4 GB SO-DIMM DDR3L 1600 for Laptops

This 4 GB module uses the SO-DIMM form factor and runs at 1600 MT/s with CL11 latency. It operates at 1.35 V and is unbuffered without ECC. Suitable for compatible laptop memory slots.

Who This Suits and Who Should Look Elsewhere

Suitable for owners of laptops that accept DDR3L SO-DIMM modules at this speed and voltage. Not for buyers who need a higher capacity module, registered memory, ECC support, or a different memory generation.

Deciding Specification — DDR3L 1.35 V

The 1.35 V operating voltage identifies this as a DDR3L part, which is the single specification that determines whether it fits the slot and works with the system memory controller.

Questions about this item

How do I install the CT51264BF160B SO-DIMM and which step do people often miss?

Align the notch on the module with the slot key, insert at an angle, then press down firmly until both side clips click; the step people miss is pushing until both clips engage fully.

What maintenance or replacement will the CT51264BF160B need later?

No scheduled maintenance is required; if errors appear, run a memory diagnostic and replace the module if it fails testing.

What limit appears first on the CT51264BF160B during sustained heavy use?

The 4 GB capacity is the first bottleneck; once the workload exceeds available memory the system will swap to storage, slowing performance.
