8GB DDR4 ECC module for Synology RS3617RPxs

This 8GB DDR4 2133MHz ECC unregistered DIMM is built for the Synology RackStation RS3617RPxs. It adds 8GB of error-correcting memory to support data integrity in always-on storage workloads. The module runs at 1.2V with CL15 timing and uses a 288-pin form factor. It is a single-stick upgrade for compatible NAS units.

Upgrade path from non-ECC or lower capacity

Replacing non-ECC memory with this ECC module enables error detection and correction for critical file services. The jump is worth it when the RS3617RPxs runs ZFS, virtual machines or databases that benefit from corrected single-bit errors. It also applies when the system currently has less than 8GB per slot and the workload demands more capacity per channel. Builders who need registered DIMMs or speeds above 2133MHz cannot use this module.

Fits 288-pin DDR4 slots in the RS3617RPxs

The stick plugs directly into the 288-pin DDR4 slots of the Synology RackStation RS3617RPxs without adapters. Its low-profile design without a heat spreader clears tight drive cages and airflow paths. The 1.2V operation matches the platform's standard voltage, leaving headroom for other components. Systems requiring 200-pin SoDIMM or registered memory are not compatible.
