I just bough the Radeon HD 6670 to crossfire it with the A8-3850 integrated graphics. As it is pretty complicated to setup the crossfire and AMD doesn't give you any advice I've watched some videos and read a few tutorials so I can make it right.
Here's what I've done:
- With the 6670 not plugged in I've setup BIOS to use the primary display graphics ONBOARD
- Installed the latest AMD Catalyst (12.8)
- Plugged in the discreet card and put monitor cable from onbord DVI to the dedicated DVI
- Enabled in Catalys the AMD Dual Graphics option (there is no Crossfire option only this one)
I think I managed to setup the crossfire properly but it seems it doesn't work. I'm saying this because the Windows 7 benchmark index haven't changed at all. I've got same 6.8 mark for using the dedicated HD 6670 alone or both APU and discreet card in crossfire. Also in-game FPS are the same.
Do you have any idea of how to solve this issue or any other way to check if the crossfire is working.
