Synology DDR4 UDIMM Memory Modules

Choose the right memory for your Synology system

Upgrade your compatible Synology system with a DDR4 UDIMM module. Select the exact part number for your NAS and its installed memory. Capacity alone does not establish compatibility.

Highlights

• 4GB to 16GB options
• ECC and non-ECC options for their specified systems.
• Compatibility is specific to each module part number.

Key Features

Which module should I choose?

The Specs tab lists the supported models for each option. D4EU02-16G covers the documented D4EU01-16G platforms and adds newer supported RackStation models.

Can I mix old and new modules?

For a configuration with several modules, all installed modules must share the same model number. A successor that supports the same NAS should be used for a new installation or a complete matched set. It is not a matching add-on to an older module. Share your NAS model and installed part number with us before ordering an expansion.

Summary

Choose by exact module part number and supported system. We can help check a suitable matched configuration before you order.
