I’ve got 7 out of 8 RX 580 8GB GPU working on Cudominer. But the others all worked by changing from auto to Gen1 or Gen2. I only have pci up to 7. So I can’t change the pci 8 to gen1. Where is it? The computer does find the gpu but the utilisation is 0%
You didn´t must change to gen1. I have 20 Rigs and changed no board to Gen1. It must work also with Gen2 or auto setting. So you have another problem.
And please more information about your system. OS, Driver, Cards Bios modded?
Your question is a bit confusing, the H110 Motherboard has how many pci slots? 7 or 8? If it's 8 and your miner is only seeing 7 GPUS then start from the power supply, is the power supply watt enough for all the graphics card? Drop more details about your rig and you will find answers
You can use google or why you ask how much pcie it has? Don´t be lazy dude
