DELL Precision 3520 Motherboard i7-6820HQ 2.7GHz Quadro M620 0C220

Genuine Dell Precision 3520 Motherboard

This genuine Dell OEM system board is a direct replacement for the Precision 3520 laptop when it was originally configured with discrete graphics. The board arrives with an Intel Core i7-6820HQ quad core processor soldered in place, running at a base frequency of 2.7GHz and reaching a maximum turbo frequency of 3.6GHz. Discrete Nvidia Quadro M620 graphics are also integrated onto the board.

Discrete graphics compatibility constraint

This motherboard only fits Precision 3520 units that shipped with the discrete Quadro M620 GPU; it will not work in models that rely on integrated Intel UMA graphics. The part number 0C220 identifies this specific discrete-graphics variant, so the board cannot be swapped into a system built for the integrated-graphics version. Verify the original configuration before ordering to avoid a mismatch.

Check original laptop graphics type

Confirm that your Precision 3520 currently uses discrete graphics rather than the integrated Intel UMA option, as the two motherboard types are not interchangeable. Locate the service tag or existing motherboard part number and match it to 0C220 to ensure the correct fit. If the original system uses integrated graphics, this board will not be compatible.
