still none of this gets me past the error of "Cannot open BIOS file" and I extracted it from GPU-Z just like everyone else and I am launching both with Admin Privileges

Versions 0.6.1, 0.6.0 and 0.5.0 all do this
can someone help me figure this out?
My directions listed on the last page work on Windows 7, I've tried it without problemQuote:

When the other card is at a solid 1359 this card drops as low as mid 1100s also the voltage drops as well. I have them set to 150% obviously.
I have been playing around with the 'other' Kepler bios tweaker tool to try and force it to use max clocks but that seems to lower the volts with every increase in boost clock. So I'm gonna try again with KGB.
Has this problem popped up before? could it be because the card doesn't like 1359? or the 150% power target? What should I try to fix this?
It did seem fine to begin with. I have tried the card in different PCIe slots and got the same results

Thank you!
Lol, I can't believe I didn't notice that error when I first looked at your post. It's basic DOS syntax :)Quote:

@CrazyNutz
Is the feature of modifying the memory clocks even possible to add in KGB? Or is it not easy at all?
Yeah, use the correct version.Quote:

bentez2003 - The VRM on the card may be overheating, I had very similar issues on my DCU II's which I eventually tracked down to VRM temperature.
No it's not hard. The hard part is trying to find some free time to work on KGB :) I've been swamped lately. Hopefully I can free some time up soon.Quote:

Thanks for the info STEvil, is there any way to fix this?? I can't seem to get the voltage to remain stable no matter what I try..Quote:

It's just that the default max boost clock of my vBIOS is 1267.3 and when I unlock the voltage to 1.212 it immediately reaches that clock without any problems. If I want to increase more should I just increase max boost clock with your program? What EVGA Precision X and MSI Afterburner modifies is the boost clock by adding an offset and not the max boost clock. What your program basically does is modifying the Kepler Boost (Max Boost Clock - Boost Clock) which is practically increasing Max Boost Clock also.Quote:

You don't "automatically" reach anything, you have to see what is stable and turning up the max boost clock only allows for a higher frequency, key word is allows. If your card can handle it, it could go up to the higher speed you changed it to. Changing that value has nothing to do with how your card will OC in general.
That was exactly my point. So in order to increase it further you will have to use software overclocking in order to increase the Offset. Let's say my card CAN be stable at 1300MHz. Setting max boost clock to 1300 just "allows" it to reach 1300 but there's a chance for it not to reach that "automatically". Then that means, as I've said, you have to resort to software overclocking to force your Offset (hence Boost Clock) to be higher to reach 1300.Quote:

You have to use software OCing apps in general to control Power Target, Voltage, Clocks, etc. So I'm not sure how you could do this without software apps.
To plug my own article :D, If you are wondering what GPU OCing App is the best or has the features you are looking for, give my article a read: http://videocardz.com/35604/gpu-over...ng-apps-review
It pretty much includes any software that works on all cards (no vendor specific software like TriXX) and even has an interview between the creator of RivaTuner (Alexey) and myself.
Great. Thanks for the help :)Quote:

First of all i want to thank author for software ! :yepp: :up: Its great oportunity to test things out :)
i have KFA2 GTX680 4gb OC ED ( http://www.kitguru.net/components/gr...-ex-oc-review/ for spec)
and KGB'ed its rom and flashed it and this is what i got now by default:
http://clip2net.com/clip/m120883/136...clip-284kb.jpg
i used this kgb.cfg:
Fan_Min = 30
Fan_Max = 100
Max_Power_Target = 150
Max_Boost_Freq = 1280
Voltage = 1200000
and this is my original .rom file
https://docs.google.com/file/d/0B0Bv...it?usp=sharing
why cant i set Power Target to 150% in Afterburner/Inspector ?
And i cant change Voltage in 3D also, im trying to change it but when i run Kombustor i don't see the difference, screens:
[spoiler]http://clip2net.com/clip/m120883/136...clip-241kb.jpg[/spoiler]
Something went wrong?
Voltage should stay the same in 2d mode ? (never OC'ed videocard before, sorry if noobish)
So I flashed my cards and set the voltage to 1.20v, but I get artifacts even doing it at the same level overclock I got before the flash. So my question is, is there such a thing as too much voltage for the GTX670? I am water cooling and temps have not gone above 46c. According to GPUz I get 1.21v max when benching, so I am wondering if I need to lower the voltage in the CFG file to the default 1.18v. I was hoping the added voltage would allow me to hit 1254Mhz on the GPU, but if it is going to cause artifacts then there is no point. By the way, this is easy as pie to do, love the program still, thank you for all the effort CrazyNutz.
