HD7770 overclocking

[ConnorJoshua]

So, i've have my HD7700 running at these settings for a while now.

And i was wondering if you guys could help me overclock further. This seemed to be the limit i could get to a while ago but i didn't bother touching the power limit. Would putting this up help me go higher? The card itself is a XFX HD7770 DD Core if that makes any difference.

put power limiter to max, it doesn't increase the voltage, just allows the card to use its maximum voltage available to it.

Also you can unlock the voltage and increase that a bit if you keep an eye on temps. Just go to settings in msi and click 'allow voltage unlocking' or something.

Well, so far i have only put the power limit to 20% and i am already breaking my highest before. I'll try going untill i reach when it crashes then report back but i'm a bit skeptical to touch the core voltage

Edit: Hang on, when i set it to 1120 my screen seems to get a line that appears randomly now and again at the bottom of the screen. Am i pushing the card too far?

 

[HankScorpio]

yeah, that's artifacting. Would probably solve it by adding more core voltage.

 

[ConnorJoshua]

What's a good amount to put the core voltage up by?

Edit: MSI Afterburner keeps changing the core back down to 1174 when i try to put it up?

 

[HankScorpio]

Did you click apply? Also do you have other overclocking software running?

Just increase it in steps.

Yeah i hit apply, it's just every time I press enter when I input the voltage it keeps putting it back into 1174. I should've explained what i meant earlier by the line. It's more the screen flickering when i open a program or even scroll.
