Simple answer, no you can't drop an LGA2011-3 CPU into an LGA1151 socket. Make and model of your motherboard, please?
Some reading.After some searching i think that https://www.aliexpress.com/item/33028429560.html is the motherboard i got in my computer right now. Is it the same if i would uppgrade to a 7th gen cpu aswell?
