[un]official GTX580 Overclocking Thread

[aussie-revhead]

Using smartdoctor linked a few posts ago, I am able to set the slider higher than the 1213mv limit, but in gpu-z it still shows volts as being 1213.

I can't also seem to increase the clock above what my max is at 1213mv.

Is there any way to check that smartdoctor is actually applying the higher voltage ? Or does anyone have a copy of afterburner extreme from the 2.0 builds. I have tried with 1.6beta6 and there is no voltage control.

orson - I think you will find that your 580 is also bios locked with a voltage limit so you will need to flash the vid card bios to get past 1.213v. I did this to mine with bioses supplied by a very nice member here, all of them unlocked higher voltages BUT all of them caused issues such as graphical corruption even at stock settings, luckily I didnt brick my 580, so for now I am back to the 1.213v bios until I get one that my card likes.

Hmm I whacked it up to 1213mv in nibitor which is as high as it will go.

There is another section in nibitor the "voltage table editor" looks more advanced. I am guessing this is where I need to edit but I got no idea what needs to be changed.

I did use the bios from shaminos post but I just don't know if the voltage is increasing with smart doc or not, since gpu-z shows it maxing at 1213mv.

I am guessing that smart doctor access's the vrm's directly ? maybe that is why it is not showing, but I can't seem to increase my clocks even when setting voltage to like 1.3v.

Is it possible to actually go over the 1213mv limit using software or do you have to volt mod the card ?

yeah i can up the chip to 5300 to do it but i dont want to unlock the cards, btw how you flashed them as i backuped up the .rom with nvfslash but fermi editor wont read it

and i have a .bin image also but dont know how to flash that

your chip is very nice cole but my cards will do 1000 easy at those volts
