Good afternoon, I have an AMD Ryzen 2700, and when the C-States are activated there is a noise very similar to that made by mechanical hard drives near the CPU. If I deactivate C-States, the problem disappears completely. I have tried to remove the GPU, I have changed PSU, I have tried an Ubuntu Live CD, and in all cases the noise does not disappear with C-States activated. I have contacted Gigabyte (Aorus x470 Ultra Gaming) and they tell me that if the other PSU follows the problem, that the motherboard warranty is processed.
Does someone have a similar problem? and do you know if it's a problem with the motherboard or the CPU?
Thank you very much.
