Hi there nvoc-ers !

I may be stupid or definitely not paying enough attention to something as i can't for sake of me to be able to make AsRock H110 to recognize 13 x 1060 6GB GPU's. Tried with nvoc17, then 18, then 19..does not see the gpu on the last pciex slot.
It mines beautifully with 12 GPU's but there is no way i can make it see all the 13 GPU's.
The rig is built using a G4560, i tried using an i3... same result.
2 x Corsair 1000 W PSU's powering 6 gpu + mobo + risers and the 2nd powering 7 gpu's

Any hints ?

I struggled with this for a very long time. For me, it came down to a bad riser. I could have sworn I had tested and replaced them all, but this past weekend I started with one, and kept adding 1, one boot at a time, until I got to 13 working. I swear I did this a few times, but i find the pic-e risers LOVED to come loose as well, and may have had bad luck swapping a bad riser for a bad riser.

Aside from that, if you haven't, I would make sure the the 2 molex connectors on the motherboard are each connected to the separate power supplies.

Also, I noticed you have all risers on one PSU. I believe I have read that you should not have more than 2 per connector - I am unsure how many connectors are on those corsairs, but it might be worth trying splitting them up if you haven't.

Let me know if you get anywhere with this.

I put 3 risers per 1 connector - works fine

Hello guys and thank you for your answers !

Regarding the risers there are lots of urban legends, they draw up to 25 - 30 W each, measured for 24h continously, on 3 different rigs, one with 1060, one 1070 and one 1080ti's. Surprisingly the 1080Ti's draw a steady 25 W, no fluctuations as 1070's or 1060's.
As long as the rail supports it and the sum of the draw of the risers do not exceed the rated wire, you can add as many as you want.

Apparently the motherboard has a issue with the last pciex slot, as i replaced the mobo and it worked from the first boot. Switched it back to the old mobo and the same problem with the 13th card not being recognised was identified. I changed the risers with new ones, tested with the 2nd board in parallel, the same card and same riser, its final: the mobo might have a defective pciex port. I suspect a mechanical issue since the riser doesn't get powered by the mobo.

Thank you again for your support !
