SKU CH-36GV-CC39R

Genuine Dell Precision 3520 replacement motherboard with on-board Intel Core i7-6820HQ quad-core CPU at 2.7 GHz and discrete Nvidia Quadro M620 graphics

  • Genuine Dell OEM replacement ensures exact fit for Precision 3520
  • On-board Intel Core i7-6820HQ quad core CPU at 2.7GHz base frequency
  • Turbo boost up to 3.6GHz delivers extra performance when needed
  • Discrete Nvidia Quadro M620 graphics supports professional visual workloads
  • Dell part number 0C220 confirms correct model for discrete-graphics systems

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.

商品問答

Should I choose this 0C220 board or an integrated-graphics version for my Precision 3520?

Pick the 0C220 board only if your Precision 3520 originally shipped with discrete Nvidia Quadro graphics; it will not fit UMA models.

What does the 2.7 GHz base clock with 3.6 GHz turbo mean for daily workloads?

The on-board i7-6820HQ runs at 2.7 GHz base and can boost to 3.6 GHz, giving strong single-thread speed for CAD and compile tasks.

How does the Quadro M620 graphics connect to the system and what does that limit?

The M620 is soldered to the motherboard, so GPU performance is fixed and cannot be upgraded later.
