You shouldn't have to be changing a bunch of settings.  Maybe reset the bios and start over.  

Sometimes you actually try to trouble shoot too much and start getting mixed up on what you did and didn't do.  It may be time to start from the beginning.  


I have done that 3 times...starting from the beginning, resetting bios and adding cards one by one.

So I have made a little progress - being a noob I have used youtube as a source to assemble my rig and i did not do what was not shown there - I have not powered mobo with/through a 4 pin molex. As soon as I did it, I could boot the system with all 6 cards. No freeze any more.
...Code 12 error is still there though...

Nvidia Code 12 error and freeze with more than 4 GPUs

Hi guys,
Struggling for a week now to get my first mining rig working...

Hardware:
- Mobo Asrock H81 PRO BTC R2.0
- CPU Intel Pentium G3260, 3.3Ghz
- GPU Gigabyte Geforce GTX 1070 G1 Gaming (6 pcs)
- 8 GGB Ram Fury HyperX Kingston
- PSU EVGA Supernova 1600 G2

OS:
- Windows 10, latest version 1709 (so with fall creators update built in)

Setup:
- 6 cards connected via pci risers, which are powered by PSU and plugged in to mobo in relevant slots
- monitor hooked up via onboard graphics

Issue:
- code 12 (not enough resources) when plug more than 1 GPU
- system freeze if plug more than 4 GPUs (post BIOS, so i can enter Bios/Uefi, but right after it will freeze, i won’t see a windows loading screen)

What have i tried:
1. EVERYTHING (hope not and you will help with the solution)
2. Windows clean install and 2 clean reboots
3. Mobo cmos clean up: incl removing the battery
4. UEFI modifications: 1 gen; 2 gen; no sound; no usb 3.0
5. UEFI drivers update
6. Intel chipset drivers update
7. GPUs drivers installation from Gigabyte, Nvidia website (manual search and automatic system scan), Nvidia app. Always through clean install. Last days only after running DDU first
8. Windows modifications: updates off, performance settings to maximum, power settings to maximum (with pci power thingy (don’t remember what was that on OFF), virtual memory: tried ranges for min from 3000 to 30000 (so tried 16000 and 16384 and many other) and for max from 16000 to 60000
9. Installing GPUs one by one, all at once, 2*2*2 and all other possible combinations
10. Updating Windows before turning off updates
11. Before 2nd clean install of windows i have tried some registery mods...suggested on the web for mining
12. Exchanges pci risers between all the cards to verify which one is not working, looks like all work well when only 1 card installed...

I thinks that is it...Please help with advices as I am very close to kill windows and try ubuntu...which i don’t want as nicehash presumably coming back tomorrow and awesome miner works like a charm as well, but both only for windows....and i never dealt with Linux ...
