you're welcome.

I post the first 300k iters.
A strange thing is that my GPU does not reach 350W power limit(but reach 1965Mhz which is ~200 Mhz higher than it is in mfaktc.)

I'll wait both your implementation and the water-cooling version of RTX 3090.

Question Should there exists a "Moore's Law" version of the GHz-Days calculated?
