Bolded sounds off to me. Maybe you meant replaced the old exe with the new one.
The image you attached shows setting GPUSieveSize to max, and not changing the other tune parameters. That's a quite incomplete tune. 2047 is probably too high a value for that gpu.

I've extended https://www.mersenneforum.org/showth...899#post526899 a bit, with data from my later tuning rounds on a GTX1050Ti attached there in a text file. Slow gpus respond weakly to tuning. You have a slow gpu, perhaps the equal of a GTX1050. You might be able to eke out a little gain with thorough tuning, perhaps 0.2 to 1.0%. I suggest making sure your gpu is not thermally limited, first, before spending any tuning effort. Overclocking it, as you've stated you are, makes thermal limiting more likely. Running it hot may shorten its life.

There are mixed opinions on the merits of the P106-90 gpu. https://www.reddit.com/r/gpumining/c..._3gb_worth_it/
Specs at https://www.techpowerup.com/gpu-specs/p106-090.c2999 or at NVIDIA web site.

Thermals never exceed 50c. The p106-90 has a 75w tdp.
