I am in need of some assistance. I did move up to the 980Ti Classified. My AISC score was 76%. I tried to overclock to 1420 and had issues so I thought I would update the Bios. The update ran successfully but now I get a black screen when booting and it goes into recovery mode. What do I need to do to recover the bios?
 
I am trying loading off of a different card and fix the bios.

The classified has two vbioses, all you need to do is load the LN2 vbios by flipping the vbios switch on the card then simply reboot the system to get the card up and running again. The vbios switch is located by the evbot plug. Once you're up and running on the LN2 vbios and inside windows simply flip the switch back to the normal position and reflash the normal vbios back to the stock vbios.

Thank you. That worked much easier! So any insight on the why? I have the newer bios and used the file on the First post for my bios. I am only able to OC to about 1417- power target at 113% GPU clock offset is 125 and Mem clock offset is at 400. No voltage off set yet. I have tried it with a gpu clock offset at 130 and the voltage off set to 50. I am using the Furmark Test in the precision tool.
 
Also is there any issue running the bios on the LN2 position? I like the red led better than the green. :)

The reason you received a black screen is because the vbioses listed in this thread aren't for the 980 ti classified. When using a custom vbios on the classified you should really have it loaded to the LN2 position that way you never have to worry about messing up/losing the original.

Ahh, I thought it was for all 980TIs, I am somewhat new at this, been out of it for 5 years or so. Thank you!

No problem. 

why classified model have voltage lock?

We need to have a limit on the voltage even on our high-end cards. Changing the BIOS can void your warranty, and you need to be aware of that before you do it. 

sure, but for what lock voltage, al gtx 980 ti have unlock voltage...I can't understand this choice

All cards from the factory are voltage restricted. You can get a bit more voltage out of a reference card with a modded vbios. You can get even more voltage out of a classified vs a reference card running a modded vbios.

Pretty much these cards have a potential to higher in voltage but EVGA and other manufactures lock it due to safety precautions for the card which is 110% understandable 
 
What we do in these kind of forums with bios mods unlock the full feature of these cards to their full potential on voltage, this is only for tweakers who like to tinker and push their hardware to higher limits. I do not think these bios that we have in here will work for the classified ones. Correct me if I am wrong someone

How much more OC are restricted by the voltage barrier?
 
Mine doesn't even use over 105% and can't go through 1470...

What do you mean be specific? Are you saying your card does not use more than 105% or that your card is limited by the 105%?
