Server memory for workstations and NAS

This OWC module is a single 32GB DDR5 5200 PC5-41600 CL42 2Rx8 288-pin 1.1V ECC unbuffered UDIMM. It targets workstations, servers and NAS systems that require error-correcting memory without registered buffering.

Upgrade from non-ECC or slower DDR5

The jump is worth it when data integrity matters more than raw latency, such as in file servers, virtualization hosts or ZFS-based NAS builds. Replacing standard unbuffered DDR5 adds single-bit error correction while keeping the same voltage and form factor.

Fits 288-pin DDR5 slots on compatible platforms

The module needs a motherboard that supports DDR5 ECC unbuffered UDIMMs at 1.1V and can run at 5200 MT/s or step down automatically. It frees a DIMM slot by delivering 32GB in one stick, leaving room for future expansion.

Questions about this item

What motherboard slot does the 288-pin DDR5 UDIMM require?

The module fits a standard DDR5 288-pin UDIMM slot on workstation, server, NAS or desktop boards that accept unbuffered ECC memory at 1.1 V.

Which way round does the single key notch on the 288-pin DDR5 stick go when seating it?

Align the off-centre notch with the slot key, press straight down until both side clips click — the most common error is stopping before the clips fully engage.

Does the 32 GB DDR5 5200 CL42 module need any firmware updates or battery replacements over its life?

No firmware or battery is involved; the DRAM is passive. Only reseat or replace the stick if memory errors appear after years of service.
