CMS 4GB DDR3 1600MHz SODIMM for Dell Inspiron M5040

This 4GB DDR3 SODIMM module runs at 1600MHz with CL11 timing and 1.5V operation. It uses a 204-pin unbuffered, non-ECC design built with major brand chipsets. The stick is validated for the Dell Inspiron 15 M5040 notebook.

Suits single-slot upgrades on M5040.

This single 4GB stick works for owners adding one module to a free slot or replacing a failed unit. Builders who need matched pairs for dual-channel mode should look elsewhere, as this is a 1-piece kit. Systems limited to 3.5GB recognised memory with a 4GB module will not gain the full capacity.

204-pin DDR3 1600MHz SODIMM form factor decides fit

The module only fits notebooks that accept 204-pin DDR3 SO-DIMMs at 1600MHz. The Dell Inspiron 15 M5040 is the validated platform. Any laptop requiring a different pin count, voltage, or DDR generation will not accept this part.

Questions about this item

What comes in the box and do I need anything else to install it?

The package includes one 4 GB DDR3 1600 MHz SODIMM module; no extra parts are required for installation in a compatible Dell Inspiron 15 M5040 notebook.

Should I pick the single 4 GB stick or a different capacity for my Inspiron 15 M5040?

This listing is a single 4 GB stick; the system supports up to 8 GB total across two sockets, so adding a second identical module gives dual-channel performance and the full 8 GB.

What does the 1600 MHz speed mean once the module is running in my laptop?

The module operates at DDR3-1600 with CL11 timing at 1.5 V, delivering PC3-12800 bandwidth when the memory controller runs at that frequency.
