Well you haven't gone into depth as to why you're disappointed.
 
What is the problem exactly?

well thats good, I know about the other bios... just its been a while since I have done it and I can find any good guilds to flashing... if anyone has a nvflash walkthroughs for forgetful people that would be nice , lol 
 
 
merry christmas to all

i have similar problem with 780 classi. i cant overclock over 90mhz offset. that means that i barely get 1200mhz on boost clock. i dont know if that happened from ASIC 62.3%. . Matthmarro sorry i cant replay ur pm cause i have only 2 post on evga forums.

i did all oc steps i read. switch Ln2 bios , power target 115% temp target 95C overvoltage on +63mv. first checked core clock increasing 13mhz per time till the driver crush. i had potential for my classy but now i am really disappointed. :(

Matthmarro send me your email pls

I'm very disappointed.
I already bought two EK classy water blocks and going to buy two 780ti classified... 
Is it easy to change / replace / update bios or do i need to flash the new bios?

When the firmware gets released you will have to flash the bios...

This card has two bios. Do I need to flash them separately?
 
 

Just flash the ln2 bios... Leave the other stock..

I'm disappointed with my 780ti Classified as well. So far it's been a dud for overclocking. Barely 1200 MHZ boost and almost nothing on the memory (artifacts at +200) The stock voltage boost doesn't help much either, it only increase's the time before a crash. Funny thing is the best OC I've been able to stabilize (1232) in the Heaven benchmark has been at stock voltage. Once I go any further it will crash halfway through, occasionally it will complete a run but will crash part way through the second run, additional voltage does nothing to stabilize it.  
I have also used the  Ln2 bios, with power target at 115%, temp target 95C over voltage on +75mv. I can't believe a card marketed so heavily toward over clocking overclocks so poorly. If this were a reference card I wouldn't be complaining, just luck of the draw, but all classified's should perform above average. I'm really hoping the new bios will help with these issues.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

For all nervous about flashing BIOS themselves:
 
skyn3t has a .bat that more-or-less does it for you.
 
Check out the 780 owners club at oc.net.
 
 

Wow didnt expect so many people to be unhappy with the classi. So alot of people have issues with overclocking? A so called overclocking card being horrible at overclocking? Bluh. Guess they are only giving the good chips to the kingpin and neglecting the classified? I guess we should of seen it coming when they announced the kingpin

yeah, skyn3t took down his 780ti classy bios

What happened?

Out of the years I been building computers, overclocking and enjoying hardware. I've come to learn that EVGA firmware/BIOS are not always trustworthy for the investment. I'm really thinking of switching to ASUS or MSI for video cards and motherboards. Really was cured from buying a EVGA motherboards. In fact, it is hard to trust any manufacturer these days. 

Wonder why they don't hire that guy that made the new bios?  seems to be doing a better job than their employees.  I think his handle is skynet?  Anyways, not comfortable in using his bios for the fear of no warranty lol.

This is why the MSI Lighting is looking like a great option. 

as far as I know its a classy issue, but my card wont ever go above 1.174.... so who knows... I have faith in EVGA though

+++ power. Actually, they promised "unbelievable overclocking potential".

It is unbelievable.

But the card is truly a work of art. I absolutely love mine. It romps stock and is quiet with good temps. Having a good time with it.
