A-Tech 16GB DDR4 2133MHz CL15 ECC SODIMM 260-Pin 1.2V

Capacity & Compatibility

This 16 GB DDR4 SO-DIMM module runs at 2133 MHz with CL15 latency and operates at the standard 1.2 V. It uses a 260-pin layout and includes ECC error correction in an unbuffered design, making it suitable for compatible server or workstation laptops that require registered-style reliability without registered signalling. The sticks are validated as direct replacements for Dell part numbers SNP739XRC/16G, A8547957 and A8860720.

Thermals & Power

The module draws power only at the JEDEC-standard 1.2 V, so it adds minimal heat to a laptop chassis and does not require active cooling beyond the system's existing airflow. Because it is an unbuffered ECC design, there is no register chip to generate extra warmth, keeping thermal output comparable to ordinary non-ECC SO-DIMMs during typical workloads.

Chip Quality & Support

A-Tech fits each board with major-brand DRAM components and subjects every unit to a full quality-assurance test cycle before it ships. The manufacturer backs the module with a lifetime warranty and provides US-based technical support for installation or compatibility questions, giving buyers a direct path to assistance if the memory does not post in their specific platform. Builders who need registered RDIMMs or capacities above 16 GB per slot cannot use this module.
