4 GB DDR3 1066 SO-DIMM for Acer Aspire laptops

This 4 GB module uses 204-pin DDR3 SO-DIMM form factor running at 1066 MHz with CL7 timing. It operates at 1.5 V and is unbuffered non-ECC memory. The stick is built with major-brand chips in a 2Rx8 configuration and carries a limited lifetime warranty from the manufacturer.

Replaces or adds to factory memory in three Acer

The upgrade targets Aspire AS5560G-Sb468, AS5733-6437 and AS7560-Sb416 systems that ship with two slots and a 8 GB maximum. Adding this module fills one slot and raises capacity toward the 8 GB ceiling. The jump is worthwhile when the current configuration leaves a slot empty or runs a smaller module that limits multitasking headroom.

DDR3 1066 interface caps bandwidth at PC3 8500

The memory standard tops out at 1066 MHz, so throughput cannot exceed the PC3 8500 rating regardless of tighter timings. Two slots in the supported laptops mean dual-channel operation is possible only with a matched pair. Systems already populated with faster DDR3 will down-clock to 1066 MHz when this module is installed.

Questions about this item

Does the 204-pin SO-DIMM fit the two memory slots in my Acer Aspire AS5560G-Sb468?

Yes, this 204-pin DDR3 SO-DIMM matches the two slots in the Aspire AS5560G-Sb468, AS5733-6437 and AS7560-Sb416.

What is the correct way to seat the module so the side clips engage?

Align the notch on the gold edge with the key in the slot, push the module in straight until the edge is fully seated, then press down until both side clips snap into the notches.

Will this 4 GB stick ever need a firmware update or battery replacement?

No, the module has no firmware or battery; it only requires replacement if you later want more than 8 GB total system memory.
