Genuine Dell Precision 3520 system board

This genuine Dell OEM motherboard integrates an Intel Core i7-7820HQ quad-core processor running at 2.9GHz. It is built specifically for the Precision 15 3520 laptop chassis. The board includes on-board Nvidia Quadro M620 graphics for professional visual workloads. Buyers who need a discrete GPU upgrade path or a different CPU socket should look elsewhere.

Bundled processor and graphics

The on-board i7-7820HQ and Quadro M620 are soldered to the board, so the purchase replaces both the CPU and GPU in one step. No separate processor or graphics card is required or supported. This eliminates version-mismatch risk but also means neither component can be upgraded later. Builders who want to choose their own CPU or GPU combination cannot use this board.

Direct laptop board swap

Installation is a straight motherboard swap inside the Precision 15 3520; the DCKVD part number matches the service manual. Common issues include forgetting to transfer the original thermal-pad layout, missing a display-cable connector, or failing to update the BIOS after the swap. Technicians without laptop disassembly experience often damage fragile ribbon cables during reassembly.

Questions about this item

Will the on-board Intel Core i7-7820HQ CPU ever need to be replaced separately from the motherboard?

The i7-7820HQ is soldered directly to the board, so the processor cannot be swapped out on its own; if the CPU fails the whole motherboard must be replaced.

What thermal limit appears first when the Nvidia Quadro M620 runs at full load for hours?

The M620 shares the laptop’s single heat-pipe assembly, so GPU temperature hits its throttle point before the CPU does, reducing clocks to protect the chip.

How loud does the cooling fan get when the Precision 3520 motherboard runs all day under heavy load?

With both the 2.9 GHz quad-core CPU and the M620 active, the fan spins to maximum speed and produces a clearly audible whine that stays constant until the workload drops.
