16GB Memory 1600DDR3L-8GBx2 Replacement for Synology NAS - Reliable

In this review the reviewer looks at the 16GB Memory1600DDR3L-8GBx2 replacement kit designed for Synology DiskStation systems, especially the DS1817+. The bottom line: this kit is for users who need a straightforward, compatible RAM upgrade to speed up multitasking and data access on their NAS. It is most appealing because it matches Synology memory specifications exactly and runs at a low 1.35 volt profile, so it avoids power or compatibility surprises while offering a tangible performance uplift for caching and concurrent access.

Key Features

• Capacity: Two 8GB modules provide a combined 16GB of memory to improve multitasking and file serving on the NAS.
• Speed: DDR3L-1600 (PC3L-12800) operation delivers consistent 1600MHz bandwidth for smoother data access under load.
• Voltage: The 1.35 volt low-voltage design helps reduce power draw and heat compared with standard 1.5V modules in compact NAS enclosures.
• Timing: CAS Latency 11 offers a predictable latency profile that matches Synology memory expectations for stable operation.
• Compatibility: Sold as compatible with Synology RAM1600DDR3L-8GBx2 and intended for models like the DiskStation DS1817+, minimizing installation hassles.
• Warranty: Lifetime replacement warranty included gives long-term peace of mind for use in always-on NAS hardware.

Who It's For

This kit is aimed at home and small-business NAS owners who run Synology DiskStation models and need more memory for heavier I/O, virtual machine hosts, or multi-user file services. Someone upgrading from 4GB or 8GB will notice improved responsiveness for indexing, backups, and simultaneous user access.

It is less relevant for users whose NAS model does not accept 204-pin DDR3L SODIMM modules or for those who require ECC registered memory; enterprise SAN appliances that demand server-grade ECC should look elsewhere. Casual users with minimal concurrent activity may not need the full 16GB.

Pros & Cons

Pros

• Direct compatibility with Synology DDR3L-1600 specifications makes installation straightforward for supported DiskStation models.
• Low 1.35V operation reduces power consumption and heat inside compact NAS enclosures.
• Lifetime replacement warranty provides a safety net for long-term use in always-on systems.
• Dual-module 8GBx2 configuration enables full 16GB capacity for improved multitasking and caching.

Cons

• Not suitable for systems that require ECC registered memory or different SODIMM pin counts.
• CAS Latency 11 is standard for this class but not tuned for ultra-low latency applications.
