Server memory module

This OWC 64GB DDR4 2133 PC4-17000 CL15 ECC Load Reduced DIMM is built for Fujitsu PRIMERGY RX2530 M1-L, RX2540 M1, RX2560 M1 and RX4770 M2 servers. It delivers 64GB capacity in a single 288-pin module running at 1.2V with 4Rx4 organisation. The part replaces Fujitsu numbers S26361F3843E618, S26361-F3844-E518, S26361-F3844-E618, S26361-F3844-L518 and S26361F3843E518.

Compatibility check

Verify that your system requires DDR4 ECC Load Reduced memory and not unbuffered or standard registered DIMMs. The module cannot be mixed with other memory types and is not suitable for standard desktop computers. Confirm the server model matches the supported PRIMERGY list before ordering.

Thermals and power

The module operates at 1.2V without a heat spreader, relying on chassis airflow for cooling. Load Reduced architecture reduces electrical load on the memory bus, helping keep power draw modest in normal server workloads. No moving parts are present, so the module adds no acoustic noise.

Questions about this item

Does the 64 GB module ship alone or with extra hardware?

The module is supplied as a single 64 GB DDR4 2133 PC4-17000 CL15 4Rx4 288-pin 1.2 V ECC Load Reduced DIMM; no brackets, cables or additional parts are included.

Should I pick the 64 GB LRDIMM or a smaller registered DIMM for my PRIMERGY?

Choose this 64 GB Load Reduced DIMM when your PRIMERGY RX2530 M1-L, RX2540 M1, RX2560 M1 or RX4770 M2 requires LRDIMM technology; it cannot be mixed with registered or unbuffered modules.

What does the PC4-17000 rating deliver in a live server?

PC4-17000 indicates a 2133 MT/s data rate at CL15 latency, giving the rated bandwidth when the module runs at 1.2 V in a compatible PRIMERGY system.
