16GB DDR4 SODIMM for Acer Aspire 5

This 16GB DDR4 2400 SO-DIMM module is built for specific Acer Aspire 5 notebooks. It targets owners of the A515-54-51DJ, A515-54-5649, and A515-54-56ST models who need a direct memory upgrade. The stick delivers 16GB capacity in a single unbuffered, non-ECC package.

Check your notebook model and slot count

Verify your exact model number matches the A515-54 series listed before ordering. The system supports a maximum capacity of 20GB across only one memory socket. Since this module occupies the sole slot, any existing memory must be removed to install it.

Single stick enables full 16GB upgrade

The package contains one 260-pin RAM stick rated at CL17 timing and 1.2V voltage. Installing this module brings the notebook to its 16GB configuration, leaving 4GB headroom to the 20GB limit. All memory will operate at the slowest installed speed or processor capability. A 64-bit operating system is required to address the full capacity.

Questions about this item

Does the CM2048642400SO kit include anything besides the single 16 GB stick?

The package contains one 260-pin DDR4 SO-DIMM module; no extra cables, brackets or tools are supplied.

Should I choose the 16 GB module or a smaller capacity for my Aspire 5 A515-54-51DJ?

The notebook supports up to 20 GB total with one socket, so the 16 GB stick leaves room for the existing 4 GB module while maximising capacity.

Will the CL17 2400 MHz rating run at that speed once installed in the A515-54-5649?

The system will operate the memory at the lowest speed among the installed modules and the CPU capability, so actual throughput may be lower than 2400 MHz.
