Hi guys, have any of you all gotten 3+ gpu's working on a Z370 MB? I bought a MSI Z370-a pro and I can't get more than 3 gpu's working at a time. The system right now is MSI z370-a pro mb i5 8600k 8gb DDR4 2400mhz Crucial 256gb m.2 SSD pcie 1x risers Rosewill 1500w 80+ Platinum PS
Windows 10 x64
In the bios I've set Above 4g Decoding to Enabled, Max link Speed to Gen 1, Set CPU VT to disabled, and Disabled IGP . I've also tried every combination of settings in between those. I've tried updating the Bios. I've tried pretty much every combination of graphics cards that I have. So far the most stable is 2x rx 580 and 1 gtx 1080. If I put 3x rx 580's then I can get into system but it acts unstable and will freeze after a little while, same if I do 2x gtx 1080 and 1x gtx 1060. and system won't even get into windows if I use any combination of 4 cards. I got it to boot a couple of times with 2x rx 580's and 2x gtx 1080's but it would freeze shortly after. It is so weird because I am mining no problem right now with 2x rx 580's and 1x gtx 1080 but if I swap the 1080 for a 580 then no go. Any help would be much appreciated. Sorry for the long post. It says that I only get one more post today so was trying to include everything I could think of.
