Hi Yes there is someone here.. Are you using the onboard Sound card? what kind of noise do you hear white noise, tones??

hello, thanks for replying. in both cases (11400f and g6400) I use the gigabyte 380x gpu. It is 11400f there is noise, in g6400g, no. (Hdmi and Displayport)
In the integrated sound card there is no problem in either of the two cpus. I don't use an external sound card.

Noise is distortion:

I have 2 11400f and 2 b560, the same thing happens in the 4 possible combinations. I don't think the two 11400f's are broken. I don't think it's electricity either because just quit 11400f and put g6400 and sounds good.

If I put the 11400f and pcie 2 in bios, the sound is fixed by 90%.
