Targeted laptop memory upgrade

This 8 GB DDR4 SO-DIMM module is built for Acer Aspire Nitro and Aspire 7 models listed in the specifications. It suits owners of those machines who need a single stick to raise total memory without replacing existing modules. The stick runs at 2666 MHz with CL19 timing at 1.2 V.

Fits two-slot systems

The compatible laptops provide two memory sockets and support up to 64 GB total capacity. Adding this unbuffered, non-ECC 260-pin stick occupies one slot and leaves the second free for a matching module later. All installed memory will operate at the speed of the slowest module or the processor limit.

Replaces lower-capacity DDR4 SO-DIMMs

The upgrade is worthwhile when the factory configuration shipped with 4 GB or 8 GB in a single channel and the user wants more headroom for multitasking. It does not suit buyers who need ECC, registered DIMMs, or a different DDR generation.

Questions about this item

Will the 1.2V DDR4 2666 CL19 rating limit sustained throughput under heavy load?

The module runs at 1.2V with CL19 timings at 2666 MHz; sustained throughput is governed by the CPU memory controller and thermal limits of the laptop chassis, not by the stick itself.

Does the unbuffered SO-DIMM generate noticeable heat or fan noise during all-day operation?

Without a heat spreader the stick relies on airflow inside the Acer Aspire Nitro or Aspire 7 chassis; typical loads add minimal heat and no audible noise beyond the existing cooling system.

Must the laptop already have a free 260-pin DDR4 slot and support 8GB modules to use this upgrade?

Yes — the target Acer models provide two 260-pin SO-DIMM sockets supporting up to 64GB total, so an available slot and 64-bit OS are required.
