Nevertheless let me ask you how can you fix to the P0 (or any other) state on Pascal GPUs? I have both Windows and Linux machines so I'm interested in both OS.
Use Nvidia profile inspector to force p0. P0 is just to fix MC. So that it won't exceed stable MC on closing the miner. With P2 stable MC while running miner is 5800 (for example)?, and when closing miner for a short period it jumps to 6000 (for example) and driver crashes (or the whole system freeses). Thats all.
