Alienware Graphics Amplifier Running at PCIe 3.0 x1 on Alienware 13 R3 (Kaby Lake)

Hi Everyone,

I'm having problems with my Graphics Amplifier. It seem that it's always running at PCIe 3.0 x1 when I connected it last night. An ASUS GTX 970 Mini is connected in it. The last time I've connected my AGA, I can still run this at full PCIe 3.0 4x.

Here's what I've done so far 

• Uninstall all GPU Drivers
• Uninstall the Graphics Amplifier Service
• Re-install the Graphics Amplifier Service
• Reinstall ONLY the nVIDIA GTX 1050 Ti Driver
• Turn off power and reconnected the AGA

My system are as follows :

• Alienware 13 R3 Core i5 7300HQ
• GTX 1050 Ti 
• BIOS 1.1.9 KBL (I'm thinking to roll this back to BIOS 1.1.8 )

Some suspect items :

• I've installed the latest Intel Chipset Driver, not sure if this does anything?

Anyways, I'm out of options. Has anyone else encountered this issue :( ? 

Thanks.
