4GB DDR3L laptop module

This 4GB DDR3L SO-DIMM runs at 1600MHz with CL11 timings and 1.35V operation. It suits owners of older notebooks that require low-voltage DDR3 memory for a straightforward capacity increase.

Low voltage thermals and power

The 1.35V rating reduces heat output compared to standard 1.5V DDR3, helping keep internal temperatures modest during typical workloads. Unbuffered, non-ECC design adds no extra controller overhead, so power draw stays minimal in everyday use.

Single-rank 1Rx8 organisation

The module uses a single-rank 1Rx8 layout, which determines how the memory controller addresses the chips. Buyers needing dual-rank density or ECC error correction should look elsewhere, as this stick provides neither.

Questions about this item

How do I install this 204-pin SO-DIMM and which step do people often get wrong?

Align the notch with the slot key, insert at an angle, then press down firmly until both side clips snap shut; the step often missed is pushing hard enough to engage both clips.

What maintenance or replacement will this 1.35V DDR3L module need later?

No routine maintenance is required; replacement is only necessary if the module fails or if the system is upgraded to a platform that uses a newer memory generation.

What limit appears first when this CL11 1600MHz kit runs under sustained load?

The CAS latency of CL11 at 1600MHz sets the timing boundary; sustained workloads will hit this latency limit before any thermal throttle on standard laptop modules.
