A-Tech 4GB DDR4 2133MHz SODIMM Laptop RAM

4GB DDR4 2133MHz SODIMM for Laptop Upgrade

This 4GB DDR4 SODIMM module operates at 2133MHz with a CAS latency of CL15 and runs at the standard 1.20V. It uses a 260-pin form factor and is built with major brand chips for broad compatibility with AMD and Intel laptop platforms. The unbuffered, non-ECC design suits mainstream notebook and all-in-one systems needing a straightforward memory increase. It replaces Dell part numbers A8547952, A8707071, A8860718, SNPFDMRMC/4G, and SNPNC8DFC/4G.

Sustained Load Behaviour

Under continuous workloads the module maintains its rated 2133MHz speed and CL15 timings at the standard 1.20V. The unbuffered design and major brand chips provide stable data throughput for extended multitasking sessions without thermal throttling or voltage deviation. Quality assurance testing verifies reliable operation during prolonged use typical of everyday productivity and media tasks.

Capacity Determines Fit

The single 4GB capacity is the key specification that decides whether this module meets your system's memory requirement. Buyers needing more than 4GB per slot or a higher total system memory should look for larger modules. This part is not suited for systems that require ECC error correction or registered memory architectures.
