16GB DDR3L ECC Registered DIMM

This 16GB DDR3L 1600 module uses 2Rx4 organisation and runs at 1.35V with CL11 latency. It is built for workstations, servers, NAS systems and routers that require ECC registered memory. The 240-pin form factor fits compatible Supermicro X9DAL, X9DAX, X9DB3, X9DBi and X9DBL motherboards.

ECC registered operation

Error-correcting code and registered buffering improve data integrity and signal stability in multi-module configurations. These features change how the memory controller manages each rank, so the module cannot be mixed with unbuffered or non-ECC DIMMs. The single 16GB stick adds capacity without altering the registered topology.

Platform and population rules

Verify that your motherboard is one of the listed Supermicro X9 series models and that the BIOS supports registered ECC DDR3L at 1600 MT/s. Confirm the available DIMM slots match the 240-pin layout and that you are not combining this stick with unbuffered memory. Check the system documentation for maximum per-slot and total capacity limits before ordering.

Questions about this item

Does the 2Rx4 240-pin DDR3L module require any periodic maintenance or replacement?

No, the 16GB DDR3L 1600 CL11 2Rx4 240-pin 1.35V ECC RDIMM has no moving parts and needs no scheduled maintenance or replacement.

What limit appears first when the registered ECC RDIMM runs at 1600MHz continuously?

The CL11 latency at 1600MHz sets the timing boundary that governs sustained throughput on this 1.35V DDR3L module.

How much heat or fan noise does the 1.35V 16GB DDR3L RDIMM produce under all-day load?

The low 1.35V DDR3L voltage keeps heat output minimal, and with no heat spreader or fan the module adds no audible noise.
