WIN10+Afterburner: I can confirm that delay applying OC helped. But few more times even after DAG I try update drivers to latest v465.86 but after restrt same issue with 3070 carts - invalid shares. So i put 2min delay between miner start and After Burner apply and all works without invalidshares - seems like some issue with miner and new cards? Especially with 3070 ....
With new RTX 3070 i am getting lot of incorrect shares in miner but no incorrect share reported on pool.
PhonixMiner 5.5c - ethermine.org
I only find ot by seeing graph at pool - reported hash rate is same constand, but avg and current start droping down, also shared go down.
I try remove OC (put 0 / stock value), but still see incorrect shared on RTX3070 cards.
Any idea?
