Synology NAS Memory Upgrade

This 4 GB DDR4 SODIMM is built for Synology DiskStation units that require PC4-17000 modules. It targets administrators who need to expand capacity in a supported NAS without changing voltage or form factor.

2133 MHz CL15 Unbuffered Module

The stick runs at 2133 MHz with CL15 latency and 1.20 V operation in a 260-pin unbuffered layout. Major OEM chips from Samsung Micron or Hynix provide the specified timing. Systems that demand a different speed or voltage will not accept this part.

Sustained Load Stability

Every module undergoes extended stress testing under load before shipment. The validation process targets the continuous workloads typical of NAS environments rather than brief benchmark bursts. This reduces the chance of errors during long file transfers or RAID rebuilds.

Highlights

  • 4GB capacity expands NAS multitasking headroom
  • DDR4 2133 speed matches Synology spec
  • CL15 latency keeps response tight
  • 20V operation reduces power draw
  • 260-pin SODIMM fits DiskStation slots

Questions about this item

How does 2133 MHz DDR4 speed affect everyday NAS responsiveness?

The 2133 MHz DDR4 modules run at the native bus speed supported by compatible Synology DiskStation models, so file transfers and multitasking operate at the platform's rated throughput without downclocking.

What does the PC4-17000 rating tell me about bandwidth limits?

PC4-17000 certifies a peak transfer rate of 17 GB/s per module; the NAS memory controller caps actual throughput at that ceiling, so adding faster memory would not increase bandwidth.

Will the 260-pin SODIMM fit my Synology DiskStation memory slot?

Yes, the 260-pin DDR4 SODIMM form factor matches the SO-DIMM slots used in the compatible Synology DiskStation models listed for this upgrade.
