Ready for Acer Nitro 5

This 8 GB DDR4 2666 SODIMM module is built for the Acer Aspire Nitro 5 models AN515-54-54W2 and AN515-54-51M5. It suits owners who need a single 8 GB stick to fill one of the two available slots. The unbuffered, non-ECC design matches the factory specification for these laptops.

Simple slot insertion

Installation requires opening the laptop base and pressing the 260-pin module into the SO-DIMM slot until the side clips lock. The low-profile design has no heat spreader, so clearance is rarely an issue. Mixing this stick with an existing module will force both to run at the slowest speed or timing present in the system.

Check slot count and OS

Verify your unit has a free SO-DIMM slot; the supported models provide two sockets with a 64 GB total ceiling. A 64-bit operating system is required to address more than 4 GB of memory. Confirm the existing module’s speed and latency if you plan to keep it installed alongside this one.

Questions about this item

How can I verify the CM1024642666SO is running at DDR4 2666 CL19 after installing it in my Nitro 5 AN515-54?

Open Task Manager, go to the Performance tab, select Memory and confirm the speed shows 2666 MHz; you can also run CPU-Z and check the SPD tab reads DDR4-2666 with 19-19-19 timings at 1.2 V.

What comes in the box with the CM1024642666SO and do I need any extra parts for my Acer Aspire Nitro 5?

The package contains one 8 GB 260-pin DDR4 SO-DIMM stick; no additional brackets, screws or cables are required for the Nitro 5 AN515-54-54W2 or AN515-54-51M5.

Should I choose the single 8 GB CM1024642666SO or add a second stick to reach the 64 GB maximum on my two-slot Nitro 5?

The laptop has two SO-DIMM slots and supports up to 64 GB total; one 8 GB module works immediately, and adding a matching stick later enables dual-channel mode for higher bandwidth.
