I'm using windows 10 but I haven't been able to get back into windows since my original install. I've tried every combination of video card to pci-e slot when trouble shooting. I tried 1 card at a time in each pci-e slot, all 4 cards. Then I tried all 4 cards plugging directly into the mobo in each of the 16x slots. Then I tried a known working card in each of the 16x slots.

I then tried EVERYTHING again with a different stick of ram. Same results. No display, monitor doesn't get a signal.

Hello,

I’m having issues with my first mining set up. Here is what I’m currently using (I’ll go into the problem after);
Mobo - ASRock 970 Extreme3
Ram - 8gb Corsair XMS3 (1 stick)
CPU - AMD fx-6300
PSU - 1000w EVGA GOLD (full modular)
Videocards; (3) 1080 ti’s, (1) 1070
Risers: Ubit risers (SATA, 6pin, Molex)
(https://www.amazon.com/gp/product/B076KLJR2Y/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1)

So I set everything up and had 1 card plugged in through a riser. Installed OS, everything updated, good to go. I plugged in a second video card, turned it on and it worked fine. I turned it off then plugged in the other 2 video cards and it booted up but only identified 2 of the 4 video cards. I turned the machine off and was going to check some bios settings but when I turned it back on, my display shows nothing.

I’ve tried to trouble shoot the problem with nothing working. I tried each individual GPU in each individual slot on the board with the other 3 not plugged in (or being powered). I tried a back up GTX 770 from my sons computer (known, working GPU) and it doesn’t work either. I even tried all the cards WITHOUT risers just to be sure… Nothing.

My suspicion is that I fried my motherboard or pci-e slots?

Here is how I had the power set up (and have since learned to be wrong according to a post I found by searching).

8/6 pin > 1080ti
8/6 pin > 1080ti
8 pin > 8/6 splitter > 1080ti
8 pin > 8/6 splitter > 1070

Riser 1 and 2 on the same SATA for power
Riser 3 and 4 on the same SATA for power

Normal Mobo, SSD, and CPU power from the PSU.

Can anyone help point me in the right direction or help me where I went wrong?
