Kit specifics and fit

This 8 GB kit contains two 4 GB DDR3 SODIMM modules rated at 1066 MHz with CL7 timing. It is built for Acer Aspire 5742-332G32Mnkk and As5552-N833G50Mnkk notebooks that use 204-pin unbuffered memory.

Who this suits and who it does not

Owners of the listed Acer models can use this pair to reach the 8 GB maximum supported by those systems. Buyers with laptops that require ECC or registered DIMMs, or that have only a single memory slot, cannot use this kit.

The specification that decides compatibility

The modules run at 1.5 V with a 2Rx8 organisation and 7-7-7 timings; the notebook must accept DDR3 PC3-8500 SODIMMs at this voltage and rank configuration for the upgrade to work.

Questions about this item

How do I install these 204-pin DDR3 SODIMM modules in my Acer Aspire 5742, and what step is commonly missed?

Power off, unplug, and remove the battery. Open the memory door, align the notch on each 204-pin stick with the slot key, insert at an angle, then press down firmly until both side clips click. The step often missed is pressing evenly on both ends until the clips fully engage.

What maintenance or replacement will this 8GB kit need during its service life?

No scheduled maintenance is required. The modules are unbuffered, non-ECC, and have no heat spreader. Keep the laptop vents clear of dust so the memory stays within its 1.5 V operating envelope. Replacement is only needed if a module fails or you upgrade beyond the 8 GB maximum supported by the 5742 platform.

What limit appears first when the memory runs at 1066 MHz under sustained load?

The platform's two-slot, 8 GB maximum capacity is reached with this 2x4 GB kit, so no further memory can be added. Thermal limits of the laptop chassis and the fixed 1.5 V supply constrain sustained throughput before any memory-intrinsic ceiling is hit.
