Server-ready ECC RDIMM

This 8 GB DDR3 module is built for servers and workstations that require registered, error-correcting memory. It operates at 1866 MHz with a CL13 latency and standard 1.5 V supply. The single-rank 1Rx4 organisation uses Micron chips on a 240-pin DIMM.

Registered buffer and ECC

The registered design adds a clock-cycle delay to stabilise heavy memory loads across multiple modules. ECC circuitry detects and corrects single-bit errors, preventing data corruption in always-on environments. Systems that expect unbuffered non-ECC DIMMs will not accept this module.

8 GB capacity for typical workloads

One module delivers 8 GB of addressable space, suited to virtualisation hosts, database nodes or compute clusters running moderate datasets. Workloads that exceed this per-slot limit — such as large in-memory analytics or dense container fleets — will need higher-density RDIMMs or additional populated slots.

Questions about this item

What does the 1866MHz speed mean for my server workload?

The DDR3 1866MHz rating (PC3-14900) sets the maximum data rate the module can sustain when the memory controller runs at that frequency. Actual throughput depends on your platform's supported memory speed and the number of populated slots.

How does the registered ECC interface affect compatibility?

This module uses a registered (RDIMM) DDR3 interface with ECC. It requires a server or workstation chipset that supports registered ECC DIMMs; standard desktop boards will not accept it.

Will the 240-pin DIMM fit my motherboard slots?

The module is a standard 240-pin DDR3 DIMM. It fits DDR3 RDIMM slots keyed for registered memory; verify your system manual lists DDR3 1866MHz registered ECC support before installing.
