A-Tech 4GB DDR3 1066MHz SODIMM

This A-Tech module provides a 4GB DDR3 1066MHz memory upgrade for compatible laptops, notebooks and all-in-one systems. It matches the Samsung M471B5273BH1-CF8 and M471B5273CH0-CF8 part numbers for direct replacement. The unbuffered, non-ECC stick operates at standard 1.5V voltage with CL7 latency. Buyers needing ECC error correction or registered buffering should select a different module type.

Simple SODIMM installation steps

Installation requires opening the laptop memory compartment, aligning the 204-pin module with the slot key, and pressing down until the retention clips engage. Most systems recognise the memory automatically on boot. Compatibility issues usually arise when the laptop chipset does not support DDR3 1066MHz speeds or the specific 2Rx8 density. Verify the exact model requirements before fitting to avoid a non-posting system.

Check your laptop memory specifications

Confirm your device accepts DDR3 SO-DIMM modules running at 1066MHz (PC3-8500) with 1.5V operation and CL7 timing. Check the maximum supported capacity per slot and the total system limit to ensure this 4GB stick is usable. Ensure the motherboard supports unbuffered, non-ECC memory and the 2Rx8 organisation. Consult the manufacturer manual or support site for the qualified vendor list.

Preguntas sobre este artículo

How can I verify the A-Tech DDR3 module is running at 1066MHz after installation?

Check the memory speed in your BIOS or use a system tool like CPU-Z to confirm it reads DDR3 1066 (PC3-8500) with CL7 timings at 1.5V.

What comes with the 4GB SODIMM and do I need any extra parts?

The box contains one 4GB 204-pin DDR3 SO-DIMM module only; no tools, screws, or additional cables are required for laptop installation.

Which capacity should I choose if my laptop has two slots and supports 8GB total?

Buy two of these 4GB modules to reach the 8GB maximum using both slots.
