High pitched whine? gx640

I'm getting sort of a high pitched whine while using the SC2 galaxy editor. If I zoom out I hear what's not really a buzz just a very high pitched noise. If anyone else could test this I just want to make sure there's nothing wrong with my gx640. It doesn't happen when playing other games (like just cause 2) and it doesn't happen in sc2, just the editor. Remember to zoom all the way out first.

 

Where is the tone coming from? The speakers? the fan? If its the speakers its most likely something wrong with the software. Does muting the computer do anything? if it was something wrong with the hardware you'd prob have seen it elsewhere rather then just that one program.

 

It could also be the CPU whine issue I've heard can happen with many Intel CPUs, though I think it's supposed to happen mostly when idling.

 

I turned the sound off, definitely not the speakers. Its almost like a fluttering sound, but very high pitched.

 

Power components methinks, i get this when starting up crysis, and some normal days its just there strangely, What HDD do you have.

 

I had / have the same issue, and it only happened in gaming so it definitely isn't due to the CPU idling. It sounds to me like it comes from the GPU (it is loudest by the vent immediately under the GPU)

 

Holy crap! I had this happen to me too but I thought I was just hearing things. It lasted only a couple of seconds. Wonder what it was.

 

I've honestly been running all sorts of intense benchmarks and games and I can only hear it when using the galaxy editor. Weird.

 

It's simple and very natural to powerful video cards.

When GPU is generating a lot of (I mean, A LOT) frames very rapidly (around 1000-2000) it produces this high frequency sound. This happens also with desktop cards but they are under the table and can be barely heard.

Relax and don't panic.

 

Hehe yep thats very true actually, could be the 2D/3D clocks rendering insane frames. (Which would make sense)

 

Oh sweet yeah I'm getting like 400+ fps in the editor so this might be it. It also seems to be around half as loud with a 300/300 d/c. However it only happens when I zoom out, which is when the fps drops to around 60.

 

Yes, I was already mentioning the whining voice somewhere on the review thread. For me it originates from the right speaker and is quite audible on windowed 3d apps on certain resolution(640x480 - my OpenGL app running with 1200FPS). Resizing window/changing resolution seems to help, or at least shifts the interference to inaudible frequency. I am glad that I hear no interference in the headphones ( on my old laptop I could hear interference from pretty much all parts in headphones - HD seeking,GPU/CPU).

 

Agreed. The headphone jack is rather high quality, and completely makes up for the speakers.
