Target Server Platforms

This 128GB DDR4 module is built for Fujitsu PRIMERGY BX2560 M2, BX2580 M2, RX2530 M2, RX2540 M2 and RX2560 M2 servers. It replaces Fujitsu part numbers S26361-F3935-L517, S26361-F3935-E517, S26361-F3935-L617 and S26361-F3935-E617. The kit suits administrators expanding memory capacity in these qualified systems. It will not work in standard desktops or with unbuffered and registered ECC DIMMs.

Load-Reduced 288-Pin Form Factor

The module uses a 288-pin LRDIMM design without a heat spreader, operating at 1.2V. Load-reduced buffering reduces electrical load on the memory bus, allowing higher densities per channel. Mixing this module with unbuffered or registered ECC memory is not supported. Backward compatibility with 2133MHz operation is included for flexible deployment.

ECC Stability at DDR4 2400

CL17 latency and ECC error correction protect data integrity in continuous server workloads. The 8Rx4 organisation delivers 128GB in a single slot, maximising capacity within the platform limits. JEDEC and RoHS compliance confirms standard voltage and thermal behaviour for the qualified PRIMERGY chassis.

Questions about this item

What DDR4 speed and CAS latency does the 128GB LRDIMM run at, and what lower speed does it also support?

The module operates at DDR4 2400 (PC4-19200) with CL17 latency and is backward compatible with 2133 MHz systems.

What physical slot and form factor does this 288-pin ECC Load Reduced DIMM require?

It fits a standard 288-pin DDR4 DIMM slot in compatible Fujitsu PRIMERGY BX2560 M2, BX2580 M2, RX2530 M2, RX2540 M2 and RX2560 M2 servers.

How is the module installed and what common mixing mistake must be avoided?

Power down the server, open the chassis, align the notch with the slot key and press firmly until the latches click. Do not mix this Load Reduced ECC DIMM with unbuffered or standard registered ECC memory.
