Synology RS3618xs Memory Upgrade

This 16 GB DDR4 module is built for the Synology RackStation RS3618xs. It adds capacity to a NAS that supports up to 64 GB across four slots. The unregistered ECC design matches the system's requirements for data integrity. Buyers needing registered DIMMs or a different pin count cannot use this kit.

Sustained Load Behaviour

ECC circuitry corrects single-bit errors during continuous read and write cycles. The CL17 timing and 1.2 V operation keep latency stable under long workloads. No heat spreader is fitted, so airflow in the chassis manages module temperature. Systems that demand registered buffers or higher voltage modules will not accept this part.

Deciding Specification

The module runs at DDR4 2400 (PC4 19200) with a 2Rx8 organisation. This speed and rank configuration must match the motherboard's qualified vendor list. A different frequency, rank layout or voltage will prevent the NAS from booting.

商品問答

How much power does the 1.2V DDR4 2400 module draw under continuous load?

The module operates at 1.2 volts and is rated DDR4 2400 (PC4 19200) with CL17 timings; actual power draw depends on the Synology RS3618xs memory controller and workload.

Does the RS3618xs require any specific BIOS setting or firmware version to recognise this ECC unregistered DIMM?

The stick is validated for the Synology RackStation RS3618xs and RS4017xs+; the NAS firmware handles ECC unregistered memory automatically with no extra configuration.

Can I mix this 2Rx8 16GB stick with the original 8GB modules in the four RS3618xs slots?

The RS3618xs supports up to 64GB across four slots; mixing ranks is allowed but all slots run at the speed of the slowest module, so the 2400MHz stick will down-clock if existing memory is slower.
