Synology Inc. D4ER01-16G 16GB DDR4 ECC RDIMM NAS

Synology 16GB DDR4 ECC RDIMM

This Synology D4ER01-16G module adds 16GB of DDR4 ECC registered memory to compatible NAS systems. It is designed for owners of supported Synology Desktop NAS units who need to expand system memory for heavier workloads. The ECC RDIMM format helps maintain data integrity during intensive operations. Installation follows the standard procedure for the target NAS platform.

Suits Synology NAS owners needing ECC RDIMM

This upgrade suits administrators running virtual machines, Docker containers or large databases on a compatible Synology Desktop NAS. It is not for buyers whose NAS model only accepts unbuffered UDIMM modules or proprietary form factors. It is also not for users seeking to upgrade a non-Synology server or a workstation that requires a different memory generation or pin layout. Compatibility must be verified against the specific NAS hardware list.

16GB DDR4 ECC RDIMM capacity and type

The single specification that decides fitment is the 16GB DDR4 ECC RDIMM module type. Only NAS models qualified for this exact density, generation and registered ECC format will recognise and use the memory. Attempting to install it in a system limited to lower capacities, non-ECC memory or a different DDR generation will result in a non-booting or unstable device. Check the manufacturer's qualified vendor list before purchase.
