Hi guys! Please help!

I have this card in my clevo laptop (double mxm slot). I always have reboot or black screen, I've tried  a lot of smbios with no success:

MacPro         3.1/4.1/5.1/6.1                        reboot
iMac             13.1/13.2/14.1/14.2                reboot
iMac             10.1/11.2/11.3/12.1/12.2        black screen
MacbookPro   6.1/8.2/8.3/9.1/10.1               black screen
MacMini        5.1/6.2                                    black screen

Interesting thing is that if I put nvidia card in slot 1 and my amd card in slot 0 both cards are recognized.... Seems to be that nvidia card does not like attached monitors... Please, see my ioreg in attachment!

Any suggestions?

Thanks in advance!

The Nvidia one needs Nvidia Web Drivers to work, the AMD one needs FB patching. That's a pain, and considers use one card only ( I recommend the GTX one for power, AMD one for less pain )

Well, web drivers works just fine when the card is in slot 1, but in slot 0 with attached monitors NOT...

AMD card working fine with my FB, it took me some weeks of googling and trying to do it work!

When I'll make the gtx working, amd goes on selling...but till then, why attached monitors reboot the laptop? Grrrr...

Hi guys! I have some news! I've finally managed to save the ioreg without the image on screen (black screen). I can boot to desktop only with old smbios, with new smbioses it reboots... Please take a look, on 3 connectors there is the same display...
Ideas?
Thank you!
