This board is driving me nuts! I had big problems getting just 2x ZOTAC 1080GTX to run,but managed in the end by putting them in specific PCI slots. Now I have a extra 4 cards, but I never get more than 4 recognized (most of the time I get just 3).

Tried all the tips, running latest F25 BIOS. I need to enable CSM or my SSD will not boot on the SATA port.

Will sell the full rig out of frustration soon, but before I do, any final clues?

Help rewarded....

Did you solve your issues? I am having the same thing. 4 x RX580 are working fine. When I put the fifth after some time I got BSOD with video_tdr_failure and then the fifth disapears. I am trying to solve this more then a week now.

I tried pcie 1gen, 2gen, 4G enabled, other os, igpu primary enabled, vt disabled, audio disabled, you name it ...

PSU is Corsair HX1000i, 6 x risers x1 with 6-pin to SATA, 8GB RAM, 18000-50000 GB virtual RAM, claymore's latest 12.0, latest adrenalin drivers, latest Win10 updates. GPU's RX580 with Samsung memory and one micron with gpu undervolt with cca 80W chip power output and memory overclocked, no memory errors in hwinfo, bios is the latest v25 ...

One more thing, I connected wires to power pins to turn the machine on. AC power is on enabled. However, when I turn it off on the PSU switch and turn the switch on it doesn't start automaticaly. I have to short connect the wires from power pins. What am I doing wrong to be able to turn it on without connecting power wires?
