128GB DDR4 LRDIMM for Fujitsu Servers

This 128GB DDR4 2933MHz ECC LRDIMM module replaces Fujitsu part numbers S26361-F4083-L929 and S26361-F4083-E929. It is built for server systems that require registered, load-reduced memory to support high-capacity configurations. The single 288-pin DIMM operates at 1.2V with a CAS latency of 21.

Load-Reduced ECC Architecture

The load-reduced design reduces electrical load on the memory bus, allowing the platform to populate more slots at rated speed than standard registered DIMMs. On-board ECC corrects single-bit errors to protect data integrity in mission-critical workloads. No heat spreader is fitted, so airflow across the module relies on the server chassis design.

Verify LRDIMM Support and Slot Population

Confirm the motherboard and BIOS explicitly support DDR4 LRDIMM modules at 2933MHz and 8Rx4 rank structure. Mixed populations with RDIMM or different rank counts may disable the slot or down-clock the channel. Check the system qualified-vendor list for the exact Fujitsu part numbers before ordering.

Questions about this item

Will the 128GB DDR4 LRDIMM need a firmware update or heat spreader added later?

The module ships without a heat spreader and requires no firmware update; install it in a compatible 288-pin DDR4 slot and the server BIOS will initialise the ECC LRDIMM automatically.

What is the first limit reached when the 2933MHz CL21 module runs at full load continuously?

The CAS latency of CL21 and the 1.20V operating voltage set the timing and power envelope; sustained throughput is bounded by the DDR4 2933 bus speed and the 8Rx4 3DS rank architecture.

How much heat and power does the 1.20V 128GB LRDIMM produce during all-day operation?

At the standard DDR4 1.20V the module draws minimal power for its density, and with no heat spreader it relies on server chassis airflow to stay within normal operating temperatures.
