIMM relies on chassis airflow for cooling. The low voltage and JEDEC-standard design keep power draw modest in typical rackmount deployments.

Perguntas sobre este artigo

How much power does the 1.1 V DDR5 RDIMM draw when the server runs 24/7?

The module operates at 1.1 V, the standard JEDEC voltage for DDR5 registered DIMMs, which keeps power draw and heat low during continuous operation in compatible Fujitsu PRIMERGY servers.

What must the motherboard support for this 288-pin ECC registered DIMM to function?

The system must accept DDR5 5600 PC5-44800 registered ECC memory in a 288-pin RDIMM slot and be one of the listed Fujitsu PRIMERGY models such as RX2450 M2 or RX2530 M7.

Can this 2Rx4 CL46 module share channels with existing DDR5 RDIMMs in a Fujitsu PRIMERGY RX2540 M7?

Yes, provided the other modules are also DDR5 5600 registered ECC DIMMs; mixing with unbuffered or load-reduced memory is not supported.
