Server-grade memory kit

This OWC kit supplies 128GB of DDR4 ECC Registered memory across eight 16GB modules. It is built for Cisco UCS B260 M4 E7 v4 and B460 M4 E7 v4 servers that require registered DIMMs with error correction. Standard desktop boards cannot use this memory.

288-pin registered DIMMs

Each module uses the 288-pin DDR4 form factor and runs at 1.2V with a CL17 latency at 2400 MT/s. The registered design places a buffer on the command bus, which reduces electrical load on the memory controller in multi-DIMM server configurations. No heat spreaders are fitted, so airflow in the chassis must be sufficient for dense populations.

Eight-module population kit

The package delivers a matched set of eight 16GB sticks, allowing a single-order fill of eight slots in the supported Cisco platforms. It replaces Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG. Mixing these registered modules with unbuffered or load-reduced ECC memory is not supported.

Questions sur cet article

What speed does the DDR4 2400 PC4-19200 interface actually run at in this kit?

Each module operates at 2400 MHz with a PC4-19200 data rate and CL17 latency.

What physical slot and pin count do these 288-pin RDIMMs require?

They need a standard 288-pin DDR4 DIMM slot on a Cisco UCS B260 M4 E7 v4 or B460 M4 E7 v4 motherboard.

How are the eight 16 GB registered DIMMs installed, and what step is often missed?

Populate all eight slots following the server's channel guide; the common mistake is mixing these registered modules with unbuffered or load-reduced memory.
