4 GB DDR3L SODIMM for Acer Aspire

This 4 GB DDR3L SODIMM is built for the Acer Aspire v5-561p-5451, V5-561p-5856 and V5-561p-6675 notebooks. It adds 4 GB of system memory at 1600 MHz. The module is unbuffered, non-ECC and runs at 1.35 V. Buyers needing more than 16 GB total capacity or a second stick for dual-channel operation should look elsewhere.

Plug-in installation with 204-pin key

Installation is a simple push into the 204-pin slot; no tools or firmware steps are required. The single-rank 1Rx8 layout avoids density conflicts that sometimes cause boot failures on these models. A mismatch in voltage or pin count is the only common issue, so verify the notebook uses DDR3L before fitting.

4 GB module in a two-slot 16 GB system

Each notebook accepts two SODIMMs up to 16 GB total, so this 4 GB stick leaves room for one more module. It handles everyday multitasking and light workloads comfortably. Heavy virtualisation or large media projects will exhaust the 4 GB headroom quickly.

Questions about this item

How do I verify the module is running at 1600 MHz with CL11 timing after installation?

Open Task Manager or CPU-Z and confirm the memory shows DDR3-1600 with 11-11-11 timings at 1.35 V.

What comes in the package and do I need any extra parts for my Acer Aspire v5-561p-5451?

One 4 GB DDR3L SODIMM stick is included; no additional parts are required for the listed Acer models.

Should I choose the 4 GB stick or add a second one to reach the 16 GB maximum?

Each slot accepts up to 8 GB; a single 4 GB module works alone, and adding a matching stick later doubles capacity.
