64 GB DDR3L ECC RDIMM kit for Cisco UCS B200 M2

This OWC upgrade kit supplies 64 GB of DDR3L 1333 memory as four 16 GB registered DIMMs. Each module runs at 1.35 V with CL9 latency and 2Rx4 organisation. The kit is built to replace Cisco part numbers A02M316GB1L, UCSMR1X162RXA, UCSMR2X162RX and UCSMR2x162RXC in the B200 M2 blade server.

Suited for server and workstation memory expansion

The modules are ECC registered DDR3L DIMMs, so they work only in platforms that require registered error-correcting memory such as the Cisco UCS B200 M2. They will not function in standard desktop computers or in systems that accept only unbuffered or load-reduced ECC memory. Builders who need unbuffered DIMMs or a different voltage should look elsewhere.

Check your blade server memory requirements

Verify that the B200 M2 is configured for DDR3L 1333 registered ECC DIMMs and that all four slots can accept 16 GB 2Rx4 modules at 1.35 V. Confirm the system BIOS supports the total 64 GB capacity and that no mixed-rank or mixed-voltage rules apply. Ensure the existing memory population matches the registered ECC specification before installing this kit.

Questions about this item

Does my Cisco UCS B200 M2 need 240-pin DDR3L slots to accept this 64GB kit?

Yes, the kit uses 240-pin DDR3L RDIMM modules and is built for the B200 M2 platform.

Can I keep my existing 16GB DDR3L 1333 ECC registered DIMMs and add these four 16GB modules?

Only if every installed module is ECC registered DDR3L 1333 at 1.35V; mixing with unbuffered or load-reduced DIMMs will prevent operation.

How do I confirm the server sees all 64GB at 1333 MHz with ECC active after installation?

Check the BIOS memory summary or Cisco UCS Manager inventory — it should report 64GB total, 1333 MT/s, and ECC enabled.
