Hi,
Is it possible for the Pascal-based cards to enter the p0 state by normal means (without manually clocking)? Using Maxwell cards, the GPU will enter the P0 state when running a tensorflow process. However, we noticed the Pascal cards will enter P2 state (not P0) when the same tensorflow process is running.
