Compatible DDR4 ECC SODIMM for Synology DS2422+

This 16 GB DDR4 2666 module is built as a direct upgrade for the Synology RackStation DS2422+. It uses 260-pin SODIMM form factor, ECC unbuffered operation and 1.2 V voltage to match the NAS memory slots. The stick is validated for that single platform.

Suitable for DS2422+ owners needing ECC

Buyers with a Synology DS2422+ can add this module to increase memory capacity. It will not work in systems that require registered DIMMs, non-ECC SODIMMs, DDR5 speeds or 288-pin desktop slots.

2Rx8 dual-rank organisation

The module uses a 2Rx8 rank layout, which the DS2422+ memory controller expects for full compatibility. Single-rank or 2Rx16 alternatives may not be recognised by this NAS.

Questions about this item

Does the 16GB DDR4 2666 ECC SODIMM arrive as a single stick or a kit?

The module is supplied as one 16GB stick (1X16GB) in a 260-pin SODIMM form factor.

Should I pick the 2Rx8 CL19 version or a different rank and latency for my DS2422+?

The 2Rx8 CL19 1.2V configuration matches the Synology DS2422+ qualified specification.

Will the PC4-21300 rating run at 2666 MT/s once installed in the NAS?

Yes, the PC4-21300 designation corresponds to DDR4 2666 operation at 1.2V in the DS2422+.
