If you want proof of I'm telling you get the new revision bios 80.80.xx.xx.xx and flash into your own first batch GPU and go bench , post results I would love to see it.
I do not dispute your assertion that 80.80. bios is not working correctly with first batch GPU although if some information about what is happening with MSI reference card (80.10...) with that new bios would be useful for you maybe I could test it when I get to the card, im not at the PC with GTX780 atm.
But back to the point, the whole question of my super-long post was only about if there is a chance that some GTX780 card could have GK110B board but A1 revision chip soldered on it...
Ofcourse I get what you said that 20230021 means B1 chip (20230020 means A1 chip) but that wasnt what was the question about...
@madwolfa yes that's what was on my mind
So thanks for making it clear = 99% chance there is B1 revision chip on GK110B board, if other (1%) means its homemade soldered
I highly doubt it. What's the point? I'm almost sure Nvidia would ban such efforts... even if that was the case.
Yes, but understand, for me it wasn't so clear...if you haven't some closer info about how GPU's/cards are made you can never know if this is 50/50% or as you say 99%, you are just questioning yourself - "what's keeping them from soldering the old A1 chips on the new GK110B PCB's?...if they have a lot of A1 waffers and want to spend a little money on manufacturing only one type of PCB for all chips whats the problem?..."
