Guys, I am struggling for two days now, maybe someone could help.
I have 6 x Sapphire RX 580 Nitro+ 8 GB and I am not able to use 6 of them. My bios is modded properly and they work fine if I use up to 4 cards in a rig. But once I get more than 4 cards - I have cards visibility problem.
I have tried numerous drivers options, blockchain drivers work the best, but they only get 4 cards max to work (for some reason, they work if the patch is no applied).
I have also tried configuring motherboard bios, disabled secure boot and switched PCI-E to Gen2.
Is there any possibility that my motherboard (Asus H170) is not able to take on more than 4 cards? One of the power connectors is not plugged in (Molex/M2).
Has someone else experienced this? Does this look like a purely driver issue?
I would try checking all your connections and make sure your power supply is large enough for all those cards.
Also I've seen that after mods the drivers may need to be reinstalled.
