Dell Inspiron 15 (3558) memory upgrade

This 4 GB DDR3L SODIMM is built specifically for the Dell Inspiron 15 (3558). It installs in a 204-pin slot and runs at 1.35 V, matching the voltage the notebook expects. The module is unbuffered and non-ECC, so it works with the standard consumer memory controller in that system.

Sustained load behaviour

CL11 timing at 1600 MHz keeps latency predictable during long sessions. The major-brand chipset and 1Rx8 organisation deliver stable throughput without the errors that generic modules can introduce. Operation stays consistent because the stick is validated for the exact platform rather than tested only at JEDEC defaults.

Deciding specification

The 4 GB capacity is the critical figure; the Inspiron 15 (3558) supports a maximum of 8 GB across two sockets. Buyers who want more storage or need to fill both slots for dual-channel bandwidth will need a second module. A 64-bit operating system is required to address the full amount.

Questions about this item

How much heat or noise does the 1.35 V DDR3L SODIMM generate when the laptop runs all day?

The module operates at 1.35 V without a heat spreader, so it adds negligible heat and makes no audible noise inside the Dell Inspiron 15 (3558).

What must my Dell Inspiron 15 (3558) already have for this 204-pin DDR3L 1600 CL11 stick to work?

The laptop needs a free 204-pin SODIMM slot, a 64-bit operating system, and support for DDR3L 1.35 V unbuffered non-ECC memory.

Will this 4 GB DDR3L 1600 module run correctly alongside the original 4 GB stick in the second slot?

Yes, the system supports up to 8 GB across two sockets, so adding this 1Rx8 CL11 module to the existing stick will give 8 GB total at 1600 MHz.
