Brakes on rx 5700xt

R5 3600, kingston fury ddr4 3200 2x8, rx5700xt red devil, b450 aorus pro, megamax zm700 tx II 700w, idcooling se-224-tx tower. 2 ssd for OC kingston 120, patriot for 1000gb.

The trouble, for some reason, there are microfoises in games, not all of them, but there are, I have no idea what could be the matter, I overclocked the RAM to 3600 at 17 19 19 38, did not touch the percent, the card was undervolted, and everything is in the drain, there are still micro breaks , temperatures on all components are no higher than 65, at the hottest point of the card is 80-83 C, under the benchmarks the card, the percentages are always consistently threshed to the maximum without any artifacts, there were never any artifacts. After overclocking the RAM, the friezes have changed a lot, but still. Firewood shows itself in different ways, the last 21.5.1 is disgusting, set 20.12, much better. I combined all the game settings in adrenaline in different ways, somewhere it is better somewhere worse, for a different game in my own way.

I dug into the net, many of them did it, but no one suggested a sensible solution.

I don’t sin on food, benchmarks, and in normal heavy games the voltage does not jump.

It often happens that in some games the frequency and load on the video card drop, for example crysis 3, load by 30-40% and 40-50 fps, and jumps a lot, and in snowrunner the same way.

Can someone tell me what to do about it ?? You are welcome.
