Synology RS1522+ 32GB DDR4 ECC kit

This 32GB kit contains two 16GB DDR4 2666 ECC SODIMM modules built for the Synology DiskStation RS1522+. Each stick runs at PC4-21300 with CL19 timing at 1.2V and uses a 2Rx8 unbuffered layout. The 260-pin form factor fits the NAS memory slots directly.

JEDEC and RoHS compliance for warranty-safe

The modules meet JEDEC standards and RoHS requirements, so the upgrade keeps the original system warranty intact. Backward compatibility with 2400MHz and 2133MHz buses allows the kit to run in older slots without configuration changes. No heat spreader is included, matching the factory design.

32GB total capacity for multi-user NAS workloads

The 32GB pool handles simultaneous file shares, Docker containers and virtual machines on the RS1522+ without paging. ECC protection corrects single-bit errors that can corrupt data in always-on storage. Workloads that exceed 32GB will still require a higher-capacity platform.

Perguntas sobre este artigo

Will the ECC SODIMMs need any periodic replacement or firmware updates in the Synology RS1522+?

No, the DDR4 ECC modules are passive components with no firmware. They are designed to remain in place for the lifetime of the NAS unless a capacity upgrade is desired.

What is the first limit reached when the RS1522+ runs memory-intensive workloads continuously?

The CL19 latency at 2666 MT/s sets the bandwidth ceiling. If the workload exceeds the 32 GB capacity, the system will swap to disk, which is the practical performance limit.

How much heat and power do the two 16 GB sticks add when the NAS operates 24/7?

Each module runs at 1.2 V without a heat spreader. The JEDEC-standard DDR4 design keeps thermal output low enough for the RS1522+ standard cooling.
