Server Memory Kit

This OWC kit supplies 32GB of DDR3L memory across four 8GB registered DIMMs. It is built for Cisco UCS C200 M2 and C210 M2 servers that require ECC registered modules. The kit will not work in standard desktop computers or alongside unbuffered or load-reduced memory.

Thermals and Power

Each module operates at 1.35V, the standard DDR3L voltage, which reduces power draw compared with 1.5V DDR3. No heat spreaders are fitted, so airflow through the server chassis handles cooling. Registered buffering adds minimal electrical load on the memory controller.

Sustained Load Behaviour

ECC registered operation corrects single-bit errors during continuous workloads, helping maintain data integrity in virtualisation or database tasks. CL11 latency at 1600MHz provides consistent timing for long-running server applications. The four-module population fills four slots for balanced channel utilisation.

Questions about this item

How do I install these 240-pin DDR3L ECC Registered RDIMMs in a Cisco UCS C200 M2 or C210 M2, and what step is often missed?

Power down the server, open the chassis, align each 240-pin module with the DDR3L slot key, press firmly until both retention clips lock, then verify in BIOS that all 32GB (4×8GB) are detected at 1600 MHz CL11; the step often missed is confirming the registered ECC mode is enabled.

What maintenance or replacement will this 32GB DDR3L 1600 kit need over its service life?

No routine maintenance is required; if a module fails, replace the faulty 8GB 2Rx4 RDIMM with an identical DDR3L 1600 CL11 1.35V registered ECC part to keep matched ranks across the four slots.

What limit appears first when these 1.35V DDR3L 1600 RDIMMs run sustained workloads in a Cisco UCS C200 M2 or C210 M2?

The memory controller’s maximum supported frequency of 1600 MHz and the registered buffer’s timing at CL11 set the throughput ceiling; thermal throttling is unlikely at the standard 1.35V operating voltage.
