  • 240-pin 2Rx4 registered DIMMs install directly in compatible slots

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.

Questions about this item

Will the 1.35V DDR3L 1333 CL9 ECC RDIMM run stably alongside existing 1.5V DDR3 modules in the Cisco UCS B230 M1?

The modules operate at 1.35V DDR3L; the Cisco UCS B230 M1 platform must support DDR3L voltage for stable mixed operation.

How can I verify the 2Rx4 ECC registered kit is detected correctly after installation?

Check the server BIOS or Cisco UCS Manager; it should show 16 GB total across two 8 GB DIMMs at 1333 MHz with ECC active.

Does the 240-pin kit include any brackets or cables, or is it only the two 8 GB RDIMMs?

The package contains only the two 8 GB 240-pin DDR3L ECC registered DIMMs; no brackets or cables are included.
