I'm wondering how flashing custom bios would work with the warranty.  
 
A couple days ago a member on a different forum posted custom bios for many 670/680 cards that allows the voltage to be increased to 1.2120 without the need for a hardware mod.  Basically accomplishing the same thing Evbot can do for Classified cards. 
 
I was thinking about attempting this with one of my 670 FTWs but I wanted to see if it voids the warranty.  Would it be similar to installing a customer cooler? Meaning if put back to it's original state prior to an RMA then it's OK? 

If it doesn't void the warranty that would be really sweet, but I can't imagine how it wouldn't void it if EVGA knew it was installed. I do not know the answer but would be really interested in trying it if it didn't void the warranty!

If you try to raise voltage on your 680, an nVidia rep will hunt you down and eliminate you. They feel that strongly about having an unnecessary amount of power over your graphics.
 

The EVBot will allow a higher voltage limit, and works for more than GPU voltage.

PEXVDD2 PCIe Voltage #2

I'm not too worried about bricking it.  I know it's a possibility but I've done it in the past and it's not hard.  But Murphy likes come around when he's not welcome. I'm not even 100% sure I'll even both with it but wanted to have the info beforehand. 

Hopfully and EVGA rep will chime in. I'd understand them not honoring it on a brick.  But if the card still works and has issues unrelated to a bios flash I'd hope they'd be willing to replace it.

I already planned for this with a big "ATI Inside" sticker on the door. But incase that doesn't work, there's bucket of marbles by the door and vegetable oil on the hallway floor. :p

Flashing a BIOS not provided directly from EVGA would fall under modifications:

• The product must be returned to EVGA in the original factory configuration and condition. All aftermarket modifications must be reversed before sending in the product for replacement.

Meaning as long as you revert to the original bios before sending it in, it's fine? (provided you can do that with the card that needs an rma)

Great, thanks for the response.

hmmmm, it was my understanding that the voltage is "hardware" locked.  Only 3 cards contain the needed hardware mod to allow you to adjust it...  Lightning, Classified, and a 670 PE from MSI.  The Asus DC II need physical modification I believe.  The rest of them?  You need to cut the circuit board and solder some wires to get a higher voltage pass 1.175.  Are you saying that is no longer the case?  Someone figure out a way to bypass the "hardware" lock?  I thought that's impossible.

 
The way I understand it the hardware limit is at 1.2120 but the bios lock it at 1.175.  Which is why the 680 Classified can use EVbot to raise from the bios limit to the hardware limit.  The modified bios ditch the bios limit.

Save the -Original- BIOS before flashing 
*the first rule of BIOS flashing, is you do NOT talk about BIOS flashing 
  
Upon any warrenty return to EVGA, the -original BIOS must be -on the card- 
If for ANY reason you attempt to return a card to EVGA without the original BIOS, it will be returned to you -its warrenty void- 
  
*Personally I think that such voltage modded BIOS for the 600 series is ill-advised, unless you can afford to throw it in the trash and buy a replacement. If you can afford it, mod away 

 
I understand it needs to be on the card when it's returned.  If it bricks then it's an SOL situation. 
 
There's a massive amount of people over on OCN that have already tried it and have had success with it.  The average seems to be 50mhz+.  Obviously not a huge but a nice boost none the less. 

I would love to do it just for the 100% fan speed. The noise wouldn't bother me since I wear headphones and can't hear a single thing with them on.

One does not simply "use evbot" on a 670.

 
Of course not, but the OP specifically mentioned the Classified and EVBot.

He mentioned it, but no questions were posed about it specifically. He said he has a 670, not a classified. His question was:

Sheesh, Andrew! lol I was merely trying to correct the slight error made in this statement:
