Synology RS3617xs+ memory kit

This 64 GB kit contains four 16 GB DDR4 ECC unregistered DIMMs validated for the Synology RackStation RS3617xs+. The modules run at 2133 MHz with CL15 timings at 1.2 V and fill all four slots to reach the platform maximum of 64 GB.

Compatibility and slot check

Confirm your RS3617xs+ has four free 288-pin DDR4 slots before ordering, because the kit occupies every socket. The system requires ECC non-registered memory; registered or non-ECC modules will not work in this NAS.

Suited for full-capacity NAS upgrades

Ideal for administrators who need the full 64 GB supported by the RS3617xs+ for virtualisation or heavy file workloads. Not for buyers who want to keep existing sticks, need registered DIMMs, or are upgrading a different Synology model.

Questions about this item

Does the kit include only the four 16 GB DDR4 modules or are any tools or cables supplied?

The package contains four 16 GB DDR4 2133 MHz ECC unregistered DIMMs and nothing else; no tools or cables are included.

Should I pick the 64 GB four-module kit or a smaller capacity for my Synology RS3617xs+?

The RS3617xs+ has four slots and a 64 GB maximum, so the four-module 64 GB kit fills every slot and reaches the system limit.

What does the DDR4 2133 CL15 rating mean once the memory is installed in the RackStation?

The modules run at 2133 MT/s with 15-15-15 timings at 1.2 V, delivering the rated PC4 17000 bandwidth inside the RS3617xs+.
