Synology RS1619xs+ memory kit

This 32GB kit contains two 16GB DDR4 modules built for the Synology RackStation RS1619xs+. Each stick runs at 2400MHz with CL17 timing and 1.2V power draw. ECC protection and unregistered operation match the platform requirements exactly.

Sustained workload behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, preventing silent data corruption in always-on services. The unregistered design keeps latency low while the 2Rx8 organisation maintains signal integrity across all four DIMM slots.

Capacity ceiling

The RS1619xs+ supports a maximum of 64GB across four sockets, so this 32GB kit fills half the available capacity. Buyers who need the full 64GB limit will require a second identical kit to populate the remaining slots.

Questions about this item

How much power does this 1.2 V DDR4 kit draw when the Synology RS1619xs+ runs 24/7?

Each module operates at 1.2 V, the standard DDR4 voltage, so total power draw stays low even under continuous load in the RS1619xs+.

Does the RS1619xs+ need any firmware update or special BIOS setting before I install these two 16 GB ECC DIMMs?

The kit is guaranteed compatible with the Synology RackStation RS1619xs+; no extra firmware steps are required beyond the normal memory installation procedure.

Can I keep the two 8 GB sticks that came with my RS1619xs+ and add this 32 GB kit to reach the 64 GB maximum?

Yes, the RS1619xs+ has four slots and supports up to 64 GB, so you can populate the two free 288-pin slots with this 2×16 GB kit alongside the original modules.
