Server-Specific ECC Upgrade

This OWC kit supplies 64 GB of DDR4 ECC registered memory in a matched pair of 32 GB modules. It is built for the Cisco UCS M2814 Compute Cartridge and will not work in standard desktop or consumer laptop platforms.

Straightforward Installation

The 288-pin RDIMMs seat like any server DIMM, but the registered buffer and ECC logic require a compatible server chipset; mixing them with unbuffered or load-reduced modules will prevent the system from posting. No heat spreaders are fitted, so airflow in dense chassis is unimpeded.

DDR4 2133 Platform Limit

The PC4-17000 rating caps transfer rate at 2133 MT/s, so bandwidth scales only with channel count and module density, not frequency. CL15 latency is fixed by the JEDEC standard for this speed grade, and 1.2 V operation is the defined ceiling for DDR4 registered parts.

Questions about this item

How can I confirm the 64GB kit is running at 2133 CL15 after installation?

Enter the server BIOS or use a hardware-information tool to verify the memory speed shows 2133 MT/s and CAS latency 15 for each 32GB module.

What ships with the 64GB upgrade kit and what must I source separately?

The kit includes two 32GB DDR4 288-pin ECC Registered RDIMM modules; no cables, tools or additional parts are required for installation.

Which capacity version matches the Cisco UCS M2814 cartridge using part numbers like 15-103025-01?

This 64GB kit (2 x 32GB) directly replaces Cisco part numbers 15-103025-01, UCSMR1X322RUA and related SKUs for the M2814 Compute Cartridge.
