Alienware M11x R2 motherboard
This genuine Dell motherboard carries part number 1KK46 and is built for the Alienware M11x R2 notebook. It arrives new and includes an on-board Intel Core i5-520UM processor, so no separate CPU installation is required.
Integrated i5-520UM processor
The soldered i5-520UM runs at 1.066 GHz base frequency and can reach 1.866 GHz max turbo frequency. On-board Nvidia graphics are also integrated, removing the need for a discrete graphics module in this platform.
11-inch ultraportable gaming scope
The board fits the compact 11-inch chassis and supports the original M11x R2 thermal and power design. It does not serve larger Alienware models or desktop systems, and it cannot accept a different processor or graphics upgrade.

Questions about this item
Will the soldered i5-520UM processor need replacement later?
The i5-520UM is soldered to the board and cannot be replaced separately; only a full motherboard swap would change the CPU.
What thermal limit appears first under sustained load?
The on-board Nvidia graphics and 1.066 GHz processor share the same cooling, so GPU and CPU temperatures rise together until the system throttles.
How much fan noise and heat should I expect during all-day use?
The single-fan design cools both the i5-520UM and the discrete GPU, so sustained loads push fan speed higher and surface temperatures up.
