Ive 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 cant 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.
