OWC 128GB (8x16GB) DDR3L 1333 PC3L-10600 CL9 2Rx4 240-pin 1.35V ECC Registered RDIMM Memory Upgrade Kit

SKU CH-3MVC-STTJA

Eight 16 GB DDR3L ECC registered DIMMs deliver 128 GB at 1333 MHz CL9 for Cisco UCS B440 M2 servers

  • Capacity128GB (8 x 16GB)
  • Type240-Pin DDR3L ECC RDIMM
  • SpeedDDR3L 1333 (PC3L 10600)
  • CAS LatencyCL9
  • Voltage1.35V
  • ECCYes

Capacity 128GB (8 x 16GB)

  • 128 GB capacity across eight 16 GB modules for high-density server workloads
  • DDR3L 1333 MHz CL9 speed delivers responsive data throughput for Cisco UCS B440 M2
  • ECC registered design detects and corrects errors to protect critical workloads
  • Low 1.35 V DDR3L voltage reduces power draw in dense rack environments
  • 240-pin 2Rx4 RDIMM form factor ensures direct compatibility with Cisco part numbers A02M316GB1L, UCSMR1X162RXA.

System-specific ECC registered kit

This 128 GB kit contains eight 16 GB DDR3L 1333 registered DIMMs built for the Cisco UCS B440 M2 blade server. Each module runs at 1.35 V with CL9 latency and 2Rx4 organisation. The 240-pin form factor matches the server’s memory slots exactly. ECC registration provides the error correction and signal buffering that multi-socket server platforms require.

Server and workstation upgrades only

The modules suit administrators expanding a Cisco UCS B440 M2 or maintaining similar registered-DDR3L platforms. They will not work in standard desktop PCs, consumer laptops or any system that expects unbuffered or load-reduced memory. Buyers needing non-ECC memory, higher speeds or different pin counts should select a different kit.

Registered ECC DDR3L at 1.35 V

The decisive specification is the registered ECC DDR3L interface operating at 1.35 V. Only motherboards designed for registered DDR3L DIMMs can accept these modules; unbuffered or standard-voltage boards will not post. Verify the platform requires registered ECC DDR3L before purchasing.

Questions about this item

Will the 1333 MHz speed run at full rate in a Cisco UCS B440 M2?

The kit is rated DDR3L 1333 PC3L-10600 and is validated for the Cisco UCS B440 M2, so it will operate at its specified 1333 MHz in that server.

Does the 240-pin DDR3L RDIMM interface limit mixing with other memory types?

Yes, the registered ECC RDIMM format cannot be mixed with unbuffered or load-reduced DIMMs; all slots must use matching registered ECC modules.

What physical slot and voltage does each 16 GB module require?

Each module uses a 240-pin DDR3L slot and runs at 1.35 V, matching the Cisco UCS B440 M2 memory sockets.
