Server-grade DDR3 ECC RDIMM

This 16 GB DDR3-1600 registered DIMM is built for workstations, servers and compatible NAS appliances that require ECC error correction. It operates at 1.5 V with CL11 latency and a 2Rx4 organisation across 240 pins.

Sustained-load behaviour

ECC circuitry detects and corrects single-bit errors in real time, preventing data corruption during long compute runs or continuous file-serving workloads. Registered buffering reduces electrical load on the memory controller, helping stability when multiple modules populate a channel.

Compatibility checklist

Verify that your platform explicitly supports DDR3 ECC registered memory; standard desktop boards and unbuffered-only systems will not accept this module. Confirm the motherboard or NAS vendor lists 16 GB RDIMMs at 1600 MT/s and 1.5 V operation. Do not mix with unbuffered DIMMs.

Questions about this item

How much power does the 1.5V DDR3 1600 module draw when the server runs continuously?

The module operates at the standard 1.5V DDR3 voltage; actual power draw depends on your platform's memory controller and workload, so consult the system manual for precise figures.

What must my motherboard provide to use this 240-pin ECC Registered RDIMM?

A DDR3 240-pin slot that supports registered ECC memory; the board must accept 2Rx4 modules at PC3-12800 speed and run at 1.5V.

Can I add this 16GB stick alongside the 8GB unbuffered DIMMs already in my NAS?

No — registered ECC RDIMMs cannot be mixed with unbuffered memory; all slots must use registered ECC modules of matching specification.
