Would love it, if someone would be able to help me with this one.

I built a mining machine (7x rx570 4gb nitro+, MSI Z170A pro carbon, 120gb ssd, 4gb ram, celeron G3900, superflower 1600W PSU, 7x riser) and put it in homemade open air case.

I installed windows on it, flashed bios on GPUs, configured all the details (4g encoding on motherboard, copied older version of drivers to new folder so windows detects more than 5x rx570 etc) and started mining. Was happy to get about 29 MH/s in dual mine mode. I quickly found out that one of the cards was faulty (got memory errors even with stock bios and stock frequencies) so I sent it back and happily mined with 6 cards. Also cranked up the fans, so temperature on each GPU was about 50 degrees celsius.

I got the card back, but this one was faulty as well (rig would not even turn on, even when switched to different PCIE slot, different riser and switched to secondary bios). So I sent it back as well.

Then the supplier told me, that they could not supply the chosen GPU if I would be OK with Gigabyte version of RX570. I said sure, as long as I got something right?

Now the weird shit started to happen. I hook up the 7th card and screen stays black. I turn the machine off, disconnect the card, turn it back on and windows started to repair the disk. I leave it for about an hour, the repair progress is still at 0% so I decided to reinstall it. I reinstall win 10, do all the configuration with drivers, start mining with original configuration and I notice 2 cards were mining with 22 MH/s. But it was late and I said, fuck it, I'll deal with this shit tommorow. The next morning I check mining status and see that the machine stopped mining at about 3 am, screen was black. I turned the machine off and than turned it on again - nothing.

So I try each card by itself - same results. I use the cards bios switch to switch to secondary (the quiet one) bios and windows starts up normally. I flash the primary bios again, thinking something has gone wrong, with the primary bios, restart the computer and again nothing - black screen. I switch the bios again to secondary and I am thinking maybe the bios chip is somehow damaged. I flash the secondary bios with original primary bios and now I get black screen even with that. At this point I stopped playing around and opened this thread.

Any ideas what has gone wrong and why the cards wont start up? I will probably do the 8+1 trick and flashed the secondary bios to the original one, but I am abit in the dark here.

I am willing to reward the person that gives me a solution =)
