Server Memory for Dell Workstations

This OWC LRDIMM module delivers 128GB of DDR4 ECC Load Reduced memory for servers, workstations and NAS systems. It replaces Dell part numbers AB445285, AB574671, SNP7JXF5C/128G and SNP7JXF5C/128VXR. The module is built for enterprise infrastructure upgrades and new builds.

Load Reduced ECC Architecture

The module uses 4Rx4 Load Reduced ECC technology at DDR4 3200 CL22 and 1.2V. This specification determines compatibility: it will not work in standard desktop computers and cannot be mixed with unbuffered or registered ECC memory. JEDEC and ROHS compliance ensures a warranty-safe upgrade.

288-Pin DDR4 Slot Requirement

Installation requires a 288-pin DDR4 slot that supports Load Reduced DIMMs. The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds. It frees capacity headroom for virtualisation and large datasets without occupying additional DIMM slots.

Questions about this item

What does the 3200MHz speed mean once this module is installed in a server?

The module runs at up to 3200MHz when the platform supports that data rate, and it will automatically clock down to 2133MHz, 2400MHz, 2666MHz or 2933MHz if the system requires a lower speed.

How does the DDR4 288-pin LRDIMM interface affect what the memory can do?

The 288-pin DDR4 LRDIMM form factor fits server and workstation boards that accept load-reduced ECC memory; it cannot be used in standard desktop PCs or mixed with unbuffered or registered DIMMs.

What physical space and slot type does this 128GB stick need to fit?

It requires a standard 288-pin DDR4 DIMM slot in a server, workstation or NAS chassis and has no heat spreader, so it fits in tight bays where taller modules might not.
