OWC DDR3L ECC Registered Kit

This 16GB kit contains two 8GB DDR3L 1600 registered DIMMs built for Dell PowerEdge servers including the R815, R820, T320, T420 and T620. It delivers ECC error correction and registered buffering required by those platforms. Standard desktop boards cannot use this memory and it must not be mixed with unbuffered modules.

Low Voltage Server Operation

The modules run at 1.35V, reducing power draw and heat output compared with standard DDR3. No heat spreaders are fitted, so airflow through the server chassis handles cooling silently. CL11 latency at 1600MHz provides stable throughput for virtualization and database workloads.

240-Pin RDIMM Form Factor

Each stick uses the 240-pin RDIMM layout keyed for registered server slots. The 1Rx4 rank organization matches the supported configurations for the listed Dell systems. Buyers needing unbuffered memory or higher capacities per module should look elsewhere.

Questions about this item

How do I install the 240-pin DDR3L RDIMMs in my Dell PowerEdge T620, and what step is often missed?

Power down, open the chassis, align each module's notch with the slot key, press firmly until the ejector tabs click, then verify in BIOS that all 16GB are recognised at 1600 MHz CL11.

What maintenance or replacement will this 16GB ECC registered kit need over time?

No routine maintenance is required; if a module fails, replace it with an identical 8GB 1Rx4 DDR3L 1600 CL11 1.35V registered DIMM to keep ECC protection intact.

What limit appears first when the memory runs under sustained load in a PowerEdge R820?

The CL11 latency at 1600 MHz and 1.35V voltage set the performance ceiling; sustained throughput cannot exceed the PC3L-12800 rating of the modules.
