DDR4 ECC SODIMM is error-correcting memory in the small-outline form factor — designed for NAS appliances, compact and mobile workstations, and embedded and industrial systems that need ECC protection but have no room for full-size DIMMs. This page lists every DDR4 ECC SODIMM NEMIX RAM supplies, from DDR4-2133 to DDR4-3200. Each module is a 260-pin, 1.2V unbuffered SODIMM with a 72-bit ECC data path (64 data bits plus 8 check bits), so the system can detect and correct memory errors — the reason NAS vendors specify ECC memory for always-on storage.

What is on this page

Single modules in 8GB, 16GB and 32GB, in 1Rx8 and 2Rx8 organizations, plus matched kits up to 128GB (4x32GB). DDR4-2666 and DDR4-3200 make up the largest share, with DDR4-2400, 2933 and 2133 for earlier platforms. Narrow the list with the Technology Speed, Module Density, Kit and Rank filters. Many listings are matched to a specific NAS, workstation or board, and many more are listed by OEM part number — Synology D4ES and D4ECSO, QNAP RAM-DR4EC-SO, ASUSTOR AS-GECD4, Dell SNP, Supermicro MEM-DR4-ES, Samsung, SK hynix and Micron parts. Searching your model or part number at the top of the page is the fastest way to find them.

Where DDR4 ECC SODIMM is used

DDR4 ECC SODIMM is commonly paired with AMD Ryzen Embedded R-series and V-series NAS and edge processors, Intel Atom C3000 and Xeon D, Intel Xeon E and W-1200E embedded platforms, and Xeon W mobile workstations. System-matched listings on this page include Synology DiskStation DS723+, DS923+, DS1621+, DS1821+, DS1823xs+, DS2419+II, DS2422xs+, DS3617xsII and DS3622xs+ and RackStation RS822+ and RS1221+; QNAP NAS; ASUSTOR LOCKERSTOR 10 Pro; Dell Precision mobile workstations; Supermicro X12SCV boards and the SYS-E300-12C IoT SuperServer; and ASRock Rack E3C256D4I-2T and ASRock Industrial IMB-V2000 boards.

Choosing the right DDR4 ECC SODIMM

ECC SODIMM is not interchangeable with full-size ECC UDIMM or RDIMM, and DDR4 SODIMM is keyed differently from DDR5 SODIMM. ECC is active only where the processor, chipset and BIOS support it; most consumer laptops and many small desktops do not, and some NAS models accept only the vendor-listed ECC modules. Match density and rank to the modules already installed, and use identical modules when filling every slot — many NAS units run dual-channel only with a matched pair. A faster module clocks down to the platform's supported speed. For non-ECC laptop memory, see DDR4 Non-ECC SODIMM. If you are unsure, send us the system model or the OEM part number and we will confirm fitment before you order.
