I have an MSI 880GMA-E45 motherboard, having an onboard HD 4250
My dedicated graphics card is a Sapphire HD 6850

I know the HD 4250 cannot mine, but my the problem is this:

When I set the HD 4250 as the primary graphics card on BIOS, I could use it as the output card while the HD 6850 could mine in the background.

The problem is that when I run Sapphire Trixx it reads the HD 4250 instead of the 6850, therefore preventing me from adjusting the clocks of the 6850.

Is there a way to rectify this? Or is there any other program that would let me adjust the clocks of the 6850 so I could increase the core clock to 960 and decrease the memory clock to 344?

Trying to use the IGP so I can mine at full power without the desktop stuttering.

Thanks
