780TI Classified Overclocking

Good afternoon guys, I've recently just received another 780TI classified to play with and I'm not sure whether this card just didn't get any silicon or isn't how it's suppose to act. From the boost that EVGA apply the core is 1137 and the memory is clocked at 7000Mhz. So I applied a rather basic overclock of 50Mhz on the core and 200 on the memory just to get a little boost but now wanting to take it further as soon as I put 60Mhz there's artifacts so I thought ok maybe it needs a little more voltage however the more voltage I give the card the worse the artifacts are. I thought these cards were supposed to achieve 1300/1400Mhz on the score and like 8000Mhz on the memory?

Any input would be great did I just lose on the silicon lottery or is this a dud from EVGA as I thought these chips were supposed to be binned to allow massive overclocks?

Can I do this with an EVGA card though?

Just tried it doing FlashVBIOS and selecting the new bios then, enter, enter on Nvflash and it said Flash bios failed?

No reason why not. I flashed my Inno 670 a number of times with it. It's not Zotac specific, just a windows bios flashing tool. Just remember to run it as administrator.
 
Kelt how does it work simply link flash vbios, select rom file then nvflash comes up with enter to continue or q to quit I'm a little lost mate
 
Hi, the chips on the classy cards are not specially binned, what makes the difference is the powerfull PCB and power management we do use. For this it is best to flash one of the BIOS out of the King Pin Forums on the card and use also the Classy Overvoltage tool you can find there. With this OV Tool you can then raise the core voltage to 1.35 and also raise the RAM and the BUS voltage. With the 200% power target in those BIOS with the increase voltage you can then hit massive overclocks. If there are any issues using NVflash I would suggest to review some tutorials at youtube vids and set it up simultanious to what they do in the video...
 
Hey Dominik did you see my emails ? I can't seem to flash it at all :( thought it was a simple process

Also I can't seem to download the classy BIOS could you email it to me please ? ;)

Not quite getting you. Nvflash? Linking?

Download, install and run Firestorm from the link I gave you.

Click on the "bios" button at the bottom.

Click "save VBIOS" to save your original bios.

Clcik "flash VBIOS", point to your required rom and click OK.

You will need to restart your PC, and job done.

Got nothing to do with nvflash.

Maybe I should uninstall it perhaps

It;s been a while since I flashed, and can't remember. Maybe it uses nvflash under the bonnet.

I would uninstall nvflash (I didn't have it installed), try it again, and just follow the prompts to flash.
 
The bios you want http://www.overclock.net/attachments/20373 you may need to log in.

NV Flash Tools for Windows -

nvflash_windows_5.134.0.1.zip 403k .zip file

Instructions for flashing bios -

Unpack the zip file above and the bios you want into a folder on you c drive called classified. Then while in that folder right click in an empty space and select "open command window here" then procedd with the unlock command below and the rest of the commands as needed.

nvflash --protectoff

nvflash -4 -5 -6 biosname.rom

You might have to hit "y" twice. Once it says completed reboot. You might also have to reinstall drivers depending on bios.

Flashing with 2 cards installed -

nvflash -i0 -4 -5 -6 biosname.rom - (This is for card #1)

nvflash -i1 -4 -5 -6 biosname.rom - (This is for card #2)
