So just in case somebody want to mine with their rig
ETH only on two different pools, here is the content of my batch file (start_eth_nanopool_noobpool.bat):
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

This batch-file gets started from Windows 10 Autostart.
The first 3 GPUs are used to mine on noobpool (no mining fees but high transmission fees!!) and the other 4 GPUs are used to mine on nanopool (also take care if you use this pool).
The command
timeout /t 10 /nobreak waits for 10 seconds before the second instance gets opened.
Another thing you have to take care about are the risers. I bought 6 "YIKESHU" Risers (blue, 6-Pin-PCI-E on the riser) from Amazon and there are all crap! One out of these 6 was completely defect. But the other produce massive problems during the mining. All GPUs where I used these riser, got randomly stuck during the mining. After I changed all of these "YIKESHU" riser to "Ptsaying" risers, the GPUs don't produce errors any more and I was also able to let the GPU run faster with less voltage with these new riser.
So if you got massive problems, the first thing you should do is down-clock your GPUs a bit and if this will not help, you must change your risers! Risers which also work fine in my rig are the "ELEGIANT" risers which I also got from amazon.
