OWC

OWC 8GB DDR4 2666 ECC SODIMM for DS1823+ DS2422+ memory upgrade

SKU CH-SP2Q-V5D95

An 8 GB DDR4 ECC SODIMM running at 2666 MHz with CL19 latency, validated for Synology DS1823+ and DS2422+ NAS units

  • Total capacity8 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • CAS latencyCL19
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Memory rank1Rx8

Capacity 8GB

  • 8GB DDR4 ECC SODIMM boosts NAS multitasking capacity
  • 2666MHz CL19 speed matches Synology DS1823+ and DS2422+ specs
  • JEDEC and RoHS compliant for warranty-safe upgrades
  • 2V low-voltage operation reduces power draw and heat
  • Backward compatible with 2400MHz and 2133MHz systems

Targeted NAS Memory Upgrade

This OWC module adds 8GB of DDR4 2666 ECC SODIMM memory to Synology DiskStation DS1823+ and DS2422+ units. It runs at 1.2V with CL19 latency and uses a 260-pin unbuffered 1Rx8 design. The part is validated for those specific models and meets JEDEC and RoHS standards for a warranty-safe installation.

Not for Other Systems

Builders working on desktops, laptops, or non-listed NAS devices cannot use this SODIMM because the firmware and form factor are tailored to the two Synology models. Buyers who need non-ECC memory, registered DIMMs, higher capacities per slot, or different pin counts should look at other product lines that match their hardware requirements.

260-Pin DDR4 ECC SODIMM Fit

The single specification that decides compatibility is the 260-pin DDR4 ECC SODIMM interface combined with the validated system list. Only Synology DiskStation DS1823+ and DS2422+ units are confirmed; any other platform requires separate verification before purchase.

Questions about this item

Will this 8 GB DDR4 2666 ECC SODIMM need any maintenance or replacement after installation?

No scheduled maintenance is required; the module is designed to last the life of the DS1823+ or DS2422+ and carries a limited lifetime warranty.

What limit appears first when the module runs continuously in a DS1823+ or DS2422+?

The memory controller caps operation at 2666 MT/s CL19, so bandwidth and latency are fixed at that JEDEC ceiling.

How much heat and power does the 1.2 V unbuffered ECC SODIMM produce during all-day NAS operation?

It draws 1.2 V without a heat spreader, so thermal output is low and fits the standard SODIMM slot cooling in both Synology models.
