2GB DDR3 SO-DIMM for Acer Aspire One

This 2GB DDR3 1066MHz SO-DIMM module is built for specific Acer Aspire One netbooks including the D255E series. It targets owners of those machines who need a direct replacement or a single-slot upgrade. The memory runs at PC3-8500 speed with CL7 latency and 1.5V operation.

204-pin unbuffered design fits factory slot

The stick uses a standard 204-pin SO-DIMM edge connector and unbuffered, non-ECC architecture that matches the original factory specification. Major-brand DRAM chips are used without a heat spreader, keeping the low profile required by the netbook's tight chassis. One module fills the single available socket.

Single-module kit with lifetime warranty

The package contains one 2GB memory stick backed by Computer Memory Solutions' limited lifetime warranty when purchased directly. No additional cables, tools or software are included. Buyers needing more than 2GB total capacity or dual-channel configurations cannot use this module alone.
