I have recently tried to manually overclock an AMD APU, ever since there has bee a high pitch noise(kind of a ringing in the ar kind of sound) coming from my APU, The noise disappears when it is underload, or strangely enough when I am browsing the netflix instant suggestions carousel. I have eliminated all the usual suspects, RAM, PSU and Motherboard, My guess is the problem is being caused by the amount of voltage that the APU is receiving , is there anyone who has a solution

Processors are not known for making any kind of noise, they don't have any moving parts. What you are hearing is located very near the APU and making you think the APU is the source when it's not, most likely a transformer or torriodal choke on the board that is part of the circuit supplying current to the APU

How do you know this sound not came from your motherboard and psu..?
High pitch noise usually came from coil..
Happens alot in graphic cards, and powersupply..and motherboard too..

I changed the motherboard, bread boxed my ps, the noise was still there and I used different ram, I know it's not coil whine it's the high pitched sound made during a hearing test. I don't have a discret graphics card. Like I said it goes away whenever it is under a temporary load like opening and running a program like my anti-virus

So what could I do exactly? I changed the motherboard and i still get the same problem, do I need to change the voltage or something to that effect? I probably should. Have mentioned that at boot up I get a red led light from my mem ok, I installed different memory and there was no red light but the noise is still there
