	Fixed !! this was a riser problem ... maybe mixed with a driver issue ? I purged all the drivers and nvidia stuff, reinstalled the ppa and reinstalled the drievrs anew. Then, i had to put a new riser as it firstly was still not recongnized. Then I gradually put all my cards. Now they are all recognized

	Hi yes, i did install 2 4 pins molex, one on the card one on the riser (is that what you mean ?) About the riser cards I am using, they look pretty standard indeed, bought them on amazon (https://www.amazon.fr/YIKESHU-Riser-Powered-Adapter-Extension/dp/B072Q29937). Not that I powered the riser directly from my Power Supply, same power supplies also powers the GPU.

	Hello, despite all my tries and efforts, my brand new H110 BTC+ pro mobo does not recognize more than 1 MSI GTX1060 GPU. I am running Ubunutu 18.04 LTS, latestd Nvidia drivers, GPUS are mounted on risers. Power supply is 1000 W and I want to put 4 of those cards for a mining rig. I carefully followed all the cabling instructions, BIOS looks OK ... only 1 GPU is recognized. I tried to swap GPU's, risers, same result. Am I missing something here ? Thanks, Jacques
