Not here. ~1285 or so max stable, although I can pass a benchmark at more than 1300. I only game at 1220 or so.

One of my three cards can do 1375 core and 1900 mem. For gaming 1340 is totally stable.

It's all about temps with the Ti. They love the cold. If you can keep it at or below 35c they will thank you for it.

MSI Gaming, I tried using two pcie cables instead of one like you said, it didnt do anything for the coil whine. Is there supposed to be coil whine even when youre not gaming?

Definitely not when not gaming. If it's doing it whilst in 2D clocks that either spells that it's not the card, or it's somehow defective.

It's normally when the card is rendering silly FPS, like during loading screens and the like. On water with the side panel off I can hear mine quite clearly when benching or when games aren't fps limited but it doesn't bother me. It's not a fault, and it won't effect performance, some custom pcb cards might be better shielded that's all.


I've heard a few people over on other forums with MSI cards having fan issues. Can only suggest you RMA it for that though!

well I have gsync so the highest i go in fps is 143, unless you count that as ridiculously high, but I get coil whine in crysis 3 also and im floating around 60 fps. I also noticed a screeching sound when ever I run Nvidia control panel.

I just did the rma for tigerdirect, I just gotta send it out on thursday. Then ill pick up a classy, and see if that solves the issue with the whine. If not then im gonna have to RMA the mobo too.

I'd imagine there's considerably less whine on a Classy smile.gif

Doesn't bother me though. @ 1375 core I've come agonisingly close to a few people with Classifieds in benchmarks, but unfortunately being voltage locked, I'm falling short biggrin.gif.

Classified is definitely the way to go, especially if you want impressive bench scores smile.gif

Certain combinations of graphics cards and power supplies give different levels of coil whine so you may find a Classy gives you less coil whine or none at all, or you may find you get more.

Good luck with your RMA!

I'm using a dvi-D cable thinking I may buy a display port cable instead for my 120hz monitor, been meaning to for a while now so it gives me an excuse to do it now. But what are the chances if the dvi D port is stuffed could the others be too?

Very annoying indeed! I have had that issue with 332 drivers, in one of my monitors, now with 335 its gone! rolleyes.gif

Both 780 GHZ and 780Ti GHZ are custom PCB's (almost the same PCB as a matter of fact discounting some extra capacitors) both have 8-phase synchronous buck converter NCP4208 plus an unidentified Richtek 2-phase analog PWM labelled 0T=FG V1D taking care of a stable current supply for the the memory! wink.gif

RMA that card! The sooner the faster you get the replacement and forget about those problems you didnt pay for and dont need the stress because of it!!!
That's what warranties are for! thumb.gif

Look down for coil whine! biggrin.gif

Coil whine then, read a quote from one of my articles:

"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 eminate 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

Thanks for the explanation biggrin.gif. I just always refer to it as coil whine as it's often referred to as such. Never bothered me though as had many cards and some are just better than others smile.gif. As long as it clocks and isn't broken, don't fix it wink.gif
