Dell Vostro Motherboard X34NW

Genuine Dell OEM system board with on-board Intel Core i3-4005U dual-core CPU at 1.7GHz and discrete Nvidia graphics. Designed as a direct replacement for the Vostro 14 (3446) and Vostro 15 (3546) laptops that originally shipped with discrete graphics. Part number X34NW ensures correct identification. Buyers needing a board for integrated-graphics models cannot use this unit.

OEM Build With Discrete Graphics

Manufactured to Dell specifications for the listed chassis, the board aligns with original mounting points and connector layouts. Discrete Nvidia graphics are integrated on the board, so the cooling assembly and display outputs match the factory design. No separate graphics module is required. Systems without discrete graphics use a different board and are not compatible.

Ready-To-Install CPU Included

The Intel Core i3-4005U processor is permanently mounted, removing the need to source or install a separate CPU. This reduces repair time and eliminates socket compatibility risk. No additional accessories or software are bundled with the motherboard. The board is sold as a standalone component for qualified technicians.

Questions about this item

What Dell part number does this board use and which Vostro models accept it?

Dell part number X34NW fits Vostro 14 3446 and Vostro 15 3546 laptops that shipped with discrete Nvidia graphics.

Which chassis screw pattern and display cable connector does the board require?

The board follows the Vostro 14 3446 and 15 3546 mounting hole layout and uses the same display cable connector as those models.

How is the CPU attached and what step do installers often miss?

The Intel Core i3-4005U is soldered on, so there is no socket installation; the critical step is reapplying thermal paste and securing the heatsink evenly.
