GeForce GTX 1060 does not trigger the boost state (Solved)

MSI GeForce GTX 1060 3GB graphic card does not trigger its boost state when its GPU is loaded at 99-100% with NiceHash miner. Compare the values in the green rectangles:

GPU сore сlock is only 1544 while the boost value is 1759 and it stays the same even if I change master core clock with MSI Afterburner. And what is even more strange, the memory clock is only 1901.2 while its default value is 2002. When I start an application with relatively complex graphic interface, GPU core clock rises to its correct boost value, but memory clock remains the same:

The temperature is 52-69°C and fan speed is 47-62%, so there are no obstacles for boosting.

I have an impression that my graphic card does not boost while doing compute work (but partially boosts while rendering graphics) as described here:

Taking into account that overclocked GPU works at 2100 the miner looses about 26% of his bitcoins, the formula is 1 – 1544 / 2100 = 0.26.

I tried

nvidia-smi -q -d PERFORMANCE
nvidia-smi -q -d SUPPORTED_CLOCKS

and got the following result:

so I am unable to do something like:

nvidia-smi -ac 3505,1455

because I do not know the maximum supported GPU Clock.

I have Window 10 with NVIDIA driver version 388.13 (23.21.13.8813 with date 10/27/2017).

A quick Google search gives the following links:

While doing the Google search I found very interesting article comparing NVIDIA and AMD cards efficiency telling that GTX 1060 is one of the best cards for mining.

Finally I switched P2 state off with NVIDIA Profile Inspector that I built from sources:

Now the card switches to P0 when the mining software is started:

Compare memory clock with pictures above:

on these pictures the card is a bit overclocked: GPU +152MHz, Memory +102MHz.

With GPU +197MHz and Memory +244 MHz I have about 300 sol/sec with Zcash on fly pool (I am not sure what is ‘sol’, but I guess that it is probably ‘solution’):
