Genuine Dell Latitude 3340 system board

This genuine Dell OEM motherboard integrates an Intel Core i3-1215U processor and 8GB of memory onto a single system board. It serves as a direct replacement for the mainboard in compatible Dell Latitude 3340 and Latitude 3340 2-in-1 laptops. The board arrives as a complete unit with the CPU and RAM already installed.

Repair upgrade for failed Latitude 3340 boards

The part replaces a damaged or faulty original motherboard in the listed Latitude 3340 models. The jump is worth it when the existing board no longer posts, shows component-level failure, or when a full board swap is faster than component-level repair. The on-board Intel Core i3-1215U 6 core CPU reaches a maximum turbo speed of 4.4GHz for restored system performance.

Drop-in fit for Latitude 3340 chassis

The board matches the exact mounting points, connector layout and thermal interface of the original Latitude 3340 design. It requires the correct laptop chassis, display assembly, battery and bottom cover from the same model family. No separate CPU cooler, memory modules or socket installation are needed because the processor and 8GB RAM are permanently integrated.

Questions about this item

What laptop chassis does the DMV8Y motherboard fit?

The DMV8Y board is built for the Dell Latitude 3340 and Latitude 3340 2-in-1 chassis. It aligns with the mounting points and port cut-outs of those models only.

Which step is often missed when installing the i3-1215U system board?

After seating the board, the CPU heat-sink must be torqued in the numbered sequence printed on the frame before any cables are reconnected; skipping the sequence creates uneven pressure on the 1215U die.

What component will need replacement first on this board?

The on-board 8 GB memory is soldered and cannot be upgraded; if capacity becomes limiting the whole DMV8Y board must be swapped.
