2GB DDR3 1066MHz SODIMM Upgrade

This 2GB DDR3-1066 SODIMM module is designed for notebook memory upgrades. It operates at 1.5V with CL7 latency and uses a 204-pin unbuffered, non-ECC layout. The single 1Rx8 rank stick targets owners of compatible Acer Aspire One and Aspire 5734Z notebooks seeking a direct replacement.

Lifetime Warranty and Guaranteed Compatibility

The module carries a limited lifetime warranty from Computer Memory Solutions when purchased directly from the manufacturer. CMS guarantees compatibility with the specific Acer models listed in the description. The package contains one memory stick; product appearance may vary from reference images.

Handles Standard Notebook Workloads

At 1066MHz with 7-7-7 timing, this memory comfortably handles everyday computing tasks and multitasking within the 2GB capacity limit. It reaches its ceiling with memory-intensive applications or when the operating system restricts usable memory, such as the 1GB limit imposed by Windows 7 Starter on this platform.

Questions about this item

Will the 204-pin DDR3 SODIMM need any cleaning or re-seating after long-term use?

The module has no heat spreader and uses standard 1.5 V unbuffered DDR3 chips; occasional dust removal from the slot is the only maintenance typically required.

What limits sustained performance on the CL7 1066 MHz timing?

The CAS latency of 7-7-7 at 1066 MHz sets the access-speed ceiling; bandwidth cannot exceed the PC3-8500 rating under continuous load.

How much heat or fan noise does the 1.5 V 2 GB stick add when the laptop runs all day?

Without a heat spreader the 1.5 V DDR3 SODIMM produces minimal extra warmth, so the existing cooling fan does not need to spin faster or louder.
