Dell Inspiron 15 N5040 upgrade kit

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules built for the Dell Inspiron 15 N5040 notebook. The 204-pin sticks run at 1333 MHz with CL7 latency and 1.5 V operation. Unbuffered, non-ECC chips are arranged in a 2Rx8 configuration using major-brand components.

Sustained workload behaviour

Dual-channel pairing lets the memory controller interleave data across both modules during long sessions. CL7 timing keeps row-access delays low when the system holds many browser tabs or compiles code. The 1.5 V spec matches the platform voltage so thermal output stays consistent without extra cooling.

Replaces the factory 4 GB limit

The notebook ships with a 4 GB ceiling and two slots that must be populated in pairs. This kit fills both sockets to reach the 8 GB maximum the board recognises. A 64-bit operating system is required to address the full capacity; 32-bit environments will see only 3.5 GB. Buyers needing more than 8 GB cannot use this platform.

Questions about this item

How much power does the 1.5V DDR3 kit draw when the laptop runs all day?

Each module operates at 1.5V, the standard voltage for DDR3 SO-DIMMs, so power draw stays within the Dell Inspiron 15 N5040's normal memory budget.

What must the notebook already have to install this 204-pin DDR3 kit?

The Inspiron 15 N5040 needs two free SO-DIMM slots and a 64-bit operating system to use the full 8GB capacity.

Will this CL7 1333 MHz memory work with the original 10600-speed modules I might keep?

The kit runs at DDR3-1333 CL7; mixing with slower CL9 sticks forces the system to run at the lower common speed and looser timings.
