Synology DDR4 SODIMM Memory Modules

Choose compatible memory for your Synology NAS

Expand your supported Synology NAS with a DDR4 SODIMM memory module. Choose the exact part number for your NAS model and installed memory, with 4GB, 8GB and 16GB options.

Highlights

• Synology modules with model-specific NAS compatibility.
• ECC and non-ECC options for their supported systems.
• The current 4GB ECC option is D4ES04-4G.

Key Features

D4ES04-4G replaces D4ES01-4G

We now supply D4ES04-4G in place of D4ES01-4G for the compatible NAS models listed in Specs. The new module supports the older module’s documented NAS platforms and newer systems including RS1226+, RS1226RP+, RS826+ and RS826RP+.

Matched modules for an existing installation

When several modules are installed together, all must share the same model number. Do not mix D4ES04-4G with D4ES01-4G. Use the current module for a new installation or replace the full matched set. If you need to expand an existing configuration, tell us the NAS model and installed part number before ordering.

Check the exact option

Modules with the same capacity can have different compatibility. The Specs tab lists supported systems for each part number. ECC and non-ECC modules are separate options.

Summary

Select the supported module for your exact Synology system and check the installed memory before upgrading.

Synology DDR4 SODIMM Memory Modules

These Synology DDR4 SODIMM modules provide memory upgrades for the compatible systems shown below. Each option has its own supported NAS models and ECC configuration. Select by exact part number rather than capacity alone. Before adding memory to an existing system, check the installed module label and the supported slot configuration. Use identical module model numbers in a configuration with several modules, including when replacing older memory.
