Server memory kit for enterprise upgrades

This OWC kit supplies one terabyte of DDR4 ECC registered memory across eight 128 GB modules. It is built for servers, workstations and NAS systems that require registered DIMMs with error correction. The modules run at 2400 MHz with a CAS latency of 17 and operate at 1.2 V.

Suited for registered-DIMM platforms only

The kit fits systems that accept 288-pin DDR4 RDIMMs with 4Rx4 organisation and ECC registered operation. It will not work in standard desktop computers or any platform that requires unbuffered memory. Buyers who need consumer DIMMs or a smaller capacity kit should look elsewhere.

Straightforward module installation

Each 288-pin module seats in a standard DDR4 RDIMM slot; no heat spreader is present, so clearance is minimal. The most common issue is attempting to mix these registered modules with unbuffered memory or installing them in a desktop board that does not support registered ECC. Verify the platform’s memory qualification list before fitting.

Questions about this item

What motherboard feature is required for the 288-pin DDR4 2400 ECC registered RDIMM modules to function?

A server or workstation motherboard with DDR4 RDIMM slots that support ECC registered memory at 1.2 V; standard desktop boards will not accept these modules.

Can the 4Rx4 registered DIMMs share a channel with older unbuffered ECC DIMMs already installed in the system?

No, registered and unbuffered ECC memory cannot be mixed on the same channel; all slots in a channel must use registered modules.

How can I verify the kit is running at the rated 2400 MT/s with ECC active after installation?

Enter the system BIOS or UEFI and confirm the memory speed shows 2400 MT/s, the total capacity matches the installed modules, and ECC is reported as enabled.
