Product Identity

This A-Tech module is a 4 GB DDR3L SODIMM built as a compatible replacement for the Crucial CT4G3S160BJM part. It targets owners of laptops, notebooks and all-in-one systems that require a single 204-pin unbuffered stick running at 1600 MHz with CL11 timing.

Fit and Limits

The stick suits machines specified for 1.35 V DDR3L memory in a 204-pin SO-DIMM slot. Buyers whose systems demand 1.5 V DDR3, ECC or registered modules, or a different pin count should look elsewhere. The 4 GB capacity also means this is not the right part for anyone needing a larger single-module upgrade.

Deciding Specification

The critical figure is the 1.35 V operating voltage that defines the DDR3L standard. Only systems explicitly rated for DDR3L or dual-voltage DDR3/DDR3L will run this module correctly; a platform locked to 1.5 V DDR3 may not boot or may default to a lower speed.

Questions about this item

Does this module need a 204-pin DDR3 SO-DIMM slot to install?

Yes, it is a 204-pin DDR3 SO-DIMM and requires a matching laptop slot.

Will it run at 1.35 V alongside 1.5 V DDR3 sticks already in my laptop?

The module operates at 1.35 V; if the system supports DDR3L it will down-volt automatically, otherwise it may not be compatible.

How do I confirm the stick is running at 1600 MHz CL11 after fitting it?

Check the memory speed and CAS latency in BIOS or a tool such as CPU-Z; they should show 1600 MHz and CL11.
