How many of you have run OCCT's GPU stress test on Shader quality 8? I find that no matter what voltage I use I can't go higher than 1125 without errors in that test. Bad luck frown.gif.

that's a pretty tough test, if i can get less than 1 error/minute i keep that clock.

My old 470 produced errors at stock volts, needed a voltage bump to run it without errors.

Yeah but then if you do something such as Fold or BOINC you need two separate Overclocks, just trying to establish what people are getting for a totally stable overclock.

mine is 24/7 stable at 1125 / 1790, with default voltages. I like to have a quiet and cool system so I don't overvolt.

I could only get the core stable at 1110 MHz at default voltage with shader complexity 8. Ran it for just over 15 minutes. It would crash after about 2 minutes at 1125 MHz.
Still I'll be using 1125 MHz for daily gaming. Memory at 1790 was fine btw.
