Synology DS2422+ 8 GB ECC SODIMM

This 8 GB DDR4 2666 ECC SODIMM is built for the Synology RackStation DS2422+ NAS. It adds error-correcting memory to a single slot, helping the system maintain data integrity during heavy file serving or virtualization workloads. The module is unbuffered and runs at 1.20 V.

DDR4 2666 speed and CL19 latency

The DDR4 2666 interface caps transfer rates at PC4-21300 bandwidth with a CAS latency of 19. ECC operation adds a parity check cycle, so raw throughput is slightly lower than non-ECC equivalents at the same clock. The 260-pin form factor fits only DDR4 SODIMM slots.

Upgrade from non-ECC or lower capacity

Replacing a non-ECC module removes silent data corruption risk for ZFS or Btrfs volumes. Moving from 4 GB to 8 GB per slot doubles the addressable memory for Docker containers or VMs. The jump is worth it when the NAS runs multiple services or hosts large deduplication tables.

Questions about this item

Should I buy one 8 GB module or fill multiple slots for the Synology DS2422+?

Each module is a single 8 GB stick; add as many as the NAS slots allow to reach your desired total capacity.

What does the 2666 MHz rating deliver inside the DS2422+?

The memory runs at DDR4 2666 (PC4-21300) with CL19 latency, providing ECC error correction for data integrity in the NAS.

Will the 260-pin DDR4 SODIMM fit and work at the rated speed?

Yes, it is a 260-pin DDR4 ECC unbuffered SODIMM at 1.2 V, matching the DS2422+ memory slot and voltage requirements.
