System-specific DDR4 ECC SODIMM for Synology DS1522+

This 8 GB module is built for the Synology DiskStation DS1522+ and carries a 260-pin DDR4 ECC unbuffered design. It runs at 2666 MHz with CL19 latency and 1.2 V operation. The single-rank 1Rx8 layout matches the platform's memory controller requirements. Buyers needing non-ECC or registered DIMMs cannot use this part.

Sustained-load behaviour in a NAS enclosure

ECC circuitry detects and corrects single-bit errors during continuous file-serving, backup and virtualization workloads. JEDEC-standard signalling and 1.2 V power keep thermals steady inside the compact chassis. Backward compatibility with 2400 MHz and 2133 MHz buses allows the module to clock down automatically if the system demands it. No heat spreader is fitted, so airflow across the slots remains the only cooling path.

Capacity and form factor decide fit

The upgrade adds exactly 8 GB per slot in the 260-pin SODIMM form factor. Verify the DS1522+ slot count and maximum supported capacity before purchase. Systems that require registered memory or a different pin count will not accept this module.

이 상품에 대한 질문

How much heat and power does the 1.2V DDR4 2666MHz module draw during continuous NAS operation?

The module runs at the standard DDR4 1.2V with no heat spreader, so power draw and heat output stay low during all-day use in the DS1522+.

What must the Synology DS1522+ already have for this 260-pin ECC SODIMM to work?

The DS1522+ needs an available DDR4 SODIMM slot that accepts 260-pin ECC unbuffered memory; the system ships with such slots ready for this upgrade.

Will the CL19 2666MHz stick run correctly alongside existing 2400MHz or 2133MHz modules in the same NAS?

Yes, the module is backward compatible with 2400MHz and 2133MHz speeds, so it will downclock automatically to match slower sticks already installed.
