Synology DS1823xs+ 8 GB DDR4 ECC SODIMM

This 260-pin DDR4 ECC SODIMM adds 8 GB of error-correcting memory to the Synology RackStation DS1823xs+. The unbuffered module runs at 2666 MHz with CL19 timing and 1.20 V operation. It is built for IT professionals who need reliable capacity expansion in a validated NAS platform.

Thermals and power in normal NAS workloads

The module has no heat spreader and draws 1.20 V at stock speed, keeping power draw low inside the chassis. Passive cooling from system airflow is sufficient for typical file-serving and backup tasks. Acoustic impact is negligible because the stick adds no active cooling components.

What the validated compatibility changes

Each stick is stress-tested under load for the DS1823xs+ so the NAS recognises the module at POST without manual configuration. The ECC function corrects single-bit errors automatically, protecting data integrity during RAID rebuilds and long uptime periods. The single 1Rx8 rank layout matches the system's memory controller expectations.

Perguntas sobre este artigo

How do I install this 260-pin SODIMM in my Synology DS1823xs+ and what step is often missed?

Power off the NAS, remove the cover, insert the module at an angle into the slot until the gold contacts are hidden, then press down firmly until the side clips click; the step often missed is fully seating the module so both clips engage.

What maintenance or replacement will this ECC DDR4 module need later?

No routine maintenance is required; if a memory error appears in DSM logs, replace the module, otherwise it runs for the life of the system.

What limit appears first under sustained heavy workloads on this CL19 1.20V module?

The CAS latency of CL19 sets the access timing ceiling; sustained loads hit that timing limit before voltage or thermal throttling becomes a factor.
