  • 5V unbuffered design works with existing memory configuration

System-specific DDR3 upgrade

This 4 GB SODIMM module is built for Acer Aspire 5742G and 5745 notebooks. It targets owners of those models who need a straightforward memory replacement or expansion without compatibility guesswork. The stick is validated for the listed part numbers and installs in a standard 204-pin slot.

Capacity and headroom

The kit supplies a single 4 GB rank in a two-slot chassis that supports up to 8 GB total. One module fills half the maximum, leaving the second slot open for a matching stick if more capacity is required later. Workloads that exceed 4 GB will page to storage until a second module is added.

DDR3 1066 interface limits

The module runs at DDR3 1066 (PC3 8500) with CL7 timing at 1.5 V. Bandwidth and latency are fixed by that standard, so performance cannot scale beyond the memory controller’s native ceiling. Systems already populated with slower DDR3 will down-clock to the lowest common speed.

Questions about this item

Will this 204-pin DDR3 1066 module work in the second slot of my Acer Aspire 5742G alongside the original memory?

Yes, the laptop has two SODIMM slots and supports up to 8 GB total, so this 4 GB stick can be added to the existing module.

How can I verify the CL7 timing and 1.5 V voltage are active after installation?

Open CPU-Z or the BIOS memory tab; the SPD and real-time tabs will show DDR3-1066, 7-7-7 timings and 1.5 V.

Does the package include only the memory stick or are tools and a thermal pad supplied?

The box contains one 4 GB SODIMM stick; no tools, heat spreader or thermal pad are included.
