A-Tech 4GB DDR3 1333MHz PC3-10600 204-Pin SODIMM 1Rx8 Samsung M471B5173BH0-CH9 M471B5173DB0-CH9 laptop RAM

Laptop DDR3 4 GB module

This A-Tech SODIMM adds 4 GB of DDR3 memory at 1333 MHz to a compatible notebook or all-in-one system. It matches the Samsung M471B5173BH0-CH9 and M471B5173DB0-CH9 part numbers for direct replacement. The single-rank 1Rx8 organisation and CL9 latency suit everyday multitasking workloads. Builders should confirm their platform supports DDR3 before ordering.

204-pin unbuffered non-ECC stick

The module uses the standard 204-pin SO-DIMM form factor and runs at the DDR3 default voltage of 1.50 V. Unbuffered, non-ECC construction means it drops into ordinary consumer laptop slots without registration or error-correction overhead. Gold-edge contacts resist oxidation during repeated upgrades. No heatsink or tall profile is present, so it fits tight chassis clearance.

Lifetime warranty with US-based support

A-Tech backs every module with a lifetime warranty and provides complimentary United States technical support before, during and after purchase. Each stick undergoes quality-assurance testing to verify reliable operation. The warranty and support terms apply directly to this 4 GB DDR3 1333 MHz SODIMM. No additional software, cables or adapters are bundled.
