I am running a rig of 3070ti
I am getting hash rates between 177-179 Mhs on all the cards.
but every no and then one or more cards drops down to 128 Mhs or so (every half an hour or so for about 2-3 mins)
I have on occasion been able to get 189 MHs from some of the cards in the rig
But every time these cards touch this hash rate the others drop.
Any idea why this might be happening?
