  • Backward compatible with 2400 MHz and 2133 MHz systems

Synology DS1618+ memory upgrade

This 8 GB DDR4 ECC SODIMM is built specifically for the Synology DiskStation DS1618+ NAS. It delivers 2666 MHz speed with CL19 latency at 1.2 V in a 260-pin unbuffered form factor. The single-rank module adds capacity without requiring registered memory support.

DDR4 SODIMM speed limits

The module runs at PC4-21300 2666 MHz and is backward compatible with 2400 MHz and 2133 MHz systems. JEDEC compliance ensures stable operation within the DDR4 SODIMM standard. ECC functionality depends on the host platform supporting error-correcting code memory.

ECC unbuffered SODIMM requirement

This upgrade works only in systems that accept 260-pin DDR4 ECC unbuffered SODIMMs with 1Rx8 organisation. Buyers whose NAS or micro server requires registered DIMMs, non-ECC memory, or a different pin count cannot use this module.

Highlights

  • ECC protection safeguards data integrity in your NAS

  • 2 V operation reduces power draw and heat
  • 260-pin SODIMM form factor fits the memory slot
  • Backward compatible with 2400 MHz and 2133 MHz systems

Questions about this item

Should I buy one 8 GB module or add a second for dual-channel?

The DS1618+ has four slots; adding a second identical 8 GB stick enables dual-channel bandwidth, while a single module runs single-channel.

Will the CL19 2666 MHz rating actually run at that speed in my DS1618+?

The NAS officially supports 2666 MHz; the module will operate at its rated 2666 MHz CL19 without down-clocking.

Is the 260-pin SODIMM interface compatible with the DS1618+ memory slots?

Yes, the DS1618+ uses 260-pin DDR4 SODIMM slots, so this module fits directly without adapters.
