Cisco UCS B440 M2 upgrade kit

This 32GB kit contains two 16GB DDR3L 1333 registered ECC RDIMMs built for the Cisco UCS B440 M2 blade server. The modules run at PC3L-10600 speed with CL9 latency and 1.35V operation. They are validated for workstation, server, NAS and router platforms that require registered ECC memory.

For registered ECC environments only

The kit suits administrators expanding memory in a Cisco UCS B440 M2 or compatible registered-ECC platform. It will not work in standard desktop computers, consumer laptops or any system that requires unbuffered or load-reduced DIMMs. Builders needing non-ECC or unregistered memory should look elsewhere.

32GB total in two slots

Two 16GB 2Rx4 modules fill two 240-pin slots and provide 32GB of registered ECC capacity for virtualisation, database or multi-user workloads. The registered buffer adds electrical load, so maximum capacity depends on the platform’s registered-DIMM limit rather than the module count alone.

Questions about this item

Does the Cisco UCS B440 M2 need to support DDR3L 1333 ECC Registered RDIMM memory for this kit to work?

Yes, the server must accept DDR3L 1333 PC3L-10600 CL9 2Rx4 240-pin 1.35V ECC Registered DIMMs; this kit is validated for the Cisco UCS B440 M2.

Can I keep existing unbuffered or load-reduced ECC DIMMs installed while adding these two 16GB registered modules?

No, registered ECC memory cannot be mixed with unbuffered or load-reduced ECC DIMMs; all slots must use the same registered ECC type.

How can I confirm the kit is running at 1333 MHz with ECC active after installation?

Check the BIOS memory information or the Cisco UCS Manager inventory; both will show 32 GB total at 1333 MHz with ECC Registered status.
