Two green DDR4 ECC SODIMM modules with gold contacts

OWC

OWC 64GB (2×32GB) DDR4 2666MHz ECC SODIMM for Synology RS822+/RS822RP+

SKU CH-08YS-KZTG2

Adds 64 GB of DDR4 2666 MHz ECC memory to Synology RS822+ and RS822RP+ NAS units in a two-module kit

  • Capacity64GB (2 x 32GB)
  • Type260-Pin DDR4 ECC SODIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes

Capacity 64GB (2 x 32GB)

  • 64GB total capacity with two 32GB modules for maximum Synology NAS memory
  • ECC error correction protects data integrity in RS822+ and RS822RP+ systems
  • DDR4 2666MHz CL19 speed with backward compatibility to 2400MHz and 2133MHz
  • JEDEC-standard 1.2V unbuffered SODIMM ensures warranty-safe upgrade compliance
  • 260-pin 2Rx8 configuration designed specifically for Synology RackStation compatibility

System-Specific Upgrade Kit

This 64 GB kit contains two 32 GB DDR4 ECC SODIMMs built for Synology RackStation RS822+ and RS822RP+ units. It targets administrators who need maximum supported memory for virtualization, container workloads or large file caches in these specific NAS models. Buyers whose systems use a different form factor or lack ECC support cannot use this kit.

260-Pin DDR4 Integration

Each module fits a standard 260-pin SODIMM slot and runs at 1.2 V without a heat spreader, leaving clearance for tight chassis airflow. The unbuffered, dual-rank design drops into the two available slots on the RS822 series, freeing no extra slots but delivering the full 64 GB capacity the platform accepts. JEDEC and RoHS compliance keeps the original system warranty intact.

Sustained 2666 MT/s Operation

Rated at PC4-21300 with CL19 latency, the modules maintain 2666 MT/s throughput under continuous NAS workloads such as deduplication, encryption or multi-user file serving. ECC corrects single-bit errors in real time, preventing silent data corruption during long uptime periods. Backward compatibility with 2400 MT/s and 2133 MT/s buses allows the kit to clock down automatically if the platform requires it.

Domande su questo articolo

Will the 2666 MHz speed hold steady under constant NAS workloads?

The modules run at DDR4 2666 (PC4-21300) with CL19 latency, and JEDEC compliance ensures stable operation at that speed during sustained use.

How much heat or power draw should I expect from these ECC SODIMMs running 24/7?

Each 32 GB stick operates at 1.2 V without a heat spreader, keeping power draw low and thermals manageable inside the RS822+ or RS822RP+ chassis.

Do I need any specific firmware version or BIOS setting on the Synology for this 64 GB kit to be recognised?

The kit is validated for Synology Rackstation RS822+ and RS822RP+; installation is a straightforward DIY upgrade with no extra firmware steps required.
