Alienware x15 R1 Replacement Motherboard

This genuine Dell OEM motherboard serves as a direct system-board replacement for the Alienware x15 R1 laptop. It integrates the processor, memory and graphics into a single assembly matched to the original chassis.

For x15 R1 owners restoring a failed board

Technicians repairing an Alienware x15 R1 can reinstall this board to return the system to factory specification. Builders seeking a modular desktop platform or upgradeable memory slots should look elsewhere because every major component is soldered in place.

Fits the original x15 R1 chassis

Yes, the board is a direct replacement for the original Alienware x15 R1 mainboard and fits the same chassis, heatsink and display connectors.

After installing the board, how do I confirm the RTX 3060 graphics and i7-11800H are running at their rated speeds?

Open Task Manager or GPU-Z to verify the GPU shows as RTX 3060 and the CPU reports a base clock of 2.3GHz with turbo up to 4.6GHz.
