Why does the 970/980 coil whine with Core15?

Why does the 970/980 coil whine only with Core15?

Maybe it's the way the WU utilizes the GPU? IDK. I'm lucky that my 7950 is the only thing that has any coil whine in my system, and that it's a very small amount.

[Uwillparish]

it dont, i had horrible whining with my 970 in my i7

[Bonesy]

Does it on the 960 as well....probably how it's using the voltage/core - as you can change the "pitch" of the whine by adjusting speed, lol

[simtransporter]

coil whine seems to be pretty random, i think it can depend on so many factors which is why everyone seems to have a different expierence with it.

[Megahurt]

The temperature on my 750Ti goes way higher on core 15 than on core 17/18. I guess it's just because it uses more power/causes more strain on the gpu.

That does a difference for you? I can only change the sound with the coreclock.

 

Edit: How, setting it to medium makes it more annoying.

Ya that's what I meant...hadn't heard the coil whine before, so thought maybe I OC'ed it too far or something(was doing so the day before), so I started to adjust the speed....and then just started laughing. Wish I had a spare card  I didn't need; I'd make one of those christmas song remixes you see on youtube, using the core clock slider - lol

LOL, that would be pretty funny. @LinusTech has enough 970s to do that.

You, sir, are a noob. Not because you don't know, no, but because you don't even TRY to. Learn to pursue things, instead of waiting for others to give you everything.

Some people need more personalized answers. That justifys his topic.

And if there was an exact same topic like this, he would be called lazy not a noob....

This is a good question. My 970 didn't make a peep with my core2extreme but when I put my 4670K in it didn't take long to develop.

Of course my CX600m ended up taking out two cards in a row before I figured out it was bad so that had something to do with it.

I wonder if it has to do with the CPU handling the PCI-E lanes now.

[Xsilent(X)]

does this coil whine happen with other drivers? if yes please tel me.

[Syte]

Why do people call Intel Core i3/i5/i7s core 13 15 17 sometimes? I know the reference to folding but I'm refering to the reference in CPU.

This is extremely common but I can't discern why.

These cards are known to have coil whine issues. I have a silent build setup with 2 EVGA GTX 980 under EK-WB water cooling and they don't have coil whine.

I have noticed a large portion of 970s and 980s I work with do have noticeable coil whine though especially when under heavy load.

[Me1z]

It has to do with how the core itself functions. My understanding is with core 17/18 the GPU only acts as a co-processor while the CPU handles the actual physics calculations, and for core 15 the GPU runs almost completely independent and handles all the calculations itself. The end result is core 15 absolutely pummeling your GPU, causing it to scream like a banshee. The good news is that core 15 is "End of life" status so we won't need to put up with it for much longer.

You have on folding (Work unit Cores) and the are named after Core15 Core16 that one is pretty rare these days Core17 and Core18 these are GPU folding cores.

Only in Core 15 and when reaching 3000+ FPS in gaming.

[MeepLikesToBuildPc's]

Lol

It indeed starts to get annoying when my 780 starts to whine like a little girl thats Being killed when I get 2000 fps in minecraft lol

Could be something to do with this...

 

 

"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". http://www.overclock.net/t/1094728/possible-fix-for-coil-whine

 

My 970's doing it when I fold. I'm probably just going to stop folding on the GPU.

Bringing up an old topic - sry - better than posting a new one I guess...

 

GPU - Gigabyte G1 970

PSU - EVGA Supernova G2 750

 

The card will ONLY whine when folding core 15 work units

 

Furmark - silent

Gaming - silent

Heaven/other benchmarks SILENT...

 

Overclocking/overvolting make it worse (when folding) I can underclock it and it goes away but wtf - I bought a G1 for a reason...

 

Very strange that it only happens under this one particular load, even in furmark at stock and overclocked to 1.5Ghz its silent, start up a core 15 WU and it screams....

 

 

Just wanted to add my experience, wish there was a way to avoid core 15 WU's... I can make this thing change pitch by messing with voltage or clock speed when running folding core 15, otherwise is silent under all clocks/voltages even under more extreme conditions than folding like furmark - very strange....

[GlassBomb]

I too wished that there was a way to avoid Core 15 Work Units. Not because I don't want to do them, but I just don't want the coil whine.

 

But I keep plowing through, doing whatever is given to me.

The reason core 15 causes coil whine is because of how GPUs run them. With newer core 17 and 18 units(and all modern games/benchmarks for that matter) all of the physics calculations are offloaded onto the CPU and the GPU acts like a co-processor, but the older core 15 units are completely self contained and force the GPU to do it's own physics calculations. This puts a lot of strain on the GPU because its something they were never intended to do (There's a reason technologies like PhysX never really took off). Heavy strain on the GPU requires more power at constant levels, and to keep up with that the capacitors are firing much more often. This creates an audible vibration that we perceive as 'whining'. The way I try to justify it is that a happy GPU is a singing GPU
