Dell Precision 5750 Motherboard

This genuine Dell OEM system board is built for the Precision 5750 mobile workstation. It integrates a hexa-core Intel Xeon W-10855M processor with discrete Nvidia Quadro RTX 3000 graphics. The board targets professionals replacing a failed mainboard in a laptop configured with the optional discrete GPU.

Check discrete GPU configuration

Verify your Precision 5750 originally shipped with the Quadro RTX 3000 option. This motherboard is not a direct replacement for units relying solely on integrated Intel graphics. Confirm the Dell part number K7XXD matches your service tag documentation before ordering.

Sustained workload behaviour

The on-board Xeon W-10855M runs at a 2.8 GHz base frequency and can reach a 5.1 GHz max turbo frequency under load. The discrete RTX 3000 6 GB GPU delivers consistent graphics compute for professional applications. Thermal management follows the Precision 5750 chassis design to maintain performance during extended sessions.

Questions about this item

Does the K7XXD board ship with the Xeon W-10855M and RTX 3000 already fitted, or must I supply them separately?

The board arrives with the on-board Xeon W-10855M at 2.8 GHz and the discrete Quadro RTX 3000 6 GB already installed; no separate processor or graphics module is required.

How do I confirm my Precision 5750 needs the K7XXD rather than an integrated-graphics board?

Check whether your 5750 originally shipped with the optional Quadro RTX 3000; this K7XXD is only for those discrete-graphics configurations, not for integrated-only units.

What does the 5.1 GHz turbo figure mean for everyday workloads on this board?

The Xeon W-10855M can boost up to 5.1 GHz on active cores, giving short bursts of higher single-thread speed before thermal limits bring clocks back toward the 2.8 GHz base.
