Acer Aspire DDR3 SO-DIMM upgrade

This 4 GB DDR3 module is built to upgrade Acer Aspire models 5749-6863, 7741Z-4643 and 5749Z-4449. It installs in a single 204-pin SO-DIMM slot and runs at 1.5 V without ECC or buffering. The stick uses major-brand chips and carries a limited lifetime warranty from the manufacturer.

Suitable for single-slot top-up, not full 8 GB

Owners wanting to add 4 GB to an empty slot or replace a failed stick will find this a direct match. Systems already populated with two modules or users targeting the 8 GB maximum should look at a 2 x 4 GB kit instead.

Speed rating DDR3 1333 (PC3 10600)

The module is rated for 1333 MT/s with CL7 7-7-7 timings. If the laptop memory controller only supports 1066 MT/s, the part will downclock automatically, but it will not run faster than 1333 MT/s.

Questions about this item

Will this 204-pin DDR3 1333 MHz SO-DIMM run at its rated speed alongside the existing 1066 MHz memory in my Acer Aspire 5749?

The module is rated for 1333 MHz CL7 at 1.5 V; when paired with 1066 MHz sticks the system will downclock both to 1066 MHz and use the slower timings.

How can I confirm the stick is detected at 4 GB and running in dual-channel mode after installation?

Open Task Manager’s Performance tab or run CPU-Z; both should show 4 GB total and dual-channel operation if the second slot is populated with a matching module.

Does the package include only the single 4 GB SO-DIMM or are tools and a second stick also supplied?

The box contains one 4 GB 204-pin DDR3 SO-DIMM; no screwdriver, no second module and no heat spreader are included.
