Server Memory Upgrade

This single 128GB DDR5 ECC registered DIMM is built for Fujitsu PRIMERGY RX2450 M2, RX2530 M7, RX2540 M7, TX2550 M7 and RX8770 M7 servers. It delivers 5600MHz speed with CL46 latency at 1.1V for workloads that demand error correction and registered signalling.

Installation Notes

The module uses a standard 288-pin DDR5 form factor and installs like any RDIMM, but it must not be mixed with unbuffered or load-reduced ECC memory. Buyers who need non-ECC desktop memory or who plan to combine different ECC types cannot use this part.

Capacity and Headroom

A 128GB stick provides substantial headroom for virtualisation, large databases and memory-intensive applications on supported platforms. Systems limited to lower per-slot capacities or requiring unbuffered modules will not benefit from this configuration.

Questions about this item

How can I confirm the 128GB DDR5 5600 CL46 module is running at the correct speed and timings after installation?

Enter the server BIOS or UEFI and verify the memory reports 5600 MT/s with CL46 latency; the POST screen will also show 128 GB detected per DIMM.

What comes in the box with the OWC 5R6D54R4128G and do I need any extra parts for a Fujitsu PRIMERGY RX2530 M7?

The package contains one 128 GB 288-pin DDR5 ECC Registered DIMM; no additional cables, brackets or cooling are required for the listed PRIMERGY models.

Which capacity should I choose if my Fujitsu PRIMERGY TX2550 M7 supports up to 128 GB per slot?

Select the 128 GB module to fill a single slot with the maximum supported density for that platform.
