Targeted Synology Upgrade

This 8 GB DDR4 2400 module is built specifically for the Synology RackStation RS1619xs+. It delivers ECC protection and unregistered DIMM signalling in a single 288-pin stick, matching the platform's native memory architecture.

Fills Empty Slots

The server ships with four DIMM sockets and supports up to 64 GB total capacity. Adding this stick expands usable memory for virtual machines, containers or large file caches when the existing configuration leaves slots open.

Steady Multi-Task Throughput

CL17 timing at 1.2 V keeps latency predictable while ECC corrects single-bit errors during long backup or scrub jobs. The unbuffered design avoids registered-module overhead, so sustained workloads maintain consistent bandwidth without extra buffering delay.

Questions about this item

Does the 288-pin DDR4 DIMM fit the four memory slots in the Synology RackStation RS1619xs+?

Yes, the 288-pin DDR4 DIMM matches the four slots in the RS1619xs+ and the system supports up to 64 GB total.

How do I install the module and what step is often missed?

Power down the RackStation, open the chassis, align the notch on the 288-pin DIMM with the slot key, press firmly until the side clips lock, then verify the new 8 GB appears in DSM.

Will the ECC non-registered 2Rx8 module need any firmware updates or replacement later?

No firmware update is required; the module runs at 1.2 V with CL17 timing and is covered by the manufacturer's limited lifetime warranty.
