First rig set up (4 gpu's). Having problems, please help

[Bones8686]

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?

You'll want to post in the altcoin forum as you can't gpu mine BTC, or at least you would be way better off with an alt coin.

Newbie tip: go to device manager and manually have windows search for the drivers for the GPU's that aren't registering.

Good luck.

Are you using Windows 10?  If so, what version of the OS are you using, and also what version of Nvidia CUDA are you using?

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.

Have you tried one grpahics card in the first 16x slot and connected your cable (hdmi/vga/dp) to the graphics card? Or have you connected it to the onboard graphics output?

Aren't the GPU's 8/8 PIN, not 8/6?

Have you tried a cmos reset? its a pain to reinstall windows again but ive found its usually quicker to start again from scratch than troubleshoot problems on a new build. Also if you need to change bios settings i would do it before adding multiple gpus. That seemed to be my problem, but different mobo and gpus

1st, remove all the GPU's - then check your BIOS for "Use Onboard Video" and or "Multiple Display" settings.

When installing your GPU's you should put them in order PCIE2, PCIE4, PCIE1, PCIE3 - one at a time, booting up each time to ensure that your risers are working, ect...

The first thing you need to do is make sure your mobo can boot properly, unplug SSD, use only one GPU (better using your sons GPUs - GTX 770 for this test) plug directly to first 16x PCIe socket. Try to boot, if you can't, then reset CMOS (using CMOS battery). If you can boot, then go to the next step. Setup bios, use a required setting for mining such as PCIe setting and so on.

Let's assume you can boot now, plug your SSD again, still using your sons GPUs. Use DDU to clean the driver then turn-off. Replace your sons GPUs using one of your mining cards then install latest driver, turn-off and add another card one by one.
