Targeted Server Upgrade

This 16GB DDR3L ECC Registered RDIMM is built for Cisco UCS C24 M3, C240 M3 and C420 M3 servers. It serves administrators who need to extend the life of existing infrastructure with validated, single-module capacity. The module is not compatible with standard desktop computers or consumer motherboards.

DDR3L Platform Constraints

The memory operates at 1600 MT/s with CL11 latency and 1.35V voltage under the PC3L-12800 standard. Registered ECC modules cannot be mixed with unbuffered or load-reduced DIMMs in the same system. Compatibility is limited to platforms that explicitly support DDR3L registered ECC memory.

Build and Connector Details

The 240-pin DIMM uses a 2Rx4 organisation without a heat spreader, relying on server chassis airflow for cooling. JEDEC and RoHS compliance ensure the module meets industry specifications for reliable installation. Each unit is tested in-house before shipment to verify operation in the target Cisco systems.

Questions about this item

Should I choose this 16 GB module or add multiple units to reach a higher total?

Each module provides 16 GB of DDR3L 1600 ECC registered memory. Populate the Cisco UCS C24 M3, C240 M3 or C420 M3 with identical modules to reach the capacity your workload requires.

What does the PC3L-12800 rating deliver in a Cisco UCS server?

PC3L-12800 specifies a peak transfer rate of 12 800 MB/s at 1600 MHz with CL11 latency. The server’s memory controller will run the module at this speed when all slots are populated with matching registered DIMMs.

How does the 240-pin DDR3L registered interface limit my upgrade options?

The 240-pin DDR3L ECC registered form factor fits only DDR3L registered slots. It cannot be mixed with unbuffered or load-reduced DIMMs, and it will not work in standard desktop or consumer motherboards.
