Synology DDR4-2666 So-DIMM 4GB

This Synology DDR4-2666 non-ECC So-DIMM delivers 4 GB of laptop memory for compatible systems. It is built for owners of supported Synology devices who need a straightforward capacity increase. The module uses standard DDR4 technology at the rated 2666 MT/s speed. Installation follows the usual So-DIMM slot procedure.

Suits Synology NAS owners adding memory.

This module suits administrators upgrading a compatible Synology NAS or appliance that accepts non-ECC DDR4 So-DIMMs. It will not meet the needs of buyers who require error-correcting code memory for data-integrity workloads. Systems that demand registered or buffered DIMMs cannot use this part. Buyers with desktop motherboards needing full-size DIMMs should look at a different form factor.

2666 MT/s DDR4 speed rating

The decisive specification is the 2666 MT/s DDR4 speed rating paired with non-ECC operation. Verify that your target device supports this exact speed and non-ECC So-DIMM modules before purchase. The 4 GB capacity is fixed and cannot be expanded on the module itself. Matching these two parameters determines whether the upgrade will function correctly.

Questions about this item

How can I confirm the DDR4-2666 So-DIMM is running at the correct speed after installation?

Enter the system BIOS or use a hardware monitoring utility to verify the memory frequency reads 2666 MT/s and that the module is detected as non-ECC.

What is included with the Synology DDR4-2666 Non-ECC So-DIMM 4GB and what must be purchased separately?

The package contains the single 4 GB So-DIMM module only; any additional modules for dual-channel configuration or tools for laptop disassembly are sold separately.

Which capacity of the Synology DDR4-2666 Non-ECC So-DIMM should I choose for my upgrade?

Select the 4 GB version if your system has a single slot or you need a modest capacity increase; add a second identical module if the platform supports two slots.
