Synology DS2422+ memory upgrade

This kit provides 16 GB of DDR4 ECC SODIMM memory configured as two 8 GB modules. It is built for the Synology DS2422+ NAS and targets administrators who need error-correcting memory for data-integrity workloads. The 260-pin unbuffered design matches the system’s memory slots exactly. No heat spreaders are included.

Sustained 2666 MHz operation with ECC

The modules run at DDR4 2666 (PC4-21300) with a CAS latency of 19 and a voltage of 1.20 V. ECC circuitry detects and corrects single-bit errors during continuous read and write cycles. Unbuffered topology keeps latency low while the major-brand DRAM chips maintain signal integrity under prolonged load. The 1Rx8 organisation supports stable throughput for multi-user NAS services.

Tool-free SODIMM installation

Each module inserts vertically into the DS2422+ memory slots until the side latches click. The low-profile 260-pin form factor clears the chassis cover without force. Common issues are seating the module at an angle or forgetting to power down the NAS before opening the case. Following the Synology owner’s manual avoids both problems.

Questions about this item

Does the 1.20 V DDR4 2666 kit run hot or loud in a DS2422+ that operates 24/7?

The modules have no heat spreader and draw 1.20 V at DDR4 2666, so they add minimal heat and produce no noise in a continuously running DS2422+.

What must the DS2422+ already have for this 260-pin ECC SODIMM kit to work?

The DS2422+ needs free 260-pin DDR4 SODIMM slots that accept unbuffered ECC memory; the kit simply plugs into those slots.

Will the CL19 1Rx8 modules work alongside the original 8 GB stick already in my DS2422+?

Yes, the 1Rx8 CL19 2666 MHz modules are designed to run with the DS2422+ memory controller, so they operate together with the factory-installed stick.
