ECC Registered DIMM Kit for Servers

This 16GB kit contains two 8GB DDR3L modules rated at 1066MHz with CL7 latency. Each stick is a 240-pin registered DIMM operating at 1.35V and includes ECC error correction. The modules use a 2Rx4 rank configuration and are designed as a dual-channel pair. They are built specifically for compatible workstations, servers, NAS systems or routers.

Thermals and Power at 1.35V

The DDR3L voltage of 1.35V reduces power draw compared with standard DDR3 modules running at 1.5V. No heat spreaders are fitted, so airflow across the bare PCB handles cooling in normal server chassis. Registered buffering adds a small electrical load but keeps signal integrity stable under sustained workloads.

Registered ECC Requirement

These modules only function in systems that support registered ECC DDR3L memory. They will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs. Verify that your platform explicitly lists DDR3L 1066 registered ECC support before purchasing.

Questions about this item

How do I install the 240-pin DDR3L ECC RDIMM modules in a dual-channel kit?

Power down the server, open the chassis, align each 240-pin module with the DIMM slot notch, press firmly until the retention clips lock, then populate matching channel slots per the system manual to enable dual-channel operation.

What maintenance or replacement will the 1.35V ECC Registered DIMMs need later?

No routine maintenance is required; if a module fails, replace it with an identical 8GB DDR3L 1066 CL7 2Rx4 registered DIMM to preserve ECC integrity and dual-channel balance.

What limit appears first when the 1066MHz CL7 registered memory runs under sustained load?

The DDR3L 1066 PC3L-8500 speed and CL7 latency set the throughput ceiling; sustained workloads will hit this bandwidth limit before voltage or thermal constraints become a factor.
