System-specific DDR3 upgrade kit

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules rated at 1066 MHz with CL7 timing. It is built for Acer Aspire models 4250-BZ637, 5253-BZ659 and 5253-BZ660 that accept DDR3-1066 memory.

Straightforward laptop installation

The 204-pin unbuffered sticks install in the two SO-DIMM slots inside the notebook. No heat spreader is fitted, so clearance is minimal; the only common issue is seating both modules firmly until the retention clips click.

Verify your exact Aspire model

Check the service tag for AS4250-BZ637, AS5253-BZ659 or AS5253-BZ660 before ordering. These systems ship with 2 GB or 3 GB and support a maximum of 8 GB across two slots, so this kit fills the board completely.
