Server memory kit

This OWC kit supplies 256 GB of DDR5 ECC registered memory in eight 32 GB modules. It is built for the Dell PowerEdge R760xd2 and similar workstation or server platforms that require registered DIMMs with error correction.

Replaces Dell AC239378

The modules match Dell part numbers AC239378 and SNPW08W9C/32G, offering a direct upgrade path for systems running lower-capacity or slower registered memory. The jump is worthwhile when your workloads demand maximum DIMM population at the native 4800 MT/s speed.

Check registered DIMM requirement

Verify that your motherboard and processor support DDR5 registered ECC RDIMMs and that you are not mixing them with unbuffered or load-reduced modules. All eight slots must accept 288-pin 1.1 V modules for the kit to operate as intended.

Questions about this item

Does the 288-pin DDR5 form factor fit the PowerEdge R760xd2 memory slots?

Yes, the 288-pin DDR5 RDIMM modules are the correct form factor for the PowerEdge R760xd2 server.

What is the correct installation sequence for the eight 32GB modules?

Populate all eight slots following the R760xd2 memory population guide; the common error is leaving gaps between channels.

When should the ECC Registered RDIMM kit be replaced?

Replace modules only if system logs report correctable ECC errors rising above threshold or if a DIMM fails POST diagnostics.
