  • Single-rank 1Rx8 layout with CL19 timing ensures stable unbuffered performance

Synology DDR4 2666 ECC SODIMM

This 8 GB DDR4 2666 ECC SODIMM module targets Synology NAS owners and workstation users who need error-correcting memory for data integrity. It arrives as a single 260-pin stick rated at PC4-21300 with CL19 latency and 1.20 V operation.

Fits 260-pin DDR4 SODIMM slots

The module plugs directly into compatible Synology systems that accept unbuffered ECC DDR4 SODIMMs. Its 1Rx8 organisation and Samsung-compatible chipset let you add capacity without proprietary locking, freeing the board's remaining slots for further expansion.

Runs at 1.20 V without a heat spreader

Standard voltage keeps power draw low in the tight confines of a NAS chassis. The bare PCB relies on system airflow for cooling, so ensure the enclosure provides adequate circulation; acoustic impact is negligible because the module has no moving parts.

Questions about this item

Does the CL19 latency limit throughput when the NAS runs sustained workloads?

CL19 is the rated CAS latency at 2666 MT/s; sustained throughput is governed by the memory controller and the workload, not by the latency figure alone.

How much power does the module draw during continuous operation?

The module operates at 1.20 V; actual power draw depends on the system's memory controller and activity level.

What must the system provide for this SODIMM to function?

A DDR4 SODIMM slot that accepts 260-pin unbuffered ECC modules at 1.20 V.
