I had a 980 that had two different bios. Thank God it didn't say Uber mode. I would never buy a gpu from a company that made up stupid #%^t like that. You guys should spend more time in the nvidia sub-section.
Oh look it's 588 pages long.http://www.overclock.net/t/1573308/nvidia-gtx-900-cards-custom-bios-upon-request
The restriction is not on locking down the flashing of vBIOS, it is locking down how much voltage you can feed your card. this was not locked down on fermi, and overvolting cards and killing them, with no evidence of such, was a big killer of fermi chips back in the day.
You can, of course, flash a different vBIOS to push more voltage. If you brick the card and RMA it, the AIB can tell you to go pound sand. nvidia is no longer responsible from refunding the AIB for a new GPU. Now, obviously, this varies from manufacturer to manufacturer, but locking down the stock vbios voltage wise helped cut down on a LOT of RMAs compared to the 500 series. AIBs take on the risk of replacing RMAd GPUs that have had the voltage raised outside of factory specs, not nvidia itself.
So, to TLDR: locking the vBIOS DOES NOT MEAN you cant reflash it, it means nvidia limits what voltages are allowed on the stock vBIOS, and AIBs take any costs related to replacing a GPU is they decide to accept a RMA'd GPU that has had the voltage raised outside of what nvidia allows. Make sense to you?
