first time 2700x setup/drastic fps drops

[Qwertyuiop]

i have rx480 and recently upgraded to a 2700x/gaming 7 x470/gskill 3200 16gb dual. had a no display problems i somehow fixed and its looking stable now. but now im having drastic fps drop(fps capped to 144 since i have a freesync 144hz it was working fine before-old build) but capping it to 60fps(settings ingame)fixes it. alrdy made a ddu and the problem is still there. alrdy checked any apps that i can think off that may cap my fps theyre all set to 144(radeon/monitor settings) vsync is off aswell. i have a 144hz xg2401, my ram is running xmp profile(alrdy did a memtest on stock and xmp 8 tests passed no errors). bios is updated via qflash(version F5). im using display port 1.2, monitor connected to the gpu. windows 10 clean installed. any idea whats causing this?

What in game settings are you running besides the fps cap? Do you have vsync on?

i have all the vsync i can find off(in game/radeon settings). im on max settings(dota 2, cant test other games since i did a clean install of everything). before the upgrade, everything was running fine no issues with fps drops which was 3-5days ago
