Hello!

I purchased the FX-6100 and am super satisfied with it! I am a very loyal AMD customer!

However, immediately after installing the chip (more than adequate cooling) and overclocking it (slightly), I am plagued with a whining sound. It is enough to give me a headache. The sound is present with cool and quiet turned off, overclocked or not. However I have noticed some patterns:

-The sound is present when i am looking at my desktop with minimal load

-The sound is intermittent, and synced with the update cycle of CPU-Z, when the application is open.

-The sound is NOT present when Prime95 is running on all cores

-The sound is momentarily gone when navigating folders

This leads me to believe that in it's idle state, the processor, or some related component is being throttled to a frequency that is audible, and extremely annoying. This is one case where I can't wait to get older.

Does anyone have any suggestions?

Motherboard: M5A97

Processor: AMD FX-6100 ZAMBEZI

Multiplier: 16.5, running at 3600 MHZ

I'm thinkin that's called coil whine, and it's probably coming from your motherboard instead of the CPU.  It's more common under heavy load than idle... but it can happen.  Your new chip probably has some power saving feature which switches on when idle causing some component on your board to start whining.  Find it and kill it... and the noise will probably go away.

You have any tips for what I should look for in my BIOS?

Disable Cool N Quiet so your CPU doesn't downclock.

The sound is due to a choke that is not as tightly wound around it's ferrite bead core. Most power supply circuitry operates at high frequencies. Sometimes the harmonics of the switching cicuit will cause some of the chokes/coils to loosen from their cores a bit and this vibration can become audible to the human ear.

Likely its due to a cheap PSU, I spent $$$ on a TX850V2 so I can indugle in any abuse I want to my CPU, GPU and RAM I want.

No the power supply is from a reputable brand, and did cost me 100$... It may not be high-end but decent for sure...

 

Its ever since i installed the processor...

Have had this happen on a small power regulator circuit on a serial port, so it's not always the power supply, however, it does not hurt to try a spare PSU in the place of the original if possible.
