Yeah i knew it had to be ASUS, the C7H Wifi has the problem, the C6H also had this problem.Just an update, moving all the same hardware over to the Aorus Gaming 7 has solved the pops/crackles and what wasn't apparent to me, stutter in games.
I didn't even format and he issues were gone immediately so definitely something up with the CH7.
The sad part is the Gigabyte's bios is absolute garbage and IMO Asus functioned like a Rolls Royce in comparison (especially in terms of fan control).
Gigabyte BIOS was revamped but i think is only for new boards (not sure).
I'm seriously disappointed in ASUS, i mean when i look at BIOS: https://www.hardwareluxx.de/community/f12/ultimative-am4-uefi-bios-ubersicht-14-06-19-a-1228903.html
ASUS is only one that literally just doesn't have more than 3 boards on 18.104.22.168 (and its been at least a week since)
I also still didn't forget the mess it was with Fans randomly going full speed out of nowhere either and took them over a year to get it fixed.
Either way all these new boards are very expensive, the only upgrade i see for me is the 3950X, then the Gigabyte X570 Aorus Extreme is very appealing but also very expensive.
Guess i'll just buy the CPU at one point depending on how it performs in games.
