purchased Tesla V100 PCIE 32GB card, came flashed with SXM Vbios, Need help flashing back to PCIE VBIOS

[trashbag123]

Hi, my father purchased a Tesla V100 PCIE 32GB Card from eBay, and upon receiving it, we realized the Card has a different hardware version vbios flashed onto it.
The card SHOULD be a Tesla V100 PCIE 32 GB, But instead, its device ID is "DEV_1DB8", and when googling this, it comes up as a "NVIDIA Tesla V100-SXM3-32GB"

NVIDIA Tesla V100-SXM3-32GB

1DB8

Which seems to suggest that whoever had the card before us, flashed the SXM3 Vbios onto the card.
I want to restore the card to the PCIE 32 GB vbios instead. However, no matter which version of the NVFLASH tool i find (NVFLASHk, NVFLASH Cert Removed, NVFLASH OMG, ETC)
it never works. I am using the only vbios i can find on this website for the PCIE 32GB version of the card.
The card does work as is,all thought i had to use NVClean Install to add this device ID. I was able to get geekbench to run a test on the card, and thats about it.
I want to use the card for more than just TCC (which is what the card seems to be locked to, i also cant change this either)

You will need a spi flasher to do it

I suppose that the 0x1DB6 vs 0x1DB8 difference is not a VBIOS one, but is encoded in a chip die during production.

That's standard for nvidia GPUs, compare 3080 and 3090.

So I think the GPU board just was somehow refubrished with another GPU die, and you'll not be able to make it appear as 1DB6. Just enjoy the GPU as is)

If you has experience with repasting such big GPUs and is extremely interested what chip actually it have - you may disassemble it to see marking on the GPU die

That's a driver limitation. All tesla products come locked to TCC mode iirc (which is a given since it doesn't have display outputs), and you'd need a grid license to change it to WDDM.

Or you could try to do those driver hacks to passthrough the image to another GPU while using the V100 for the actual rendering.

this is the photo of the main chip, i am going to attempt the spi flash, it does not look at all like the chip has been swapped in any way. Ill update here if the flash works or does not work.
