Samsung DDR4 ECC SODIMM Upgrade

This 8 GB DDR4 2666 ECC SODIMM module targets owners of Samsung servers, workstations or NAS units that require 260-pin unbuffered memory with error correction. It runs at 1.2 V with CL19 latency and a single 1Rx8 rank.

Replaces non-ECC or lower-capacity SODIMMs

Swapping standard unbuffered SODIMMs for this ECC version adds data-integrity protection for mission-critical workloads. The jump is worth it when your Samsung platform supports ECC and you need to correct single-bit errors without registered buffering.

Verify 260-pin DDR4 slot and ECC support

Confirm the system accepts 260-pin DDR4 SODIMMs at 2666 MT/s and that the BIOS enables ECC on unbuffered modules. Check the motherboard manual for maximum capacity per slot and total supported memory before ordering.

Questions about this item

Will the 260-pin DDR4 SODIMM fit my Synology NAS slot?

The module uses the standard 260-pin DDR4 SODIMM form factor, which matches the memory slots in compatible Synology systems listed for this part.

Do I need to configure anything in BIOS after installing this ECC unbuffered module?

Installation is a physical insert into the SODIMM slot; most supported platforms enable ECC automatically, but check the system manual to confirm ECC is active in BIOS.

How do I know when this 8GB DDR4 2666 CL19 stick should be replaced?

ECC modules report correctable errors in system logs; a rising error count or repeated uncorrectable errors indicates the stick should be swapped out.
