Synology RackStation RC18015xs+ compatible memory

This 16GB kit contains two 8GB DDR3 ECC unbuffered DIMMs built for the Synology RackStation RC18015xs+. The modules run at 1600 MHz with CL11 timings and 1.5V voltage. They are designed for server workloads that require error correction and stable operation. The kit fills two of the system's four memory slots.

Verify four-slot DDR3 ECC unbuffered support

Confirm the RackStation has four available 240-pin DDR3 slots and accepts unregistered ECC modules before ordering. The system maximum is 32GB, so this 16GB kit leaves room for expansion. Mixing with existing registered or non-ECC memory is not supported. Ensure the BIOS or firmware recognises 2Rx8 organisation.

Dual-channel kit with lifetime exchange coverage

The matched pair enables dual-channel operation for improved bandwidth in the compatible Synology server. Computer Memory Solutions provides a lifetime exchange or repair warranty against manufacturing defects when purchased directly. Product appearance may vary from the reference image. No additional software or accessories are included.

Questions about this item

What comes in the box and is anything else needed for installation?

The package contains two 8 GB DDR3 DIMMs. No extra parts are required; they install directly into the four DIMM slots of the Synology RackStation RC18015xs+.

Should I pick this 16 GB kit or a different capacity for the RC18015xs+?

The RC18015xs+ supports up to 32 GB across four slots, so this 16 GB (2×8 GB) kit fills half the slots and leaves room for a second identical kit later.

What does the DDR3 1600 CL11 rating mean once the modules are running in the server?

The modules operate at 1600 MHz with 11-11-11 timings at 1.5 V, providing ECC error correction in dual-channel mode for the supported Synology system.
