Hello,
I've been tryng all day to get my Asus M3N78 Pro mobo recognise an brand new xfx HD6850 pcie 2.1 graphics card. I have flashed the latest version of the Bios fom the ASUS site, but in the end have had to go back to a 5450 GPU. Has anyone got a 2.1 spec GPU running on a M3N78 Pro or can suggest where i've gone wrong?

Thanks for the reply
- No signal to monitor from 6850
- PC boots fine, but need to use HDMI from mobo to monitor
- just checked PowerColor website and yes, the 5450 2GB card i have is PCIe 2.1 - so mobo must support 2.1 :-)
- Yes, 6 pin power cable was attached to 6850 - loud fan going full bore!
- Couldn't instal drivers - no compatible device found...
- PSU is a Corsair VX550W

Thinking i might try again but run 'Driver Sweeper' before i instal the 6850 - otherwise i think the 6850 is DOA

Any other suggestion appreciated! :-)

Unistalled all AMD software (had to repair it before uninstal), reboot, removed card, reboot, ran driver sweeper, reboot, installed card, reboot, installed AMD Catalyst and all is well now finally - thanks for the help! :-)
