System-Specific DDR4 SODIMM for Acer Aspire

This 16 GB DDR4 module is built for Acer Aspire V5 V5-591G-74Mj E5-575-51Gg E5-774G-570J notebooks. It arrives as a single 260-pin SO-DIMM stick rated at 2133 MHz with CL15 timing and 1.2 V operation. The part is unbuffered, non-ECC and uses a 2Rx8 rank configuration.

DDR4 2133 MHz platform ceiling

The memory runs at the standard DDR4 2133 MT/s data rate, so the system memory controller will not exceed this speed regardless of faster modules installed alongside it. Total capacity is limited to 32 GB across the two available sockets, so a single 16 GB stick leaves one slot open for a matching upgrade.

16 GB single-stick capacity

The 16 GB density determines whether this upgrade fills a slot or completes the maximum 32 GB supported by the listed Acer models. Buyers who need the full 32 GB must add a second identical module, while those replacing a smaller stick gain immediate headroom for multitasking and larger workloads.

Questions about this item

Should I pick the 16GB stick or add a second one for 32GB?

The Acer Aspire models listed support a maximum of 32GB across two SODIMM sockets, so a second 16GB module will fill the limit.

What does the 2133MHz rating deliver in my laptop?

The module runs at DDR4 2133 with CL15 timing and 1.2V, matching the speed the supported Acer platforms expect from factory memory.

Does the 260-pin DDR4 SO-DIMM fit every Acer Aspire V5 and E5 model listed?

Yes, the 260-pin DDR4 SO-DIMM form factor is the standard slot used by the V5-591G, E5-575 and E5-774G series.
