NEMIX RAM 32GB (2x16GB) DDR4 2666 ECC Unbuffered SODIMM CL19 1.2V 260-PIN memory upgrade

Capacity and fit

This kit provides 32 GB of DDR4 2666 memory in two 16 GB SODIMM modules. It is built for Synology DiskStation DS3617xsII systems that accept 260-pin ECC unbuffered memory. The 2Rx8 organisation and CL19 timing match the platform requirements listed by the supplier.

Sustained-load behaviour

Modules are stress-tested under load to verify stability during continuous operation. ECC circuitry detects and corrects single-bit errors that can accumulate in long-running NAS workloads. The 1.20 V operating voltage keeps power draw consistent while the dual-rank layout supports steady throughput.

Pre-order checks

Confirm that your Synology unit uses DDR4 SODIMM slots and supports ECC unbuffered modules before ordering. Verify the maximum memory capacity per slot and the total number of available slots in the specific model. Ensure the system BIOS or firmware recognises 2Rx8 modules at 2666 MT/s.
