Computer Memory Solutions 4GB DDR3 1066 SODIMM A34

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.
