4 GB DDR4 SODIMM for Synology NAS

This module is a 4 GB DDR4 SODIMM rated at 2400 MT/s with CL17 latency. It uses a 260-pin unbuffered non-ECC layout at 1.20 V and is validated for Synology DiskStation systems.

Suitable for Synology owners adding capacity

It suits administrators who need a single 4 GB stick to expand a compatible Synology NAS. Builders requiring ECC protection, registered modules, higher capacities per slot, or speeds beyond 2400 MT/s should look elsewhere.

Speed grade 2400 MT/s (PC4-19200)

The decisive specification is the 2400 MT/s DDR4 rating matched to PC4-19200 bandwidth. Confirm the target NAS accepts this speed and a non-ECC 260-pin SODIMM before purchase.

Highlights

Questions about this item

Does this 260-pin SODIMM fit the memory slot on my Synology DiskStation?

Yes, the module uses the standard 260-pin DDR4 SODIMM form factor used by compatible Synology NAS units.

What is the correct orientation for inserting the module, and which notch alignment do people miss?

Align the off-centre notch on the gold edge connector with the key in the slot, press firmly until the side clips click into place.

Will I need to replace this memory if I upgrade to a newer Synology model that requires faster speeds?

The module runs at 2400 MT/s with CL17 latency; a future system needing 2666 MT/s would require faster memory.
