Product identity

This 8GB DDR4 SO-DIMM module is built for Samsung Series 7 notebooks including the NP740U3L, NP740U3M, NP740U5L and NP740U5M. It delivers a single 8GB stick rated at 2400 MHz with CL17 timings for owners who need a direct replacement or a capacity increase.

Build fit

The stick uses the standard 260-pin SO-DIMM form factor and runs at 1.2V, so it slots into the existing memory socket without an adapter or voltage change. The notebook platform supports up to 32GB across two sockets, leaving the second slot free for a matching module if more capacity is required later.

Thermals and power

With no heat spreader and a low 1.2V operating voltage, the module adds minimal thermal load inside the thin chassis. Unbuffered non-ECC operation keeps power draw modest during typical workloads, and the lack of active cooling means the upgrade does not introduce any fan noise.

Questions about this item

What is the CAS latency that limits sustained memory throughput?

The module runs at CL17 with 17-17-17 timings, which sets the baseline latency for continuous read and write operations.

How much heat and power does the stick produce during all-day workloads?

It operates at 1.2 V without a heat spreader, so power draw and thermal output stay low enough for thin ultrabook chassis.

Which Samsung notebook models must I already own for this upgrade to work?

It is validated for Samsung Series 7 NP740U3L, NP740U3M, NP740U5L and NP740U5M including the listed regional sub-models.
