16 GB DDR4 SODIMM for Acer Aspire 5

This 16 GB DDR4 2400 MHz module is built for Acer Aspire 5 models including AN515-43-R0YM, AN515-43-R1QT, AN515-43-xxx and AN515-52-xxx. It uses a 260-pin SO-DIMM form factor, runs at 1.2 V and carries a CL17 latency rating. The kit contains a single unbuffered non-ECC stick.

Capacity headroom and dual-channel limits

The laptop supports a maximum of 32 GB across two sockets so this module fills half that ceiling. Running a single stick operates in single-channel mode; adding a second identical module enables dual-channel bandwidth. All installed memory will run at the speed of the slowest module or the processor limit.

Upgrading from lower-capacity configurations

The upgrade replaces a smaller factory stick or an empty slot and is most effective when paired with a matching module for dual-channel operation. A 64-bit operating system is required to address more than 4 GB. Buyers who need more than 32 GB total capacity or registered ECC memory cannot use this product.

Questions about this item

Will this 16 GB DDR4 2400 CL17 SODIMM run at the same speed if I keep my existing slower memory installed?

All installed memory will run at the speed of the slowest module or the processor's maximum capability, so mixing speeds forces the new stick to downclock.

How can I verify the 16 GB module is recognised at 2400 MHz after installation?

Check the memory speed in BIOS or with a tool such as CPU-Z; it should report 2400 MHz and CL17 timings for the new stick.

Does the single 260-pin SODIMM come with any extra parts or do I need to buy a second stick for dual-channel?

The package contains only one 16 GB memory stick; a second identical module must be purchased separately to enable dual-channel operation.
