Maybe the card came DOA? Also some X-VSION cards such as RTX 4060 were mentioned on this forum not working too. Meanwhile they worked for other users (on the same laptops)

Not DOA, flashing vbios from soldered a4500 gpus made pc boot but always got code 43 because of vbios mismatch

I forgot about that.

 

You know they are sourcing the VBIOS or they are the ones who make and modify the VBIOS. You could have asked them if they could disable the "forcing 4G encoding". 

 

For example, X-VSION is so bad at VBIOSes. I wanted them to provide a DP/DP/HDMI/eDP vbios for the 4080/4090 but they can't. They said they aren't the ones who make them. Meanwhile ZRT have that but they don't even answer to my emails anymore...

I think you underestimate how much help I tried to get regarding it. They couldn't give me any modified vbios. 

 

vBIOS is made only from nvidia. nVidia has to modify it. 

 

The only reason we have rtx 4090/3080 mxm vbios honestly is probably because it's a leaked vbios for development

I also emailed Nvidia about providing a modified VBIOS for the 4080 and 4090.

 

I have their answers. They aren't the ones who make the VBIOSes. Like how??

 

Seriously that's what they told me despite telling them what I wanted. They told me to contact the manufacturer since they are the "ones" who make them. But X-Vsion isn't making any VBIOS oof

All vbios now go through nvidia ever since rtx 2000 series and must be signed by them. Only they have the tools needed to modify vbios.

Either they lied to me or I have no idea.

 

 

"Hello Den,

 

Thank you for your patience. I have just received an answer for the engineers.

 

This is what they've said:

 

"We dont provide VBios files. We have never done VBIOS updates for any of our GPUs. We just dont do it on our cards because there has never been a reason to.

 

Laptop GPUs are just like AIB (Add-In Board) desktop GPUs, any VBIOS updates created would be by the laptop manufacturer or the manufacturer of the card, not us."

 

Thank you for your understanding!

 

Have a nice day!

 

Best regards,

Actually I don't know about that, guys like on imac forums modder M0bile found ways to sign pascal vbioses to make them work with their iMacs.

 

They modified the display table definitions, power limits, clocks, etc...

They haven't been clear on how they did it, supposedely using this : GitHub - envytools/envytools: Tools for people envious of nvidia's blob driver.

That's Pascal and as far as I know, they're not signing them. Mac OS and Windows are different. From my understanding, no one can sign vbios anymore on 2000+ series. 

 

vBIOS is encrypted for the most parts. Small things like clocks can be changed still 

[JadeRover]

Pascal is signed with a Hash that changes each time you modify a single bit in the bios.

 

These guys found a way to rebuild the hash that validates the check done by the falcon module on the nvidia core.

That's what NVIDIA told me too.

 

Then who makes the VBIOS? X-Vsion doesn't make them either. They are sourcing it somewhere else... Or it's just all lies and they are lazy to change the "display table parameters"
