GPU Coil Whine

since both card made whine in the system i would give a look at the motherboard she could be the one to rma and if you have another gpu slot on her try the card in it to see if you still have coil whine .

What is your old system casing? Sounds like a space issue.

But the real question is my friend how can motherboard make the card squeal?

What was the old motherboard? Can you check whether or not new mobo and old mobo has the same dimensions?

what happens if you disable the winsat .

VRM coil whine is what you speak of? If so it is a issue with that MB that i found posted in other forums.

Try this, turn vsync off and tell us if there is a noticeable difference in the the whine. It should if it is the card, be a significant noticeable difference. If it isnt then it is something else. Seems like since you already tested the card on another PC and it was fine then it is the VRM no?

yeah that is the funny thing with coil whine. It seems that not only the card but also mobo and psu can have an effect whether you get coil whine or not. In this case it seems the OP has gotten really unlucky with the mix of components he has.


To OP
could you test the old psu with the new system?

easy way to tell if it is a VRM on your MOBO or you GPU, is simply overclock your card. The whine should be different or go away altogether. Good luck

EDIT: specifically overvolt a bit. Not pass safe levels! Youll notice it if it changes

if you try those card in another system and there is no coil whine i would realy suspect a motherboard issue .

this card if you stop the winsat on her does the gpu still whine usualy asus have good motherboard also unplug the sdd that is not use as os drive to see if you have any change .

All VRM whine is from is a certain frequency caused by a certain amount of voltage, but could signal a imminent failure or power issue, in any component that has voltage regulator modules. Winsat could cause voltage issues so be sure to check out what scout recommended. Other things are auto voltage regulators built in BIOS and third party software not really suitable and set to high demand gaming rigs. This is a new build so i doubt you have tinkered with this much at all.

This is a great explanation by Phaedrus2129 over at overclocknet

So your GPU has annoying coil whine, eh? Won't shut up? You've tried RMAing the card, or putting lacquer on the coils (or your GPU uses non-toroidal inductors that that doesn't work on), and nothing works? Here's a potential solution.

Overclock your card.

Overvolt it.

Do something that will change the amount of power the card draws.

Or replace your power supply with one of a different model.

The inductors in a graphics card are for the most part used in its VRM, or voltage regulation module. VRMs are a type of DC-DC switch-mode power supply, usually a synchronous multi-phase buck regulator. This means that it uses a bunch of "phases" in parallel, each consisting of a pair of transistors, an inductor, and a capacitor, to change the +12V input from your PSU to 1.xxV for your GPU to use.

In order to supply a different voltage or different current the transistors switch on and off at different frequencies. If the GPU demands more current, then that will cause a voltage drop across the inductor, which makes the transistors switch faster to keep the voltage where it needs to be. And the reverse. All this happens in microseconds.

An inductor stores electricity in a magnetic field. This magnetic field pushes and pulls on the ferrite core used in some inductors. When the voltage across the inductor changes, the magnetic field changes, and the inductor moves slightly. When the voltage changes very, very quickly (as is the case when switching transistors are changing its voltage thousands of times a second) the inductor vibrates. And that vibration, if it is between 20Hz and 20,000Hz, is audible to the human ear. Hence whine.

The frequency at which the switching transistors operates varies, but it's generally between 10,000Hz and 100,000Hz. If your GPU is whining, the transistors are switching at between 10,000 and 20,000Hz, or a primary harmonic of those frequencies. So if you want to stop the whining, you need to make the transistors operate at a different frequency.

So you change the amount of power drawn. Overclock and overvolt your GPU and the transistors will need to switch faster to provide power to the GPU, and if you're luck you'll bump them from 17,000Hz to 24,000Hz. Underclocking may work as well. And suddenly your GPU will whine no more.

You could also use a different PSU that outputs a slightly higher or lower voltage on the +12V rail, which will also change the frequency the transistors need to work at.



It won't work for everyone, and may not work all the time either. But it may help reduce the whine or the amount of time you hear it. It worked with my new HD6950. At stock, it's a real whiner. Unlocked, overclocked, overvolted, power cap raised... not a peep

well it is starting to sound like your new mobo doesn't like the card :/

Any chance all your current components will work with your old MB? If so hook up everything to it and see if the whine occurs again. Then you can for sure pinpoint it down to your MB and get that baby fixed up. Or if the whine is reproduced, it is one of your components causing issues and the troubleshooting continues.

Try changing the following.

Power cord

Different power outlet

Different surge protector /4/6/8-way adaptor

Different PSU.

Also I have heard people running their cards flat out for a few hours to fix coil whine. Let it loop Unigine or similar GPU stress benchmark for a few hours.
