16GB ECC DDR4 SODIMM for server laptops

This 16GB DDR4 2666MHz ECC SODIMM is built for mobile workstations and servers that require error-correcting memory. The unbuffered 2Rx8 module operates at 1.2V with CL19 latency. It targets IT professionals and engineers maintaining Dell systems using part numbers AA075846, AA297490, AA318912 or SNPPD4K8C/16G. Builders needing non-ECC memory for consumer laptops should look elsewhere.

Capacity and headroom for ECC workloads

The single 16GB rank provides substantial headroom for virtualisation, database caching and multi-threaded compilation on supported platforms. ECC protection corrects single-bit errors that would otherwise corrupt data in long-running server tasks. Systems limited to 16GB per slot or lower maximum memory ceilings will not benefit from additional density beyond this module.

Major-brand chips and lifetime support

A-Tech assembles the module with major-brand DRAM components and validates each stick through quality-assurance testing. The package includes only the SODIMM itself; no brackets, adapters or software utilities are bundled. US-based technical support is available for compatibility verification before installation and for troubleshooting afterwards.

Questions about this item

Will this ECC SODIMM run with non-ECC DDR4 2666 MHz modules already in my laptop?

Mixing ECC and non-ECC DDR4 2666 modules is not recommended; the system will typically disable ECC or fail to boot, so match all slots with identical ECC unbuffered 1.2 V CL19 sticks.

How can I confirm the module is detected at DDR4 2666 CL19 with ECC active after installation?

Open BIOS or a tool like CPU-Z and verify the memory shows 2666 MT/s, CL19 timings, 1.20 V and ECC status as enabled or active.

Does the package include only the single 16 GB 260-pin SODIMM or are screws or adapters supplied?

The box contains one 16 GB 260-pin DDR4 2666 ECC unbuffered SODIMM; no screws, adapters or extra parts are included.
