The Classy OC tool does strange things with the card-artifacts even on the desktop and the voltage stays the same aftre exiting fromthe benchmark.
HAve asked at the EVGA forums,but they do not know/care
Yeah mine seemed pretty good at first too, but it's been weird with anything past 1.2v. The software tool is raising the voltage no doubt. But I get a ton
of artifacts at clocks that in my experience should be stable. Not to mention the strangest crashes I've ever seen.
Here's what I mean...I ran Valley perfectly fine, more than once, at 1267mhz @ 1.2v. Seems like a pretty good card, right? Well I figured to be 1306mhz stable I'd need ~1.23v, ~1.24v at the most. But even at over 1.3v I get a ton of artifacts, even with temps in the 60C's and not throttling due to the Power Target. No crash at 1306mhz, just horrible artifacts from 1.23v all the way up to 1.3v.
And when it does crash, the screen starts going crazy. Valley will keep minimizing and maximizing, switching with whatever programs are running in the background. The screen will break up into 2x4inch squares...hard to exaplain. But it's the weirdest crashes, not just a normal freeze like I've always had before. Not sure if this is how the new drivers act for a crash though, since I haven't crashed in a good while because I was done a while ago pushing the last 780 I've had before this Classified.
And the memory...same crap. If I apply anything near +300 offset, I get these huge green star-shaped artifacts during Valley. Then with anything around +350 applied just sitting on the desktop with no load on the card, the screen gets more green artifacts and the drivers crash before I can even open Valley.
I've had unstable overclocks crash before, but this just seemed a lot different. And you would think that if the card can do 1267mhz on the stock voltage, it could do 1306mhz at over 1.3v without tons of artifacts
I may try some other troubleshooting before RMA'ing it. But the 780 ACX it replaced ran fine in this build, and this Classified runs fine at 1.2v, but not much luck with anything more.
