So I've run into an issue regarding crossfire and after extensive searches it has come to my attention that I am the only one with the issue.
I've recently purchased a new MSI R9 390x to pair with my other MSI R9 390x. I am aware of the power draw and a have decent enough power supply to run it.
So, my issue is that when I installed them both, I received no errors no BSOD's nothing. It goes through post and just sits there at the windows logo with the spinning dots. after about an hour and a half it will BSOD and rerun through the booting process. I have tried to fix this multiple times by uninstalling the drivers with DDU and reinstalling them. Still Nada. Fresh installs of windows. Nada, Same thing. I have switched the card around. They work fine individually and they work fine in both PCI slots.
BUT. By sheer mistake I accidentally installed a windows 10 32bit OS and to my surprise booted first time no hassle. I could run crossfire and everything. Installed drivers just fine and rebooted just fine. So thinking maybe it was a fluke, I redownloaded then reinstalled windows 10 64bit and guess what. STILL STUCK AT WINDOWS LOGO! So I reinstalled 32bit back on there and whala!! It worked like a charm. Sad thing is you cant run most games on a 32 bit system, and you can't have more than 4gb of ram either so its not a very reliable setup.
So in conclusion, anyone got a fix for this? Maybe toss me a bone and tell me whats causing it?
