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. :)

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!

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

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%?

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.

wrong you can't mod vbios for unlock voltage, only with classified tool can go over voltage 1,212

Right... that's why my reference card can do 1.28v with only a modded vbios.

Hello guys. I flashed the overclocked bios version 1 of this thread and it runs really well. The problem I am having is about temps. My temps are high when playing reaching 86-89ºC with almost reaching 100% fan speed. I don´t know if this is normal but I also stay a little bit concern about staying in this temperature when playing. Btw I have a 144hz display and play games in 1080p resolution. I like to play COH2 and is really a demanding game to reach more than 140 fps with 980ti. Is someone having this problem? My room temperature is about 26ºC because I am in summer in my country. Thank you.
Oh, I also asked for EVGA for the latest bios and they sent me the version 84.00.41.00.F0 for GTX 980TI SC+ (06G-P4-4995-KR) and I think could work with both v1 or v2 cards. Mine card worked with V1. I am sharing with you guys both original and overclocked vbios based on the same condition as V1 posted here. drive.google.com/file/d/0BxKw33k4xEnwYTJzMDZxUjV6Uzg/view?usp=sharing

The vbios does use increased voltages. Your card shouldn't be getting that hot since you're only running one card with the acx cooler at 100% fan speed. How hot does your card get on the stock vbios @ 100% fan speed versus 100% fan speed on bios 1?

My card in stock bios 100% fan speed reaches 76ºC running heaven benchmark X 89ºC on bios 1 

76C on a 100% stock bios @ 100% fan speed. wow. You should try redoing the thermal paste on your card.

Hey guys, I'm fairly new to modding my vbios.  I recently purchased a 980 ti classified with an ASIC quality of 68 percent.  I would really like to find a vbios for my card that is stable, but pushes it a little further than I have been able to with the stock bios.  Ideally, I'd like to get it stable over 1500mhz.  I was under the impression that these cards were great overclockers and unfortunately I have seen instability at core clock offsets as low as 50mhz with fans, power target, and temp limits maxed.  This is with stock BIOS and nothing else touched.  Is it possible that there is an issue with my card?  Or do I just need to find a modified bios to increase the stability of the card itself?  I appreciate any insight you guys can give me!

Most likely just need to tweak your vbios a bit.

Hello guys,
Any one have a possbile GPU CLOCK OFFSET and MEM CLOCK OFFSET on default Voltage for EVGA GTX980ti Hybrid? I have tried to set GPU CLOCK OFFSET @ 60->100 and MEM CLOCK OFFSET @ 400->500, but I can't archive the result that review websites post. What do you think? Maybe I did something wrong or I just get a bad card? Thank you!
