[un]official GTX580 Overclocking Thread

[orson]

Trying to get some more volts into my directcu II 580's.

I used the unlocked bios from Massman's thread on the hwbot forums here http://hwbot.org/forum/showthread.php?t=26163

The highest afterburner will let me get to is 1150mv, I tried with afterburner extreme 1.6beta6 but it just bsods and when i do get it to work there is no voltage adjustment.

I enabled the overclocking EULA thing in afterburner and the unofficlaoverclocking section as well.

Also tried with ASUS smart doc and the highest is still 1150mv.

Any advice would be most appreciated.

@aussie: in vantage i have to lower my core clock 10mhz, in 3dmark11 i have to lower the ram clock a little. see my post # 126 above

@ aussie-revhead are you talking about mine or your rig?!

Yours man.

Yours man.

when i was having your same cpu this is what i did.... my 970 was a volt hungry .... 1.48v for 4.4ghz ht off

[aussie-revhead]

Nice but I expected more, what does it score with your 980 now?

Sweet cheers man.

Does this allow to bypass the max voltage limit ? I've checked the bios and it is unlocked to 1213mv. But whenever I try to push over that with smartdoc gpu-z shows it at 1213 still

P8067 for me now http://3dmark.com/3dm11/1261514

Guys do I need to flash my bios to get past the 1.213v limit? Also do I need an Asus bios to use smart doctor?

[Demo]

900Mhz really became stable with a PSU change..

[Shadow0001]

In terms of voltage requirements for a specific clock on GTX580's, and keeping in mind they are water cooled, what are most owners using voltage wise?....


I flashed the bios on the cards to allow up to 1.213 volts(from a maximum of 1.138 volts on the original bios), and i've had the cards running at up to 900 Mhz GPU/2100Mhz memory on 1.138 volts nice and stable with load temperatures for all 3 GPU's staying at 60*C, so no temperature issues and still some wiggle room left for more.

[Demo]

Im using stock VID 1.088v with 1.1v the temps really skyrockt close to 90's and the fan just revs up so bad!

[Chickenfeed]

When I was running my 580 on my 920 / x58 ud5 I was using 1.13v for 900. Now I don't know if its just the difference in boards, drivers or if the card degraded but I'm having problems even at 1.125 ( I'm noticing though in NV Inspector the voltage reading I'm getting is 1 lower than what the app sets thing to, ie 1.125 in inspector is loading at 1.13, I used to use Afterburner so may be why ) I happened to change drivers and motherboards at the same time so I can't say for sure. Regardless even at 1.138 in afterburner it won't break 50C.

Small question guys - what is cold slow bios for? Quick google says its only for extreme cooling, so is there a better bios for my water cooled 580? I havent tried nibitor etc and reading the tutorial it looks a bit tricky, can someone unlock my 580 bios so I can get past 1.213v? Or even better an unlocked reference asus bios to use smart doctor with?

Cheers.

[Sauron_Vie]

card is clocking well in 05 also in 03

how to disable OCP ? my gtx 580 only 350w on furmark ??

[p2501]

how to disable OCP ? my gtx 580 only 350w on furmark ??

Run GPU-Z with the "/gtx500ocp" switch. Needs to be done on every reboot.

link plz ?? gpuz 5.3 doesn't have that switch ?

edit, here : http://www.techpowerup.com/forums/sh...d.php?t=134458

still no switch there ?

[p2501]

still no switch there ?

It's not a button or tick box, it's a command line switch. You make a shortcut to the executable. Then you open the properties for this shortcut and put " /gtx500ocp" (notice the space before; without the qoutes) at the end of this line:

Also, cross fingers not to fry your card this way.

Will it work with the gpuz from ROG/Techpower also ? Version 0.5.3 is the same

[p2501]

I think it should since it's the same codebase. Test it and let us hear about your results.

I can't test this, it doesn't apply to Lightning cards afaik.
