OWC 32GB (2x16GB) DDR4 2666MHz ECC SODIMM for Synology DS1823+ DS2422+

SKU CH-8MRC-705F2

A 32 GB DDR4 2666 MHz ECC SODIMM kit with two 16 GB modules, CL19 latency and 1.2 V operation, validated for Synology DS1823+ and DS2422+ NAS units

Capacity 32GB (2 x 16GB)

  • 32 GB kit expands NAS capacity for heavier workloads
  • Dual 16 GB modules populate both slots for balanced bandwidth
  • DDR4 2666 MHz CL19 meets Synology DS1823+ and DS2422+ specs

32 GB DDR4 ECC kit for Synology NAS

This OWC kit provides 32 GB of DDR4 2666 ECC memory in two 16 GB SODIMM modules. It is validated for Synology DiskStation DS1823+ and DS2422+ systems. The unbuffered ECC design adds data integrity for always-on storage workloads. Buyers needing non-ECC modules or higher speeds should look elsewhere.

JEDEC-standard 260-pin SODIMM build

Each module follows the PC4-21300 CL19 1.2 V specification with a 2Rx8 organisation and no heat spreader. The 260-pin form factor fits the factory SO-DIMM slots on the target NAS units. JEDEC and RoHS compliance ensures a warranty-safe upgrade without proprietary deviations. Installers requiring registered DIMMs or taller heatsinks cannot use this kit.

Replaces factory 2133 or 2400 MHz memory

The modules are backward compatible with 2133 MHz and 2400 MHz configurations, so they upgrade existing capacity while retaining stability. The jump is worth it when virtual machines, Docker containers or large file caches exceed the stock memory limit. Systems already running at the maximum supported capacity will not benefit.

商品問答

Does the DDR4 2666 PC4-21300 interface cap speed at 2666MHz even if the Synology NAS supports faster memory?

The modules run at DDR4 2666 PC4-21300 CL19 and will not exceed 2666MHz; they are also backward compatible with 2400MHz and 2133MHz bus speeds.

Will the 260-pin SODIMM form factor fit the memory slots in a DS1823+ or DS2422+ without a heat spreader?

Yes, the 260-pin DDR4 ECC SODIMM has no heat spreader and matches the slot layout used in the DS1823+ and DS2422+.

What is the correct installation sequence for the two 16GB sticks, and which step do people often miss?

Power off the NAS, unplug it, open the chassis, insert both 16GB modules firmly until the side clips click, then reassemble; the step often missed is fully seating each stick so both clips engage.
