32 GB DDR3L LRDIMM for Cisco UCS servers

This 32 GB DDR3L 1600 CL11 load-reduced ECC module is built for Cisco UCS C24 M3, C240 M3 and C420 M3 platforms. It targets administrators who need to expand memory capacity in those specific workstations and servers without changing the existing memory architecture.

Verify LRDIMM-only slots

The module uses a 4Rx4 organisation and 1.35 V operation, so the system must accept load-reduced DIMMs and cannot mix them with unbuffered or registered ECC memory. Confirm that all populated slots will use identical capacity, speed and rank layout before installation.

Steady throughput under continuous server workloads

JEDEC-compliant DDR3L signalling and ECC error correction maintain data integrity during prolonged compute tasks. The load-reduced design reduces electrical load on the memory bus, allowing sustained bandwidth at the rated 1600 MT/s speed without the signal degradation that can appear in dense configurations.

Questions about this item

What comes in the box and do I need to buy anything else?

The box contains a single 32 GB DDR3L 1600 CL11 4Rx4 240-pin 1.35 V ECC LRDIMM module. No extra parts or accessories are required for installation in a compatible Cisco UCS server.

How do I choose between the available versions or capacities of this OWC module?

This listing is for a single 32 GB DDR3L 1600 CL11 4Rx4 240-pin 1.35 V ECC LRDIMM. OWC recommends populating all slots with identical capacity, speed and manufacturer modules for optimal performance.

What does the DDR3L 1600 rating mean once the module is installed in a Cisco UCS C24 M3, C240 M3 or C420 M3?

The module operates at 1600 MT/s with CL11 latency at 1.35 V, providing ECC error correction and load-reduced signalling to maximise registered DIMM capacity in the supported Cisco UCS platforms.
