[Official] NVIDIA GTX 690 Owners Club - Page 486

Yes

Edit: bricked the card this morning, but have fixed it with modded hydro copper bios via DOS. Now got voltage control to 1.3v.
Have been able to run 1240mhz on both cores, but power limit keeps crapping out if I go higher. Already created a custom bios with PT 300% but that doesn't seem to do anything (slider in AB goes up to 200).

So for anyone getting the hierarchy mismatch error trying to flash their GTX690 under windows, solution is to do it in DOS.

Thanks grunion for putting me on the right track.

If you use the latest version of Nvflash for Windows you will not see that hierarchy error anymore...

Tried that, didn't do anything for me.

This one: NVFlash 5.142 for Windows ?

I guess not a lot people asking for modded 690 bios to remove power throttle. May have to ask some experts to look into it. 690 is tricky with dual GPUs and this is why we have not seen a successful modded bios that remove all other kind of pre-programmed throttling. But, I bet someone knows how to do it....make a post in various forums including this one and you may be able to get some help. Just an idea

Yea I guess it all boils down to that. I can set 1.3v on my GTX690 but the power limit is holding it back (max 150%). I've already made a custom bios with 500% power limit, but in reality it just doens't go higher than 150%. Been trying all day with different custom biosses (vendor and different settings for max. voltage and powerlimit)
I was able to complete GT2, GT3, and GT4 in 3dmark11 @ 1241mhz (where I could do 1215mhz before), but GT1 throttles like crazy and makes the card downclock all the way to 1050mhz.
So for us GTX690 owners it might be nice to finally have voltage control, the power limit is still holding us back.

Maybe Skyn3t or someone else can look into this?

If you set Power Limit to 200 it will work, ive mine on 200%!
post #4859 of 5564
I've actually set it to 500 on my current bios, but it still hits it, that's impossible wink.gif
