Probably it's a Unigine Heaven 4 problem thinking.gif

Reference ti has 8+2phase, and a ncp4208, that is the same ncp4206 mounted on the 780/titan but can manage two power phases more smile.gif

I would if I could, but this is my first ever personal build, so I don't have anything to test them with. I doubt they would even fit in the case of my little prebuilt I have now. And I can't test them in my new build because I don't have a CPU cooler (4930k).

Many reviews are wrong & simply copy & paste the review & PICTURE of vanilla 780 & call it a day.

Any reason why I would be stable and no artifacts at 1275mhz on stock/auto volts, but if I try to increase the voltage I get artifacts and the driver starts to crash?

The GPU doesnt go above 44'c

Are you using Precision?

Mainly MSI AB, but I did notice that there were some differences with Precision with the voltage

You shouldn't be using Afterburner until beta 18 comes out. It is likely causing the issues.

When overclocking i can get to 1241mhz@1.125v but when looking closely there is a jerky feel to it very similar to micro stutter in SLI environments. When i up the volts to 1.212 and do the exact same test the jerks are gone. It doesn't seem to effect actual FPS or scores just is hideous looking closely. Also it seems that this is the highest stable long term overclock for my card. Anything higher will start to artifact after about 20min of load with any benchmark even though i have my temps under control now(after the TT II experiment went wrong).

Wonder if anyone else who is running a note worthy overclock on low volts is seeing this?

On a side note i have found both valley and heaven to not be very good at stressing the card. Even after 12 runs my card can run 1300+ for about 20min. Then if i take the same setting and jump on crysis 3 it will crash every time and crash quickly. I am starting to test stability with a crysis3 run through a certain part of the second mission(takes about 25 minutes).

Anyone know a good program that will actually stress the card good? (meaning something to set and leave going and not furmark that thing is crazy)
