The laptop passes all tests (3DMark various modes, Furmark, Aida64, etc.), there are no visible problems in games either.

But with the 3DMark test, the CPU frequency very often go too low, and I see lags during the test. The test ends, the result seems to be good, but the picture clearly indicates a problem.

Any manipulations with the processor do not give any sense, I tried to put the frequencies lower, undervolting and without, there is no difference.

Attached a screenshot with the indicators.
