Hmm okay if it was a kind of whistling buzz it could be a bad cap on the motherboard, those are all intact?
The card still draws power from the psu btw, it only goes fully through the mobo but its still gonna be 75w or something

Yeah I knew it draws power through the MB..lol.
Just doesn't get it from the Power supply directly as well.

Its an electrical buzz, like a CRT tv going bad, it defiantly comes from the cards in the machine.
This is the GTX780ti I just did a RMA on.
http://youtu.be/TXzeptWk104

The temp card is making the same electrical buzz just not as loud, wife heard it too.
MB is a ASROCK Z77 Extreme 4, system is rock solid besides this buzz from whatever video card under load you use in it.

Making my head hurt.

I've seen the green artifacts once in Valley benchmark for a split second before black screen and falling back to factory settings....crap. stun.gif

Also, since this is my first post, just want to say hey to the forum! I've spent the last couple of evenings reading through the last 100 pages or so. New to overclocking and trying to absorb as much info as I can, so far this place has been great! Will fill out my sig now...

Yes! as soon as you find the program that makes your CPU/GPU to hit a higher power state, thus triggering 3D mode by increasing the clocks, if you dont need it uninstall it, if not you can always use Nvidia inspector and force a low power state:




Then drag&drop the program exe and fiddle with the program to find your best settings! thumb.gif

I've RMA my Galaxy but now I'm stumped.

Is it possible that a motherboard can cause you GPU to buzz?

I've got a spare HD7750 in my machine at the moment, I was playing Kingdoms of Amalur and guess what I can hear a buzz from the GPU.
Can't be power now, this card doesn't use it.

When I heard it I was like ***.

Any ideas?

Coil whine will always be present whether its from the PSU, motherboard or graphics cards, as ALL have coils and can start to buzz and stop completely anytime, it depends on the frequency resonation!

My earlier article:

"Coil whine is mechanical resonance of the coil with the frequency of the signal passing through it. Physically, a coil is just loops of wire, sometimes with a core other than air. If the frequency of the signal is in resonance with the physical wires of the coil, the coil may vibrate.
There are many electrical parts/circuits which can cause whining noises, so don't just assume you are hearing coils. Annoying buzzing/electrical sound(s) are unlikely to emanate from a coil - you have something else making noise. Whining is caused by a part (or parts) physically vibrating.
Unto itself, voltage is not going to cause a whining sound. Voltage is electrical potential (actually, EMF); current through a device is dependent on the voltage across it. With a GPU, changing the voltage changes the operating frequency of various components within the chip and through the VRM sections, however something is probably in resonance with the signal! thumb.gif



Cheers all

So, as I have said on the 780 Owners Club, I recently got my hands on a "relatively cheap" 780 Ti.
http://www.techpowerup.com/gpuz/wr3yn/

So I removed my 780 SLI and put this single 780 Ti in...and damn! I wasn´t expecting it to perform this good.
On my 3x1080 surround setup with almost everything on ultra and 2xAA on BF4 I still get constant 50FPS and feels so freaking smooth. lmaosmiley.gif
With my two OCed 780s I´d get around 60-70FPS with 4xAA and it kinda didn´t feel as smooth.
Plus, this 780Ti´s ASIC is 87% which basically is more than my 780s combined. Well...ok...it is not...but you get my point. wink.gif


To be honest, I basically got this card because I was curious how it would perform for me with no real intention to keep it. But now...

Sell the 780 SLI and get another 780Ti! wink.gif

Playing the little devil on my shoulder, huh? wink.gif

But yeah, that is indeed very tempting.


EDIT: I just realized that a 780 Ti SLI would even keep up with a r9 295x2 on Mantle. (almost)

And, way more games support SLI than CFX, so there is that also!!

Got a new 780 Ti delivered today, superclocked ACX

Is it normal with this ACX cooler that the fans make somekind of mechanical noise/sound wich is not constant? When starting 3dmark first 10 sec they make the noise then its gone and comes back now and then but Always at start of the load. Guess when they ramp up.

Thanks Ed you have been a good help.
But this doesn't explain and electrical Buzz with EVERY card put under load on this motherboard. (Happens along side the whine)
Also its only just started happening, the Gigabyte never Buzzed, it was only after putting in the ASUS card I heard that noise, and I've had the HD7750 in my machine before with no noise.
(The HD7750 is my sons card and it doesn't make a peep in his machine)

The only major difference is the Kraken X60, which I will probably remove completely today instead of just unplugging it.

I'm doing a upgrade on the 29th to a Haswell and the wife inherits my stuff (Shop only does photo editing).
Hopefully that fixes everything because there's nothing left that can cause it.

Update:
Kraken gone, nothing left but keyboard, mouse and cpu fan, card still Buzzing exactly like the GTX780ti's.
Mother is the problem I'm guessing.

Guess I'm gonna have to ring the RMA department and take the $25 fee on the chin.
