Server memory upgrade for Micron-compatible

This 16GB DDR3 module operates at 1066MHz with PC3-8500 bandwidth and CL7 latency. It uses registered ECC technology and a 4Rx4 organisation to provide error correction and signal buffering for server and workstation motherboards. The stick runs at the standard 1.5V DDR3 voltage.

Fits 240-pin DDR3 RDIMM slots in qualified systems

The registered design reduces electrical load on the memory controller, allowing higher module counts per channel than unbuffered alternatives. ECC circuitry detects and corrects single-bit errors to protect data integrity in continuous workloads. Verify your platform’s qualified vendor list before installation.

16GB capacity suits virtualisation

The single-module layout leaves additional DIMM slots free for future expansion within the platform’s maximum memory limit. Registered operation and 4Rx4 ranking optimise stability at high densities rather than low-latency desktop performance. Systems requiring faster DDR3 speeds or higher per-module capacity will need different specifications.

Questions about this item

What is the registered design's effect on the 16GB DDR3 1066MHz module's stability under continuous server workloads?

The registered architecture places a register between the DRAM chips and the memory controller, reducing electrical load per channel so the 16GB module maintains signal integrity during sustained 24/7 operation.

How much heat does the 1.5V DDR3 RDIMM produce when running at full 1066MHz speed all day?

At the standard 1.5V DDR3 voltage the 16GB module draws minimal power, generating low heat that typical server airflow handles without extra cooling.

Which motherboard slot and chipset support are required for this 240-pin ECC RDIMM to function?

A DDR3 240-pin registered DIMM slot with ECC support in the chipset is needed; the 4Rx4 organisation also requires a memory controller that can address four ranks per module.
