Synology RS18017xs+ Memory Upgrade

This 16 GB kit delivers two 8 GB DDR4 registered DIMMs validated for the Synology RackStation RS18017xs+. ECC protection and registered buffering maintain data integrity in the four-slot chassis that supports up to 128 GB total capacity.

Sustained Load Stability

Registered signalling reduces electrical load on the memory controller during continuous operation. CL15 timing at 2133 MHz and 1.2 V voltage provide consistent throughput for long-running storage and virtualization workloads without the jitter seen in unbuffered modules.

Build and Daily Use

The 288-pin modules ship without heat spreaders, keeping height low for dense server enclosures. Major-brand DRAM chips and a 2Rx8 organisation ensure reliable seating in all four DIMM slots, while the matched pair simplifies dual-channel population for immediate recognition.

Questions about this item

How much heat or power draw does the 1.2V DDR4 2133MHz registered ECC kit produce during continuous operation?

The modules run at 1.2 volts with no heat spreader, so power draw and heat output stay low during all-day workloads in the Synology RS18017xs+.

What must my Synology RS18017xs+ already have for this 2x8GB 288-pin kit to work?

The RS18017xs+ needs free DDR4 ECC registered DIMM slots — up to four sockets supporting 128 GB total — and a BIOS that accepts 2133 MHz CL15 2Rx8 modules.

Will these 2133MHz CL15 registered sticks run alongside older DDR4 modules I keep in the RS18017xs+?

Yes, if the existing sticks are also DDR4 ECC registered at 1.2 volts; the system will clock all modules to the slowest common speed and latency.
