What this module adds

This 4GB DDR3 SODIMM upgrades a laptop or all-in-one that uses 204-pin DDR3 memory at 1600MHz. It is a single unbuffered non-ECC stick rated CL11 at 1.5V for standard DDR3 voltage.

Check your system before ordering

Verify that the laptop accepts DDR3 SO-DIMM modules and supports 1600MHz PC3-12800 speed at 1.5V. Confirm the board has a free 204-pin slot and that the maximum capacity per slot allows a 4GB module.

Behaviour under sustained load

The module runs at the JEDEC standard 1.5V with CL11 timings, so it maintains its rated 1600MHz throughput during extended multitasking without requiring higher voltage or aggressive cooling.

Questions about this item

Does the module ship alone or with extra parts such as a screwdriver or thermal pad?

The package contains one 4 GB DDR3 1600 MHz SODIMM module; no tools or additional components are included.

Should I pick the 4 GB stick or look for an 8 GB version of this same part?

This listing is for a single 4 GB module; if your laptop has two slots and supports 8 GB total, adding a second identical stick will give you dual-channel performance.

What does the 1600 MHz rating actually deliver once the RAM is installed?

The module runs at DDR3 1600 (PC3-12800) with CL11 latency at 1.5 V, providing the standard bandwidth and timing for systems that officially support that speed.
