Targeted 16 GB DDR4 SODIMM upgrade

This 16 GB DDR4 2666 SODIMM is built for specific Acer Aspire Nitro and Aspire 7 notebooks listed in the compatibility data. It suits owners of those machines who want to add memory without guessing fit. Buyers with other laptops or desktop boards should not use this module.

DDR4 2666 speed and platform ceiling

The module runs at 2666 MHz (PC4 21300) with CL19 timing at 1.2 V. Installed memory will operate at the slowest speed among all modules and the processor capability. A 64-bit operating system is required to address more than 4 GB. The platform supports up to 64 GB across two sockets.

Unbuffered 260-pin stick, no spreader

The single 2Rx8 rank stick uses major-brand chips on an unbuffered non-ECC PCB without a heat spreader. Its low-profile 260-pin SO-DIMM form factor fits tight notebook slots. Mixing with other brands is possible but all memory will run at the lowest common speed.

Questions about this item

Should I choose the single 16GB stick or a different capacity for my Acer Aspire Nitro 5 AN517-51-56YW?

This module provides 16GB in one 260-pin SODIMM. Your laptop has two slots supporting up to 64GB total, so adding a second identical stick later will enable dual-channel performance.

What does the 2666MHz rating actually deliver once installed in the Nitro 5?

The memory will run at 2666MHz CL19 at 1.2V. If the CPU or existing RAM is slower, the system will downclock all modules to the lowest common speed automatically.

Is the DDR4 2666 SO-DIMM interface limited by the laptop's memory controller?

The 260-pin DDR4 SO-DIMM fits the Nitro 5's two slots. The platform caps at 64GB across both sockets, and all installed memory operates at the slowest module's speed.
