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.

Întrebări despre acest articol
Does the board ship with the i5-9400H, RAM, Wi-Fi card or heatsink, or must those be sourced separately?
The motherboard includes the soldered Intel Core i5-9400H processor; memory modules, an M.2 2230 Wi-Fi/Bluetooth card and the cooling assembly are not included and must be purchased separately.
Which memory kit should I choose for the four DDR4 SODIMM slots on this Precision 7540 board?
Install four 2666 MHz DDR4 SODIMM modules for a maximum of 128 GB; matching capacity sticks across all four slots gives the best multi-channel performance.
What does the 2.5 GHz base clock of the i5-9400H mean for real workloads on this motherboard?
The six-core processor runs at 2.5 GHz base and can reach 4.3 GHz Turbo, so sustained CAD or rendering tasks hold higher frequencies while the CM246 chipset manages power and thermals.
