4GB DDR3 SODIMM for Synology NAS

This 4GB DDR3 1600 CL11 SODIMM module is built for Synology NAS models RS815RP+, DS2015xs, DS2415+, RS2416+ and RS2416RP+. It uses 204-pin unbuffered non-ECC memory running at 1.5V to match the original OEM specification. The single-rank 1Rx8 design installs directly into the available memory slot.

NAS owners adding capacity; not for ECC systems

Owners of the listed Synology units who need more memory for virtual machines or heavy file workloads will find this upgrade matches the factory configuration. Buyers whose NAS requires ECC registered DIMMs or a different voltage must choose a different module. Systems outside the compatibility list are not supported.

Single 4GB DDR3 1600 CL11 SODIMM stick

The decisive specification is the single 4GB stick rated at DDR3 1600 with CL11 latency in the 204-pin SODIMM form factor. It replaces Synology part number RAM1600DDR3-4G and operates at the standard 1.5V JEDEC voltage. Matching this exact speed, voltage and form factor determines whether the module will work.

Questions about this item

Does the CL11 latency limit throughput when the NAS runs sustained workloads?

CL11 is the rated CAS latency for this DDR3 1600 module; it sets the timing floor for every access cycle.

How much heat does the 1.5 V DDR3 SODIMM produce during all-day operation?

The module runs at standard 1.5 V without a heat spreader; typical DDR3 SODIMM power stays low enough for passive cooling inside Synology NAS enclosures.

Which Synology NAS models must I already own for this 204-pin DDR3 1600 SODIMM to work?

Compatible systems are RS815RP+, DS2015xs, DS2415+, RS2416+ and RS2416RP+; the module replaces Synology part RAM1600DDR3-4G.
