OWC 32GB (2x16GB) DDR4 2666MHz CL19 ECC SODIMM for Synology DS1823XS+

SKU CH-H2V2-N3APN

ECC SODIMM kit adds 32 GB of DDR4-2666 CL19 memory to the Synology DS1823XS+ NAS

  • Total capacity32 GB (2 × 16 GB)
  • Rated speedDDR4 2666 (PC4 21300)
  • CAS latencyCL19
  • Rated voltage1.2 V
  • Buffer typeUnbuffered

Capacity 32GB (2 x 16GB)

  • 32 GB kit expands NAS capacity for heavier workloads
  • Dual 16 GB modules populate two slots for balanced throughput
  • DDR4 2666 CL19 ECC protects data integrity in Synology DS1823XS+

Synology DS1823XS+ 32GB ECC kit

This two-module kit adds 32GB of DDR4 ECC memory to the Synology DS1823XS+ NAS. Each 16GB SODIMM runs at 2666MHz with CL19 timing at 1.2V. The unbuffered 2Rx8 design meets JEDEC and RoHS standards for a warranty-safe upgrade. Installation is a straightforward DIY task for most owners.

Ideal for NAS workloads needing ECC

The kit suits administrators who want error-correcting memory for data integrity on the DS1823XS+. It will not fit systems that require registered or load-reduced DIMMs, nor platforms limited to non-ECC SODIMMs. Buyers needing more than 32GB total capacity must look for higher-density modules. Systems using a different DDR generation or pin count are incompatible.

260-pin DDR4 SODIMM form factor

The decisive specification is the 260-pin DDR4 SODIMM form factor combined with ECC unbuffered operation. Only platforms accepting this exact module type can use the kit. The DS1823XS+ is the validated target; other hardware must confirm 260-pin DDR4 ECC SODIMM support before purchase.

Questions about this item

Should I choose the 32GB kit or a smaller capacity for my DS1823XS+?

The DS1823XS+ supports up to 32GB across its two SODIMM slots, so this 2×16GB kit fills both sockets and reaches the platform maximum.

What does the 2666MHz rating mean once installed in the DS1823XS+?

The system memory controller runs at 2666MT/s; the modules operate at that speed with CL19 latency and 1.2V.

Is the 260-pin DDR4 SODIMM interface limited by the NAS platform?

The DS1823XS+ memory controller caps at DDR4 2666, so the modules run at their rated 2666MHz rather than a lower speed.
