  • Single 4 GB 204-pin SODIMM installs in one slot

Targeted DDR3L upgrade

This 4 GB SODIMM runs at 1600 MHz with CL11 timing and 1.35 V voltage. The unbuffered, non-ECC module uses a 204-pin layout and major-brand chips. Computer Memory Solutions guarantees compatibility with the Dell Inspiron 15 3520 laptop.

Replaces slower or smaller DDR3L sticks

Swapping an existing 1600 MHz module for this kit keeps the same speed while adding capacity. The jump is worth it when the system currently runs a single 2 GB or 4 GB stick and the workload demands more headroom for multitasking.

Suits owners of the Inspiron 15 3520

Builders needing ECC, registered DIMMs, higher frequencies or voltages beyond 1.35 V should look elsewhere. The single 4 GB stick also leaves one slot free on the two-slot board, but buyers who want the full 8 GB maximum in one purchase must add a second module.

Questions about this item

Does this 204-pin SODIMM fit the memory slot in a Dell Inspiron 15 3520?

Yes — the module is a 204-pin DDR3L SODIMM and the system specific listing confirms compatibility with the Inspiron 15 (3520).

What is the correct way to seat this DDR3L SODIMM, and what step do people often miss?

Align the notch on the gold edge with the key in the slot, insert at an angle until the pins are hidden, then press down evenly until both side clips snap into the notches on the module.

Will this 1.35 V DDR3L module need a voltage adjustment or replacement if I later upgrade the BIOS?

The stick runs at the standard 1.35 V for DDR3L and is unbuffered non-ECC; no voltage change is required and the module itself has no replaceable parts.
