Targeted DDR3L SODIMM upgrade

This 4GB module is built for Acer Aspire V15 models V3-575-57MJ, V3-575-50TD and V5-591G-57GW. It uses a 204-pin DDR3L interface at 1600MHz with CL11 timing and 1.35V operation. The unbuffered, non-ECC design matches the original specification for these notebooks.

Steady throughput under load

The single-rank 1Rx8 layout with major-brand chips delivers consistent bandwidth during extended sessions. CAS latency of 11-11-11 keeps access times stable when the system sustains heavy multitasking or background tasks. Low-voltage DDR3L operation reduces thermal pressure on the memory controller over long periods.

Straightforward slot installation

Insert the stick into either of the two SODIMM slots until the side clips engage; no tools or firmware changes are required. The kit contains one 4GB module, so total capacity reaches 8GB if the second slot is already populated. Systems needing more than 16GB total cannot use this upgrade.

Questions about this item

How much power does the 1.35 V DDR3L module draw when the laptop runs all day?

At 1.35 V the SODIMM runs cooler and uses less power than standard 1.5 V DDR3, helping battery life during long sessions.

What must my Acer Aspire already have for this 204-pin stick to work?

A free DDR3L SODIMM slot and a BIOS that accepts 1600 MHz CL11 unbuffered non-ECC memory.

Will this 4 GB kit run beside the original 4 GB module in my V3-575 for 8 GB total?

Yes, the laptop supports two slots up to 16 GB, so adding this 1Rx8 stick to an existing module gives 8 GB dual-channel.
