Targeted DDR3 SO-DIMM kit

This 8 GB kit contains two 4 GB DDR3-1066 SO-DIMM modules built for Acer Aspire 7739Z-4439, 7551G-7606 and 7551-7422 notebooks. It raises the system to the 8 GB maximum those models accept. Buyers with other laptops or desktop boards should not order this kit.

Straightforward notebook installation

Power down, remove the battery, open the memory door and press each 204-pin stick into a slot until the clips latch. The modules are unbuffered, non-ECC and run at 1.5 V with CL7 timing. A mismatch in voltage, pin count or generation will prevent the notebook from booting.

Verify your exact model and slot count

Confirm the Aspire model number matches one of the three listed above. Those systems ship with two slots and a 2 GB or 3 GB factory configuration, so both slots must be filled to reach 8 GB. Do not purchase if your machine uses a different memory generation or has only one slot.
