Dell Precision 7540 i5-9400H 2.5 GHz Motherboard PPNV7

Dell Precision 7540 Motherboard i5-9400H

This replacement motherboard is built for the Dell Precision 7540 mobile workstation and comes with an Intel Core i5-9400H processor soldered on board. It targets technicians and IT departments restoring a unit to factory specification or upgrading from a lower-tier board. The CM246 chipset and hexa-core CPU suit CAD, rendering and virtualization workloads on this platform.

Check MXM GPU and cooler clearance before ordering

Verify that your existing MXM graphics module matches the board's dedicated GPU support and that the heatsink assembly aligns with the processor and chipset mounting points. Confirm the chassis can accommodate the 13.5 × 9.6 × .8 inch board dimensions and that the 2666 MHz DDR4 SODIMM modules you plan to install are compatible with the four available slots. Ensure the M.2 2280 and 2230 keying matches your NVMe SSD and Wi-Fi card.

Thermals noise and power draw in normal use

The Intel Core i5-9400H operates at a 2.5 GHz base clock with a 4.3 GHz turbo ceiling, so sustained loads will raise package temperature and fan speed accordingly. Integrated Intel UHD Graphics 630 handles light output while the discrete MXM GPU drives heavier visual tasks, each adding to the thermal load. The 1.65 lb board distributes heat across the CM246 chipset and CPU area, requiring the original vapor-chamber cooler to maintain stable operation.
