Synology DDR4 RDIMM Memory Modules

Choose the right memory for your Synology system

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

Highlights

• 16GB to 64GB RDIMM options
• ECC registered memory for supported enterprise 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. D4ER02-32G is the current 32GB option for the documented D4ER01-32G platforms. FS6400 uses a different supported module such as D4RD-2666-32G.

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.
