16 GB DDR4 ECC SODIMM for Synology DS923+

This 16 GB module adds ECC-protected DDR4 memory to the Synology DiskStation DS923+. It runs at 2666 MHz with CL19 latency and operates at 1.20 V. The unbuffered 260-pin SODIMM is built with major OEM chips and validated for that specific NAS.

Suited for DS923+ owners who need ECC reliability

Buyers with a different NAS, a laptop or a desktop that requires non-ECC memory should look elsewhere. Systems that only accept registered or load-reduced DIMMs cannot use this unbuffered stick. The single-rank 2Rx8 organisation also means it will not fill a quad-rank requirement.

The ECC unbuffered SODIMM form factor decides fit

Only platforms that explicitly support DDR4 ECC unbuffered SODIMMs at 2666 MHz can accept this part. The 260-pin keying and 1.20 V voltage are fixed by the module design. Verify the motherboard or NAS specification for ECC unbuffered support before purchasing.

Questions about this item

Does this 260-pin DDR4 SODIMM fit the memory slot on a Synology DS923+?

Yes, the module is a 260-pin DDR4 ECC SODIMM built for the DS923+ memory slot.

What is the correct way to seat this 1.2 V ECC module, and what step do people often miss?

Align the notch with the slot key, press firmly until both side clips click, then verify the system reports 16 GB at 2666 MT/s with ECC active.

Will the Samsung, Micron or Hynix chips on this 2Rx8 module need replacement under normal NAS workloads?

The chips are rated for continuous operation; no scheduled replacement is required unless a memory error is logged by the DSM operating system.
