...SmartGart And setting AGP Speed.

[Infernix]

So under SmartGart in catalust control center with a ati card (Im use x850 pro)
I trying setting my agp speed to 8x,
It ask me to restart my computer which I do then my computer reload I look at it again and agp is off as usual.
I flashed motherboards bios and I have uninstalled the drivers and reinstalled them.

Yet still I am unable to set it to agp 8x in which my motherboard does support.
I cannot set it in Bios because it removed to option and switches to vlink 8x support or somthing like that.

Anyone else ever had or have that problem and know a way to solve the problem?
