Hello dear lads,
since i have no ideas anymore i decided to ask here in forum, since there are a lot of pro's in mining around here. Maybe some1 had the same situation.
My H61 died after i tried to update it with the 6th RX 480 and i swapped it to a H97 Anniversary. Mining on 5 GPUs was pretty fine.
Installed all the 6 GPUs and started dual mining ETC/SIA using Claymore miner with -ethi 16 and -dcri 28. All went fine for 20 hours and then i decided to switch the pool. Dumb idea of mine. The rig started switching off after 1 min of mining.
I plugged off all the GPU's and started mining using one. Same thing happened. 1 minute and its dead. Already tried different risers and different Driver Versions. Did a Fresh windows 10 Install. Nothing helped. Managed to get 1 Card running for 30 mins after fresh install. Eventually the rig stopped working again. But as soon as i add another one, Claymore claims to not be able to send shares to the pool and the system freezes after 5 mins of mining. Yes, i changes Virtual memory to 16GB and used all environmental variables. I can start up the system and it works fine until i start mining - the desaster starts. Also tried other miner like genoils and standard ethminer. Same picture.
I also took 2 8GB Cards and plugged them into my Gaming Rig. pass 24 hrs they are still mining fine without any hickup. Also took my mining rig PSU and plugged in into the gaming PC. also works fine. Yes i read PSU users manual and plugged in everything as described on Page 4 of the Manual.

And i was thinking. Board cant be bad, since it works normally and stops only if beeing stressed.
So it could be board or Catalyst Driver somehow not managing. But software works on my Gaming rig, so board it would be.
Maybe any1 could help me or has an idea how i could proceed further? Sry, but i can give only 1 ETH Bounty for the solution.
