I have a couple of Nvidia G1080 cards and a MSI Z170 motherboard with 7 slots, and the hashing rate decrease significantly when I use a riser cable. When I plug the card directly in the PCI slot, then it hashes at full speed. Does anybody know of a solution?

https://www.amazon.com/6-Pack-PCI-E-Powered-Adapter-Extension/dp/B01N3UVJHM/ref=sr_1_1? do not use them.
lastly are you crazy and feed tons of power to the card.
you should use msi afterburner and set to 70% power.
since I do not know what you mine I can not give more settings.
