System-Specific DDR4 ECC SODIMM

This OWC kit supplies 16GB of DDR4 2666 memory in two 8GB modules built to the 260-pin SODIMM form factor. Each stick runs at 1.2V with CL19 latency and includes ECC error correction in an unbuffered 1Rx8 configuration. The set is validated for the Synology DiskStation RS1522+ and meets JEDEC PC4-21300 standards.

Synology RS1522+ owners adding capacity

The modules suit administrators who need to expand the RS1522+ beyond its stock memory for virtual machines, container workloads or large file caches. Buyers whose NAS uses a different slot type, requires registered DIMMs, or operates on a platform that cannot accept ECC unbuffered SODIMMs should look elsewhere.

ECC unbuffered 260-pin SODIMM

The defining specification is the combination of ECC unbuffered operation and the 260-pin SODIMM interface, which together determine whether the kit fits the target chassis and memory controller. Systems that demand registered ECC, non-ECC modules, or a different pin count will not accept these sticks.

商品問答

Should I choose the 16GB kit or add a single 8GB module to my RS1522+?

The kit provides two matched 8GB modules for 16GB total, enabling dual-channel operation in the RS1522+ for maximum throughput.

What does the 2666MHz CL19 rating deliver inside a Synology RS1522+?

At 2666MHz with CL19 latency the modules run at the RS1522+ native memory speed, giving low-latency ECC bandwidth for file services and virtualization.

How does the PC4-21300 DDR4 260-pin interface limit performance in this NAS?

The 260-pin DDR4 SODIMM slot in the RS1522+ accepts PC4-21300 modules; speed is capped at 2666MHz and the system will down-clock to 2400MHz or 2133MHz if required.
