Genuine Dell Precision 3550 System Board

This genuine Dell OEM motherboard serves as a direct replacement for the Precision 3550 mobile workstation. It integrates an Intel Core i7-10510U processor and discrete Nvidia Quadro P520 graphics onto a single board. Technicians and owners use it to restore full system function after a mainboard failure.

Capacity and Headroom

The on-board quad-core CPU runs at a 1.7 GHz base clock with a maximum turbo frequency of 4.9 GHz. This provides solid performance for professional applications and moderate multi-tasking workloads. The discrete Quadro P520 GPU adds dedicated graphics memory for CAD and 3D tasks. Heavy sustained loads will hit thermal and power limits inherent to the laptop chassis.

Interface and Form-Factor Constraints

The board uses a proprietary Dell layout designed exclusively for the Precision 3550 chassis. It cannot be mounted in standard desktop cases or other laptop models. All I/O, cooling mounting points and connector placement are fixed to that specific enclosure. Buyers must verify their exact service tag before purchase.

How can I verify the on-board i7-10510U and Quadro P520 are detected correctly after installation?

Enter the system BIOS or UEFI on first boot; the main information screen should show an Intel Core i7-10510U processor with a maximum turbo frequency of 4.9 GHz and an Nvidia Quadro P520 discrete graphics device.

Does the board ship with the CPU and graphics already soldered on, or do I need to source them separately?
