Synology NAS ECC memory kit

This 16 GB kit contains two 8 GB DDR3 1600 ECC unbuffered DIMMs built for Synology NAS models DS3615xs, RS3614RPxs, RS3614xs and RS3617xs. It targets administrators who need error-correcting memory for data-integrity workloads on those specific units.

240-pin DDR3 1.5 V modules

Each stick is a 240-pin UDIMM rated at PC3-12800 CL11 and operates at the standard 1.5 V. The kit plugs directly into the compatible NAS slots without registration or buffering, freeing the system to use all available DIMM positions for the full 16 GB capacity.

Replaces Synology RAMEC1600DDR3-8GBX2

The kit serves as a direct substitute for the OEM part number listed above, matching JEDEC and RoHS specifications. The upgrade is worthwhile when the NAS currently runs with less memory or non-ECC modules and the workload demands the extra capacity and error correction these DIMMs provide.

Questions about this item

What is the CAS latency of these DDR3 1600 modules?

The CAS latency is CL11, matching the PC3-12800 specification for this kit.

How much heat do the unbuffered ECC DIMMs generate during continuous NAS operation?

The modules run at 1.5 V with no heat spreader, so they rely on chassis airflow to stay cool under sustained load.

Which Synology NAS models must I already own for this 240-pin kit to be compatible?

This kit is validated for the DS3615xs, RS3614RPxs, RS3614xs and RS3617xs.
