Hello, I'm trying to push my card as far as possible. Had it to signature clocks so far due to a fix I wasn't aware off and now I am able to clock higher.

So, I pushed the core to 1000, and benchmarked for 10minutes without any problems and temps rising to 77oC with the fan at around 70%.
Next I pushed it to 1050 and when applied sudden vertical blue lines appeared and the monitor would switch inputs from DVI to DVI, like it wasn't detecting a signal. Restarted and as soon as MSI afterburner was loaded, screen would develop horrible artifacts and environment wasn't user friendly.
So I started at safe mode and remove MSI afterburner.

And I am thinking, was it because my voltage was still stock? Should I try doing 1050+ core but increase the voltage as well?
How much voltage can these take? And temps? Can these withstand 90+?
 
Yeah you will need more volts, saying that you may just have reached the max the core will clock, but try some more juice. MSI will not let you give the card GPU killing volts, the maximum you can go is safe. Temps I would like to see below 90C.

Don't go maxing the volts out, increase the voltage by a small amount then test for stability, keep doing this until you get a stable core

aight, will try upping voltage by 0.05v a time till I'm stable at 1050 then go from there.
 
I've gone up to 1.3V still not stable.
Basically it is stable in windows from 1175 and upwards, but I'm running at least Furmark bench to see temps and if it's stable for at least that. And its not, it goes up to 33-48% and then freeze, then input signal goes to DVI again, artifacts and have to restart. Should I give it more juice than that?
oh btw for those 30-48secs of furmark temps rise up to 83.
