32 GB DDR4 2666 MHz ECC kit for Synology RS1619xs+

This 32 GB kit contains two 16 GB DDR4 2666 MHz ECC unbuffered UDIMM modules. It is built for Synology RackStation RS1619xs+ and RS2818RP+ units that support ECC memory. The modules operate at 1.2 V with CL19 latency and use a 288-pin 2Rx8 layout.

Verify your RackStation model

Confirm the unit is an RS1619xs+ or RS2818RP+ because the kit is validated only for those models. Check how many memory slots are free and whether the system already uses ECC UDIMM modules. The memory runs at 2666 MHz and is backward compatible with 2133 MHz and 2400 MHz bus speeds.

Kit includes two matched modules for dual-channel

The pair of 16 GB sticks enables dual-channel bandwidth when both slots are populated. JEDEC and RoHS compliance ensures a warranty-safe upgrade without extra software or cables. No heat spreader is fitted, so standard chassis airflow is sufficient.

Questions about this item

Does the kit include both 16GB modules or do I need to buy a second stick separately?

The kit contains two 16GB DDR4 2666MHz ECC UDIMM modules for a total of 32GB, so nothing else is required.

Should I choose this 32GB CL19 kit or a lower-capacity option for my RS2818RP+?

This 32GB (2x16GB) CL19 kit matches the supported DDR4 2666MHz speed and ECC unbuffered specification for the RS2818RP+ and RS1619xs+.

Will the 2666MHz rating actually run at that speed once installed in my RackStation?

The modules are rated PC4-21300 2666MHz CL19 at 1.2V and are backward compatible with 2133MHz and 2400MHz if the system requires a lower speed.
