System-Specific Server Memory Kit

This OWC kit provides 128GB of DDR4 ECC Registered memory across eight 16GB modules. It is built for Cisco UCS B420 M4 and C460 M4 servers that require registered DIMMs. The modules run at 2400 MT/s with CL17 latency at 1.2V. It is not compatible with standard desktop computers or consumer motherboards.

Verify Server Compatibility Before Ordering

Confirm that your Cisco UCS B420 M4 or C460 M4 system uses DDR4 registered ECC memory and supports 1Rx4 rank configuration. This kit will not work with unbuffered or load-reduced DIMMs and cannot be mixed with those types. Check the system documentation for maximum capacity per slot and total population rules before installation.

Replaces Cisco Part Numbers Directly

The modules replace Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG for straightforward procurement. No additional accessories or software are included in the kit. The value is the validated compatibility and JEDEC-compliant construction for immediate server deployment.
