so far my clock looks like this 24/7.... 927/1854/2304 @ 1.1v

I was wondering will 1.1v be enough for a 1ghz overclock???? I don't want to try and crash right away since my board is such a hassle to get back from a bsod... that's why i am asking

i am using the evga superclocked version so it came at a stock 1.088v.... i upped it already slightly to 1.1v, what volt do 580s generally need for 1ghz?

There is no 100% guaranteed that the card even reach 1ghz without any vold-mod.

I have 4 cards. 2 of them can reach 1ghz at 1.2v, and one can only reach to 970ghz and will not go over that no matter what.

Only one who can say if you card can reach 1ghz, is you. You already run it at 1.1v, so start upping the core.

Even though some cards have a low VID to start with, doesn't mean it will OC to 1000core so easily.

Some chips top out at a certain frequency regardless off volts fed to it.

I think you'll need atleast 1.2v to have a fighting chance for 1000core.

Goodluck, I hope you get it. It's a nice mark isn't it?

The 580s don't have an issue.

The 570s and 590s do.

Even tho the 580 has 6 VRMs, it still have issues at the 1.2v area.
Pushing it there for long will kill VRMs.
For 1.2v stable and above, you need volt mods.

1.1v is safe for 24-7 right?

anyways... how do you go about doing a volt mod... anyone have a "how to" website i can go to?

EDIT: google is not yielding anything regarding a 580 volt mod guide

Make sure you know what this is the way you want to.
The 5xx series has a hard-settings of 1.2v max. You can not raise it by by updating the bios anymore.

The only volt-mod is a hardware one, as in connect an extra molex to the GPU and wire power using capacitors to the core.

This kind of mod is going to completely void any warranty what-so-ever, and you will have a very hard time selling the card later on.
And if you screw up, its gone. The card is completely ruined.

So think carefully.

And as these GPUs are not that old enough, no one really knows if 1.1v is safe for 24/7 for the long run.
Most likely it is, but you will know only in a year or so
