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?
