Speed DDR4 2666 (PC4 21300)

  • 4GB DDR4 2666MHz boosts NAS responsiveness
  • 260-pin SODIMM fits Synology 18, 19 and 20 series bays
  • Non-ECC unbuffered design matches Synology D4NESO-2666-4G spec
  • 2V CL19 single-rank 512x8 chips keep power draw low
  • Lifetime warranty and US-based tech support included

Capacity and fit

This 4 GB DDR4 SODIMM is built for Synology 18, 19 and 20 series NAS units. It replaces the D4NESO-2666-4G module in models such as the DS1618+, DS1819+, DS2419+II and DS920+. Buyers running a compatible 20-series, 19-series or 18-series system can install it directly.

DDR4 2666 practical limits

The module runs at 2666 MHz PC4-21300 with CL19 timing at 1.2 V. That speed ceiling is set by the memory controller in the supported Synology platforms. Adding more modules will not raise the frequency beyond 2666 MHz, and the single-rank 260-pin layout cannot be mixed with ECC or registered DIMMs.

Upgrade context

This kit upgrades a Synology NAS that shipped with less memory or a slower SODIMM. The jump is worth it when the unit handles multiple Docker containers, virtual machines or heavy file indexing and the current RAM is a bottleneck. It is not for systems outside the listed 18, 19 and 20 series or for boards that require ECC or registered memory.

Questions sur cet article

Should I pick the 4GB module or a larger capacity for my DS920+?

This listing only offers a single 4GB SODIMM; choose it if your NAS has a free slot and you want to add 4GB of DDR4 2666 memory.

What does the 2666MHz rating deliver inside a Synology DS720+?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency, giving the NAS its rated memory bandwidth for file serving and virtualization tasks.

Will the 260-pin DDR4 SODIMM interface work in my RS820RP+ without speed limits?

Yes — the 260-pin DDR4 SODIMM fits the RS820RP+ memory slot and operates at the full 2666MHz speed supported by the platform.
