I need to make up my mind between 780Ti ACX and a reference 780Ti, what would you suggest?

coil whine: Remember that old TV/Monitor that would emit a high pitch scream? That is coil whine. 99% of GPU's will emit it @ some point or another, some worse than others. Coil Whine is natural, & seems to be pretty common with this new power section design. ACX & Ref are the exact same thing with a different cooler slapped on them.

First of all, thanks for taking the time to explain this!
The only problem is I am having a heard time reading the values in the screenshot.
When i tried for 3820 and Vert Lines 2160 i get all kinds of purple and green lines all over the place.

I updated my small guide with the 4K settings. Try them and let me know. wink.gif

I have a pair of 780 Ti SC ACX cards and absolutely no coil wine from either of them. Sometimes coil wine can be caused by an under power issue, not necessary low voltage but near maxing out the wattage draw. I have connected the extra EZ 12 V plug on my RIVBE even though I am only running a pair of cards so perhaps that is helping me.

Does anyone know how to get the voltage reading to stay constant, I'm OCing via precision. It fluctuates between 1.2 and 1.16v, and so does the clock speed between 1240 and 1220. It doesn't really bother me that much, but just wanted to make sure I'm not missing something here.

I forgot to add that some people can't hear it. My titans rarely do it from what I can tell, though they are in an enclosed case w/ 24 fans surrounding them, so even if they did I probably wouldn't hear it. My 670's use to cry like babies.
