OWC 16GB (2x8GB) DDR3L 1333 PC3L-10600 CL9 ECC RDIMM memory upgrade

Server-Specific ECC Upgrade

This 16 GB kit consists of two 8 GB DDR3L 1333 registered DIMMs built for the Cisco UCS B230 M1. The modules operate at 1.35 V with CL9 latency and provide error-correcting code protection required by server and workstation platforms. They will not function in standard desktop computers or alongside unbuffered or load-reduced memory.

Capacity and Headroom

The dual-rank 2Rx4 organisation delivers 16 GB across two 240-pin slots, letting a compatible system reach higher multi-tasking throughput than a partially populated configuration. Bandwidth tops out at the PC3L-10600 rating, so workloads that demand faster data rates will not benefit beyond this ceiling. Buyers who need more than 16 GB per channel or higher memory speeds must choose a different platform.

Build and Connector Implications

Registered signalling and ECC circuitry add electrical buffering that stabilises dense server configurations, while the low-voltage DDR3L design reduces power draw compared to standard DDR3. The 240-pin form factor fits only DDR3L RDIMM slots keyed for registered modules, so the kit cannot be used in consumer motherboards or laptops. No heat spreader is fitted, relying on chassis airflow for cooling.
