16GB DDR3L ECC RDIMM

This 16GB DDR3L 1333 ECC Registered DIMM targets administrators upgrading select workstations, servers, NAS units or routers. The single 2Rx4 module delivers 16GB of capacity at PC3L-10600 speed with CL9 latency. It requires a platform that supports registered ECC memory and will not function in standard desktop systems.

240-pin JEDEC build

The module follows the 240-pin DDR3L form factor and operates at 1.35V, matching JEDEC and RoHS standards. No heat spreader is fitted, so clearance inside dense server chassis remains uncomplicated. Registered buffering and ECC circuitry add data-integrity protection for mission-critical workloads, but the stick cannot be mixed with unbuffered memory.

Low-voltage thermals

Running at 1.35V reduces power draw compared with standard DDR3, helping keep system thermals manageable in multi-DIMM configurations. The absence of a heat spreader means airflow across the PCB handles cooling directly, so adequate case ventilation is expected. Power consumption scales with the number of installed modules.

Questions about this item

What is the DDR3L 1333 speed rating and what bandwidth does PC3L-10600 provide?

This module runs at DDR3L 1333 MHz with a PC3L-10600 rating, delivering up to 10600 MB/s of theoretical bandwidth.

Does the 240-pin form factor fit standard server DIMM slots and what clearance does the lack of a heat spreader give?

Yes, the 240-pin DDR3L RDIMM fits standard server DIMM slots, and having no heat spreader keeps the module low-profile for tight chassis clearance.

How do I install this ECC registered RDIMM and what common mistake should I avoid?

Power down the system, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until the latches click, then verify the BIOS recognises the full 16 GB; the frequent error is mixing this registered DIMM with unbuffered memory, which the platform will not support.
