A-Tech 16GB DDR4 2666MHz ECC SODIMM

This 16GB DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It targets server and workstation laptops that require ECC unbuffered memory for data integrity. The 260-pin SO-DIMM form factor fits compatible mobile platforms from AMD and Intel.

Verify DDR4 2666 ECC SO-DIMM support before ordering

Check that your laptop or mobile workstation accepts 260-pin DDR4 SO-DIMMs with ECC unbuffered operation at 1.2V. Confirm the maximum supported capacity per slot and total system limit in the manufacturer documentation. This module replaces Hynix HMA82GS7CJR8N-VK and HMA82GS7DJR8N-VK part numbers.

Single 16GB stick adds ECC capacity without

The 2Rx8 organisation delivers 16GB in one module, leaving additional SO-DIMM slots free for future expansion. Unbuffered ECC design works with standard mobile chipsets that support error correction. Standard 1.2V DDR4 voltage ensures compatibility with typical laptop power delivery.

Questions about this item

What is included in the box and what must be purchased separately?

The box contains a single 16 GB DDR4 2666 MHz ECC SODIMM module; no extra cables, brackets or tools are supplied.

How do I decide between the available capacities or versions of this module?

This listing is for one 16 GB stick at 2666 MHz CL19; choose it when your laptop or workstation needs a single ECC unbuffered SODIMM at that speed.

What does the 2666 MHz rating mean once the module is installed in a real machine?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency at 1.20 V, delivering that data rate when the system memory controller supports it.
