New Rig Restart Problem

[Mihaylovic]

I ve just newly built my first rig  - a 6 GPU mining rig with following components

AMD Phenom II 970
GIGABYTE GA-990FXA-UD3
Corsair Vengance 4 GB Ram
750W EVGA Supernova 750 G2 + 850W EVGA Supernova 850 G2 (connected to eachother with add2psu)
GIGABYTE RX580 AORUS 8GB x 1 + MSI RX570 ARMOR 4GB x 5

But after installing windows(win10 64bit), my gpu fans suddenly stop running and my pc restarts. Sometimes 5 of them stops 1 keeps running.
I got following error for a few times before restart.



So irritating. i couldnt even install any driver because whenever i open it it restarts in 5 10 minutes.

My PSU connections are like this:
850W - mainboard, cpu, HDD, 6 risers, 3 GPU
750W - 3 GPU

I tried different variations of PSU connections like 3 GPU 3 risers to one 3 GPU 3 risers to other etc etc. all the time same thing.
I formatted windows 2 times and also it didnt work. I got same errors.
1 additional thing i wanna ask is when i start running the system i get following screen for a few second then it starts.


If anyone have an idea about that problem, can you please advise?

Maybe you should reduce the gpu qty and try...

Try this
1) Disconnect all GPUs and connect video input to integrated GPU and see if you can boot into Windows. If yes, check if it's installed as UEFI and not legacy. If its UEFI and not legacy then go to next step or else install Windows 10 again with UEFI support.
2) Download latest AMD drivers 17.5.2 and extract them, don't install yet. Just extract them.
3) Turn off and connect 5 MSI GPUs first with correct PCIe configuration and then connect the sixth different one on the last lane.
4) Connect your video input to the first GPU.
5) Turn on make some bios mods - 16x PCIe lane speed to Gen 2 and so for 1x lane speed. Don't turn on 4G Decoding yet.
6) Start your windows and manually install the driver via device manager by pointing it to extracted driver location. (Make sure windows update is disabled)
7) It'll install all the drivers perfectly.
Restart and turn on 4G Decoding. Done! Your 6x GPU rig should work perfectly.
