Dear Valued Customers,
 
We do have a BIOS update available for these GTX 780 Ti Classified cards, but it is a unique and secure link for the download. If you can please respond to me through email at  with your registered serial number for this product and I will email you a response with a secure link for the download. The update is only available when requested through email and we do ask that it is not posted online or distributed outside of this process.

Hi I want the bios fix I just received my ti classy aylan196@gmail.com

Send an email to chrisb@evga.com and you can get it.   Posting in here will not get you the secure BIOS fix.  He will simply send you a message and state to send me an email with your registered serial number.   

The first post was 7 hours ago..  You emailed them over the weekend,  I suspect,  and just like others,  they have days off.   Chris is very quick about responding,  but it takes time.   You are on the other side of the globe,  so be patient.   You will probably get it as soon as he checks his email.

May I request the bios please?

You have to register you card first with evga. Then you have to request the bios via email along with your registered serial #... Then will get back to you..

I just got my card and i must agree im not very satisfied with it for a $759 card ($789 with backplate). I emailed chris yesterday morning and still havent heard anything. Is there an easier way to flash the bios onto it? Nvflash seems like a pain in the ass to get going. Setting up a bootable flash drive or having to use extra software if windowsn wont make my flash drive a bootable dos drive then loading up the bios.......Just seems rather involved. Anyway i dont so much mind doing it but i need the bios to do it with. I'm very disappointed they left it locked in the first place. This card is making me miss my 560ti classified. 

If you get the official EVGA updated bios it is just a EXE file you open and you just press yes and it flashes it for you. I used it to flash my classified.
 
I used nvflash with my 680 asus and it was pretty easy. didn't make a bootable USB stick or anything just did it in windows. 

I cannot believe this flashed to 2nd bios (boy am i happy i did that and kept my original flash) using latest nvidia driver. says update successful. I restart. Everything looks ok but occt crashes without me even oc!! Then display drive crash. I power off and went back to my original all is well. Dang what is going on here folks??? Windows 8.1....

thanks for trying to help but as i stated I am running win 8.1 and I left the bios stock.  no oc.  I ran gpu test in occt.  I posted in here to report my experience.  Honestly since I am happy with my non evga bios flash i have no interest in fussing with this more.

Guys someone maybe try to mod and unlock more voltage on GTX780Ti Classified or K|NGP|N Classified in Afterburner?
Cards with CHIL8318 with official BIOS.
I saw how people unlock reference GTX780Ti with different controler but not CHiL8318... and on overclock.net I saw skynet
explanation how to unlock ASUS GTX780Ti DCII with VDDC CHL8318 to 1300V.
His explanation is to people put this in AB Profile file VEN_10DE....
VDDC_Generic_Detection = 0
VDDC_CHL8318_Detection = 44h
I try that but I didn't get nothing under Core voltage slider in AB,  Empty.
Than I remember in AIDA64 write NV Diode, 46h...
and I set
VDDC_Generic_Detection = 0
VDDC_CHL8318_Detection = 46h
and now I see this...
 

 
 
I must repeat before this change in AB 4.0.0 I saw VDDC Controler Display Driver...
Maybe someone want to try to OC without Classified Voltage Tool, maybe even this work and give little more voltage option.
Who have watercooling and good PSU....maybe this is way for 1300V without unofficial BIOS and Classified Tools.
 
 
I only know I will uninstall now software delete file and install again, but maybe someone love this things.
Work and after restart PC, after reset back Voltage on 0.888V.
