Can't override PCI-E mismatch nvflash

Not that I'm aware of. Only ways I know to verify is either observe what max voltage the core will go to or pull the card apart and look at the labeling on the die.

Looks like 1.07 - running Furmark xtreme-burnin with all sliders to max in GPUTweakIII.

That's the problem then. Maybe Veii can work some magic and get it to flash, although it will be interesting to see if the cards functions correctly and what the voltage limit is.

100% is a different card, starting with PCI SubsystemID 1043.88EF instead 9D
And different BoardID - 0475 instead of 03xx
Also noticable on running 95.02.3C.xx.xx VBIOS instead of 95.02.18.xx.xx

Even with allowed downgrade permissions, nvflash 5.780/5.789 do not flash.
It misses data for full downgrade. It doesnt know which BoardID is compatible for it to force flash.

We'll see, guess i'll have to redo work for those new Cards :)

If it's any help here's the two BIOS from my 4090 Suprim X which has the 1.070 voltage limit, might be interesting to know if you can flash other BIOS between the newer cards with the 1.070 limit. I could not flash older Suprim or other older 4090 BIOS (tried 666W BIOS that I had on my previous SuprimX), got same errors as previously stated.
Use att your own risk.
Gaming BIOS
Silent BIOS

Card is severely voltage limited and can barely hold 2950 core, on the other hand it has been 100% stable in games where I got crashes with my previous SupimX.

I dont want to spoil, as its a bit early :)
It works, maybe
Does for the rest
Got it figured out

But should work.
Only wont if they use a different (non A) chip.

Oh you would be the saviour of many! Im contemplating returning this suprim xcard to try and find any remaining 1.1v stock, altho it has great temps, no whine and is silent as a feather.
My return windows will pass in 2 weeks, I really hope you can get it to work! 😄

Unfortunately it is a cat and mice game
Release some patch/exploit. Have it emergency patched

And then ruin relationship with each of them
I got something for both, but currently its not worth it
In the sense of, the downsides are bigger than the community gain

If you want, we can try something private.
If you want to be my 4090 testing rabbit, as those cards are still rare. @Silberdachs is sadly busy.
But even if you confirm it working, its unfair to everyone else. Only helps me

I dont know,
I would like a bit more time to push it out with more things
Flashing alone can be done with an eeprom flasher too
Unless mr huang & team, wanted to hardlock it down futher.
You also wouldnt need to release such dangerous tools. :)

2080ti's were locked in XUSB FW,
A software eeprom access lock , that is secured by falcon
That bird listens to me, but usually is there to catch bugs and mice holes :)

I can't promise it will be on this site either
But its certainly not impossible.
Just wish they would keep their signing/signature server up.
Like work together, not play cat'n'mice game.
Its after all the hardware that people like. Its software is ok to be able to play around and utilize api.

An EEPROM flash, is easy and something that harms nobody.
CH431A v1.7 is cheap too.

An spi flash , via hardware is usually not a full flash
But we wouldnt need to change out much.
Its purposely not hardlocked :)
It could be, if community gets annoying or exploitive
But in the current state, its not~

Soo why not try first,
Too see if 5-10 bucks is a good personal resolve & have something to restore cards from bad bioses.
Vs releasing something that causes market segmentation for >5-6 digit $ ... and being blacklisted.

No need atm
Sure modding is fun, but a tool without extra's only benefits the lazy
Its not worth it atm :)

Yea they are on new FW and new XUSB FW

Sorry, I think I missed that post. I was just trying to determine if there was a way to know which bios on TPU would be flashable on the new 301 die cards so people wouldn't have to trial and error attempting to flash them.

Problem with XUSB FW (InfoROM section) lock is
It is software prohibited
Downgrade lock is in nvlfash
But EEPROM access is in XUSBFW - which sits in vbios rom

I think we got this down.

Hey man

if you need another guinea pig, hit me up.
Just got an Inno3D card whith with Board ID 0475 and PCI Subsystem ID 10DE.16F3 - which oddly does reach 1.1v though.
