Yes. If you were to take the bios itself and look at it, it would be machine language. That is, it would be raw binary, and you would have to divide it up into bytes and then be comfortable enough with both assembly and the chip's instruction set to interpret what is going on. A decompiler of sorts might be able to help with that.

From there, assuming clock management is done internally, you would need the datasheets of the NVIDIA chip in order to find the address/register of the clock multiplier and divider. Then you could probably search that and find where these registers are being set, and change those values.

It would be nice if things were as simple as you say, where there would be just a bunch of C++ text files or INI files you could edit. But these languages only exist to make the development readable by humans until it is parsed and turned into raw binary.

Basically, instead of being given the works of Shakespeare, finding out the language, and then editing the course of the stories, you are basically just given the raw neural information from Shakespeare's brain, displayed by an arrangement of cracker crumbs and birthday candles. And of course, NVIDIA was nice enough to shake it in a paper bag then melt it solid in epoxy.

Thanks for the offer of effort, though!

This isn't even the issue though. It would already be done if understanding the binary was all it took.

Sadly it is encrypted, it will not flash a bios which hasn't been properly signed with a public/private key concept. This means that to understand it you first have to decrypt it, modify it, and then have the key to be able to re-encrypt it correctly.

The technology exists to sign new BIOS'.... the STOCK BIOS' had to be signed and that's what we need.. Technically we just need the tool/process that the vendors user (unless NVIDIA keeps it in-house, then in that case we need it from them...).

Someone needs to just accidentally let it fall of the back of the truck biggrin.gif

(or bypass the whole thing completely...)

I suppose that everything is kept at Nvidia laboratories and none want to lose his job. wink.gif

I was really happy with my gtx 1060 6gb.. Until I found out they cucked me.

Now I hate my gtx 1060 6gb.

Sure hope Vega brings it!

I suspect bypassing is what MacVidCards is doing? i.e. programming the BIOS directly onto the chip? Is what validates the signature just the flasher program? If so that's the easy way to bypass it right there...

MSI and other vendors overclock using the bios... if only we knew their ways.... thinking.gif

The percentage controller allows you to effectively increase the voltage within predefined limits recommended by Nvidia. You can always set the slider to the max spec, however that would reduce the life span of your GPU to one year. - Tom Petersen

And Joe Dirt mentioned quite some time ago about Hulk certificates for Pascal BIOS tweaking but AFAIK no one approached manufacturers to request them using the user request option in nvflash. Possibly the mention of money and no free lunch might have had something to do with it and probably the whole idea is now on the scrap heap now due to lack of participation.

I did talk to an MSI rep but she said by getting that Hulk cert, I would have to both prove that: I have an MSI GTX 1080ti card, I'm a pro overclocker and I need to void my warranty. I obviously didn't qualify for the 2nd point lol. So I went fck it and bought Gigabyte.
