Motherboard coil whine?

[Simon771]

So I'm struggling with coil whine in my system, and I'm not 100% sure what's causing it.

Bought GTX 1070 and Z97S krait motherboard 1 week ago. If there is no GPU in my system, there isn't any coil whine.

But as soon as GPU reaches certain load/power usage or something, it starts with coil whine.

 

Is it possible that coil whine is not on GPU, but on motherboard near PCI-E x16 slot? Is there any kind of transistor or anything that could cause coil whine?

 

When I get coil whine, I can also hear it from PSU. But just barely. Is it possible that GPU have coil whine, and because of that it's causing PSU to coil whine also?

On GPU it's much more loud and realy annoying ... from PSU I can't even hear it when it's inside the case. But just for testing I pulled out PSU 50cm away from my PC, and when I put my ear right next to it, I can hear coil whine in same rithm as GPU or from where ever that's comming from.

 

Sadly for me I don't have any other PC in house or GPU/motherboard/PSU, to test what's acctually causing my coil whine. Also I don't have any PCI cable expander, to put GPU 50cm away from my PC, to hear if whine is comming from motherboard.

 

For now I only know that when I put GPU out, there isn't any coil whine.

try overclocking it or downclocking it, sometimes it helps

most likely those are VRM chokes whining on your GPU

I did try to underclock it ... when changing power limit to 50%, there is still whine but much less.

When overclocking ... I just get more of that coil whine.

 

Also for some reason I can't change voltage on that GPU ... it will just stay on 1030mV, and it doesn't matter what I change in evga precision X software.

I think you answerd your own question in the op allready.

If there is no gpu in the system then there is no coilwhine.

So its most likely the gpu then.

 

Which GTX1070 did you buy?

[Stefan1024]

Sounds like the GPU as the noise is correlated.

 

But personally I had a MoBo with extreme coil whine and I had to RMA is. It was exagerated when doing an SSD benchmark.

I bought Founders Edition from EVGA.

They accepted my RMA and will be sending my card back to them for new one.

But if I will have coil with another one, I might just ask them for that step up program, and go for SC version.

Sadly it must be same PCB, since I already have waterblock for it. So If I go for FTW, I will need to pay another 110€ for waterblock  

 

Anyway, I hope that new GPU won't have that problem. And I sure do hope that I won't have bad coil whine with every GTX 1070 lol

It's called "coil whine" because it's caused by "coils" (inductors, transformers)

My bad, thanks for your information

the coil whine seems to be present in the 1080 and 1070 series regardless of manufacturer.

the nVidia FE and MSI gaming x have been noted in reviews. TTL and jayz noted such.

But does coil whine goes in same group for silicon lottery, or that means every single gtx 1070/80 will have coil whine?

[airdeano]

not all have commented on the whine, but it there may be varying levels of acceptance.

That's true.

500€ and 800€ worth GPUs still with coil whine ... "bellions were spent into this generation" and they can't do anything about that?

 

Anyway, thanks for your infos mate
