OWC 16GB DDR4 2666MHz ECC SODIMM

This OWC module provides 16GB of DDR4 memory at 2666MHz with CL19 latency. It operates at 1.2V and uses a 260-pin SODIMM form factor with ECC error correction. The unbuffered design targets compatible micro servers, NAS systems, and POS terminals requiring data integrity.

Suitable for Synology DS723+ and DS923+ upgrades

Buyers expanding memory in a Synology DiskStation DS723+ or DS923+ NAS will find this module validated for those platforms. Systems needing registered or buffered DIMMs, non-ECC memory, or capacities beyond a single 16GB stick should look at other options.

ECC unbuffered SODIMM decides fit

The single specification that determines compatibility is the ECC unbuffered SODIMM designation at 2666MHz CL19. Your motherboard or NAS must explicitly support DDR4 ECC unbuffered SO-DIMMs to use this module.

Points forts

  • 16 GB single module expands NAS memory capacity
  • DDR4 2666 MHz CL19 delivers responsive multitasking performance
  • ECC unbuffered design protects data integrity in micro servers
  • 2 V low-voltage operation reduces system power draw
  • JEDEC and RoHS compliant for warranty-safe upgrades

Questions sur cet article

Will the ECC SODIMM need periodic replacement like a battery?

No, the 16 GB DDR4 module has no moving parts or consumable cells; it runs at 1.2 V and requires no scheduled replacement under normal use.

What limits sustained throughput first, the CL19 latency or the 2666 MT/s bus?

The 2666 MT/s PC4-21300 bus caps peak bandwidth; CL19 adds fixed cycle delay but does not throttle continuous transfer rates.

How much heat and power does the unbuffered 2Rx8 stick produce in a NAS running 24/7?

At 1.2 V the module draws only a few watts and has no heat spreader, so it adds minimal warmth inside a DS723+ or DS923+ chassis.
