16GB ECC kit for Synology RS18016xs+

This 16GB kit contains two 8GB unregistered ECC DIMMs built for the Synology RackStation RS18016xs+. Each module runs at DDR3 1600 (PC3 12800) with CL11 timing at 1.5V. The 2Rx8 organisation allows dual-channel operation when both sticks populate matched slots. It is not for systems that require registered memory or a different DDR generation.

Check slots and maximum capacity first

The RS18016xs+ provides four DIMM sockets and supports up to 32GB total. Verify how many slots are already occupied before ordering. This kit adds 16GB; if all four sockets are full you must remove existing modules. The server only accepts unregistered ECC DDR3 DIMMs, so registered or non-ECC sticks will not work.

Standard voltage and unbuffered design

Operating at the standard 1.5V for DDR3, the modules draw typical power for this memory class. Without a heat spreader fitted, they rely on chassis airflow for cooling. Unbuffered construction keeps electrical load on the memory controller low, which helps maintain stable thermals and quiet operation in a populated server chassis.

Questions about this item

What comes in the box and do I need to buy anything else to install these in my Synology Rackstation Rs18016Xs+?

The package contains two 8GB 240-pin DDR3 ECC unregistered DIMM sticks. No extra parts or tools are required for installation in the compatible system.

Should I choose the 16GB kit or a different capacity for my Rs18016Xs+ which supports up to 32GB across four slots?

The 16GB (2x8GB) kit fills half the slots and leaves two free for a future upgrade to the 32GB maximum. If you need the full 32GB now, buy two of these kits.

What does the DDR3 1600 (PC3 12800) rating mean for actual performance in the Rs18016Xs+?

The modules run at 1600 MHz with CL11 11-11-11 timing at 1.5V. The Rs18016Xs+ memory controller operates them in dual-channel mode using the ECC unregistered DIMMs supplied.
