OWC 32GB (4x8GB) DDR3L 1333 ECC Registered RDIMM for Cisco UCS B440 M2

Target Server Upgrade

This 32GB kit contains four 8GB DDR3L ECC Registered RDIMMs built for the Cisco UCS B440 M2 blade server. It is intended for administrators who need to expand memory capacity in that specific platform. The modules will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced memory types.

Capacity and Headroom

The kit delivers 32GB total across four slots, running at DDR3L 1333 (PC3L-10600) with CL9 latency and a 2Rx4 organisation. It provides headroom for virtualisation workloads and larger datasets within the supported server. Capacity is limited to the 32GB supplied; larger configurations would require additional compatible modules and available DIMM slots.

Thermals and Power

Operating at 1.35V, the low-voltage DDR3L modules draw less power than standard DDR3 equivalents. No heat spreaders are fitted, so airflow through the server chassis manages thermals. The registered buffer adds minimal overhead, keeping power draw and acoustic impact low during normal operation.
