Okey so I have 4 Asus Strix GTX 1080Tis that are driving me insane. I have made a whole Excel sheet with different parameters and the hashrate it gives for each of the cards in my rig. Only one of them is unable to hit 45mh/s + but for some reason when all the cards are online together the hashrate is lower. I maybe get one of the cards that does 45mh/s even though 2 others are fully capable of the same hashrate. I can find a OC for one of the 3 45mh/s + cards that puts it at around 45,33mh/s, but the moment I OC one of the other cards this hashrate drops. The tuning of one card for some reason messes with the hashrate of another card. I am completely unable to get all 3 cards to 45mh/s when they are online together. What is causing these cards to act up and drop hashrate for no reason?
Additional information: 2x PSU both under 80% load and GPUs are not hitting powerlimit
