Precision 7540 Xeon Motherboard

This genuine Dell OEM system board is built for the Precision 7540 laptop. It arrives with the Intel Xeon E-2276M hex-core processor already soldered in place at 2.8 GHz. The part number DKGFW confirms exact fitment for that chassis. Buyers needing a different socket or a removable CPU cannot use this board.

On-board Xeon E-2276M limits

Because the CPU is permanently mounted, the motherboard cannot be upgraded to another processor or core count. The fixed 2.8 GHz base frequency and six-core design set the performance ceiling for the whole system. No BIOS update or hardware change can alter that constraint. Repairs therefore replace the entire board rather than the chip alone.

DKGFW part-number match

The DKGFW part number is the single specification that decides whether this is the correct replacement. It must match the original board sticker on the Precision 7540 exactly. A different Dell part number, even for a similar model, indicates a different layout or firmware and will not fit.

Questions about this item

Which motherboard version should I choose for a Precision 7540 that needs the Xeon E-2276M?

The DKGFW board includes the Xeon E-2276M soldered on, so there is no separate CPU version to select; it arrives as a single matched unit for the 7540 chassis.

What does the 2.8 GHz figure mean once the board is installed in a Precision 7540?

The Xeon E-2276M runs at a 2.8 GHz base clock across its six cores, providing that frequency under sustained loads when the laptop cooling can maintain it.

What interface does the DKGFW motherboard use and what does it cap in practice?

The board connects to the Precision 7540 through its proprietary system-board interface, which limits upgrades to components the original laptop design supports.
