Targeted DDR4 SODIMM for select Acer Aspire 5

This 16 GB DDR4 2400 CL17 module uses a 260-pin SO-DIMM form factor and runs at 1.2 V without ECC or buffering. It is built for the Acer Aspire 5 A715-72G, A715-74G, AN515-42 and AN515-53-70AQ series where a single stick can fill one of the two available slots.

Upgrades from smaller or slower factory modules

The laptop platform supports up to 32 GB across two sockets, so this stick replaces an 8 GB or 4 GB original and adds headroom for multitasking. The jump is worth it when the system currently runs in single-channel mode or hits capacity limits during heavy browser or creative workloads.

Straightforward slot installation

Insert the module at an angle into the SODIMM socket until the side clips lock, requiring no tools beyond a screwdriver for the bottom cover. The main issue arises if an existing stick has a different speed or latency, because the memory controller will downclock both modules to the slowest timing.

Questions about this item

Does this 260-pin DDR4 SODIMM fit the single open slot in my Acer Aspire 5 A715-72G?

Yes, the module is a 260-pin DDR4 SODIMM and the compatible systems list includes the A715-72G series, which uses that slot type.

What is the correct way to seat this 16 GB stick so the side clips engage?

Align the notch on the module with the key in the slot, insert it at an angle until the contacts are fully hidden, then press down evenly until both clips snap into the side notches.

If I later add a second 16 GB module to reach the 32 GB maximum, will I need to replace this one?

No, you can keep this stick and add a matching 16 GB DDR4 2400 CL17 SODIMM; the system supports two sockets up to 32 GB total.
