GTX 600 Series Unlocked Voltage Bios' downloads and tools. - Page 318

post #3171 of 7931
Just a note for those with 660 Ti, I originally ran 1.212v and 1306 when this mod first came out.

I like to keep things as low volted as possible though and my card runs 1280core @ 1.175v with the smallest voltage table chosen in the config, definitely worth trying to find a sweet spot at lower voltage if absolute maximum clock speed isn't that important. Especially if you have the stock reference cooler.

Use the .cfg file and set the boost you want it to be, you like 1215Mhz, set that - for this to happen, you'll need to raise the volts; it won't raise your boost automagically if you retain stock volts. Want to unlock more power due to throttling while leaving the rest as-is, do that.

If I ran the below it would give me 200W power target and specific boost with over-volt. Regarding your fan related question, yeap you're setting min/max values you can set.

So if I want to find the maximum absolute clock, I should raise my voltage up to the maximum also?

How does the VBIOS compute for the fan curve? Does it implement a linear fashion?

How do i unlock my bios? Here is a picture of my gpu in gpuz.



The card is a Inn03d Reference Gtx680

Personally, i would raise the voltage to 1.1875. 1.2125 would most likely work too.

As for the fan curve, i would strongly advice you to make your own in Afterburner or PrecisionX. It is really very simple (there is a great section about it, on the overclocking guide).

To overvolt your GPU, you will first need to dump the BIOS (using the button next to the BIOS version field, right below the nVidia icon)

Next, you want to download an application from the main thread, named KGB. This will allow you to modify certain values in your BIOS, a quick writeup on how to use it can be found here:

When these steps are done, you need to reflash your BIOS, using either nvFlash or Firestorm, both can be found in the main thread. Remember to always save a copy of you original BIOS, if something fails.

Is there any disavantage at all when using 1.2125?

Regarding the BIOSes in the OP, only the voltage is changed inside those?

Also, in the overclocking guide thread why was it stated there to use the voltage bar in afterburner to keep the voltage at 1.2125 which can contribute to stability?

So this means that unlocking the voltage alone will increase your boost clock automatically without even changing it in the BIOS?

iRandomize tried to unlock my bios with kgb and works like a charm! i set power to 150 max boost 1215 and voltage to 1.187. . I tried unigine but i have a problem.. looking at gpuz log file i found that at the end of the test gpu clock dump to 1290mhz and driver crashed.
How can i do?!?

Thanks for your time

No, setting a higher boost will give a higher boost. Not setting a higher boost will not give a higher boost. Overvolting itself wont give a higher clock speed. All of this can be customized in the .cfg file.

You are clocked to high. Reduce your overclock.

So what error-id10t means when he said "for this to happen you have to increase the voltage. The boost clock won't automatically increase if you keep the stock voltage"?

I have no clue. That sentence makes very little sense to me.

What you need to modify is the voltage and the power limit. The rest can be modified from software. (Power Limit to 150% and voltage to 1.875 should be proper settings in most cases, after that we can always modify and optimize)
