A-Tech 4GB DDR3L 1600 SODIMM laptop RAM Samsung M471B5173BH0-YK0 CB0 DB0 EB0 QH0 PC3L-12800 1Rx8

4 GB DDR3L SODIMM for laptop upgrades

This A-Tech module supplies four gigabytes of DDR3L memory at 1600 MHz with CL11 latency. It uses the 204-pin SO-DIMM form factor and runs at 1.35 volts. The stick is unbuffered, non-ECC and built as a direct replacement for several Samsung part numbers. It targets owners of compatible notebooks or all-in-one systems who need a straightforward capacity increase.

Suits DDR3L 1.35 V platforms needing a single 4 GB

The module fits laptops that accept DDR3L SO-DIMMs at 1600 MHz and 1.35 V. It will not work in systems that require 1.5 V DDR3, registered or ECC memory, or modules larger than four gigabytes per slot. Buyers whose machines need higher density per slot, a different voltage or a faster data rate should look at other options.

1.35 V low-voltage DDR3L specification

The defining specification is the 1.35 V operating voltage that marks this memory as DDR3L rather than standard DDR3. A system designed for 1.5 V DDR3 may not recognise or stabilise with this module. Confirm that the laptop explicitly supports DDR3L 1.35 V before ordering.
