Alienware 17 - Latest driver for GTX1080

Hi,

I've just migrated to a new laptop (Alienware 17 (1Y1DPF2) with a mobile GeForce GTX 1080 graphics card). The out of the box driver for the GTX 1080 is too old to support NVidia CUDA programming.

I've tried to get later drivers a couple of ways:

(1) via the Windows 10 device manager.  This finds a driver from September but it also does not support CUDA properly (you cannot debug CUDA code using NVidia's NSight application).

(2) via Dell's website.  The latest driver for the machine does not recognise the graphics card. Inspecting the driver package shows that it includes the 1070 card but not 1080 - i.e. Dell are offering me the wrong download for my machine ID)

(3) via Nvidia's website.  The mobile drivers (376.09) do not recognise the graphics card.

In the end I have searched the drivers from Nvidia (376.09) and found an Acer configuration GTX1080 which I installed manually by modifying the hardware ID to match the GTX1080 on the Alienware 17 (PCI\VEN_10DE&DEV_1BE0&SUBSYS_07C21028).  This partially solved the problem, but there are still problems with the driver for CUDA - some instability is encountered.  It's fine for gaming etc incidentally.

Does anyone have a solution?  Why are Dell not providing the latest NVidia drivers for this card?
