4GB DDR3 SO-DIMM for Acer Aspire laptops

This 4 GB DDR3-1066 module is built for the Acer Aspire AS7250-0209, AS5750-6461 and AS5733Z-4633 series. It also covers the AS7750G-9810, AS7750G-6857 and AS7750G-6645 models. The unbuffered, non-ECC stick suits owners who need a direct replacement or a single-slot upgrade for these systems.

Single 204-pin stick with CL7 timing

The kit contains one 204-pin SO-DIMM rated at PC3-8500 with 7-7-7 latency at 1.5 V. Major-brand chips are used and the module carries a 2Rx8 organisation. No heat spreader is fitted, keeping the profile low for tight notebook chassis.

Straightforward notebook installation

Power down, remove the battery if accessible, then open the memory door and insert the module until the side clips lock. The 204-pin key prevents mis-insertion. Buyers who need more than 4 GB or a second module for dual-channel operation should verify their model’s maximum supported capacity and slot count before ordering.

Questions about this item

Will the 2Rx8 rank configuration on this DDR3 SO-DIMM need any special handling when I install it in my Acer Aspire?

The 2Rx8 organisation is standard for DDR3 laptop memory; seat the 204-pin module firmly until the clips click and the system will recognise the 4 GB automatically.

What is the first limit I will hit if I run this memory at full 1066 MHz continuously?

The CL7 timing at 1.5 V is the rated operating point; sustained load simply stays within that specification without additional throttling.

How much heat does this unbuffered DDR3 stick produce during all-day use without a heat spreader?

Standard DDR3 SO-DIMMs at 1.5 V run cool enough for passive laptop airflow; no extra cooling is required for continuous operation.
