Hello,
I'm new here and pretty new to EVGA but I seem to have had no such luck with this bios update.
I flashed my 4GB 670 GTX SC yesterday and the flash completed successfully.  I rebooted and was playing games like Anno 2070, Warcraft, Rage, CS:GO all day and the card performed great.
One thing I did notice is that using Adaptive Vsync from the control panel no longer worked e.g. WoW and CS GO were running at 150+fps and maxing out my card to 99% of it's usage.  Enabling Vsync in game fixed these issues though.
Then around 8 hours after flash I went to launch CS:GO and my two screens blacked out and machine froze - next reboot all I get is what you'll see in the screenshots.
 
I can't find how to get a factory bios for this card officially through EVGA forums.  I don't want to deal with any 3rd party sites. I've created a support ticket too - really hope I don't have to RMA this card and be without. :(
 
I can get into Safemode and from here uninstall the nvidia drivers.  This allows me to log into Windows and can apply the flash, however after rebooting I can only get back in via Safemode because the drivers install for the display adapter automatically.
 

Anyone know where I can get my hands on a stock firmware for an EVGA 4GB 670 GTX SC before I send it off for RMA?  I just want to try once more.
 
I don't want to unlock clock speeds or fan usage, just revert it back to normal.

Just got my new 670 FTW, played everything well, except when i started something really demanding like crysis 2 on ultra or skyrim 2 with all eye candy. All of a sudden, some minutes into the game, the screen goes black. The game crashes but the sound goes on. I have to quit the game via task manager then.
 
Updated this BIOS and now i can play about one hour before this happens. The problem is still not completely gone though... any ideas? Do i have a defective unit?

I just got my 670 today, and started Skyrim up and played about 5 mins myself before I got artifacting and crashed.  I'm still looking for answers myself.  I'm using the latest driver 9.18.13.602. 
 
Like others I updated the firmware to this 80.04.31.00.70 and now boots with artifacts on splash screen and crashes after the Windows boot and loops.  I had to re install 285 to get into windows.
 
 
 

I have one of the PNs mentioned specifically 020-P4-2670-KR. I also am attempting to install it in a Dell XPS 8300, one of the reasons for the firmware update.
 
I have now spent two days or so installing and uninstalling the board. I attempted the install according to the eliminate all previous graphic drivers, start clean approach, and then get a black screen on start-up. I read some more in the forums and then attempt another install which means I must uninstall the 670, re-install my old graphics card, make some recommended changes to the audio programs, etc., uninstall my old graphics card and drivers again, to then re-install the 670 and end up with a black screen again. I have been through this exercise probably 8 times trying various recommendations over the last two days.
 
Now we are talking about a firmware update and want to try that, but I am unsure how to run a firmware update with the 670 installed and looking at a black screen. This has been an exercise on installing a graphics card and making changes to the system while blind. Any help would be greatly appreciated as at this point I am losing my will to live. LOL

Just got the new card this afternoon and thankfully the card was already flashed with the updated VBIOS. I'm happy to report that it runs like a CHAMP on my xps 8300. Thank you eVGA, you have quickly earned my respect for helping out the "little guy" and BIG thumbs down to Dell, they have eternally lost my support...never again will I buy a PC from those scumbags. eVGA has my support!
 
thanks,
Jeremy

The firmware did well for me. I noticed a tad of performance loss but to a gain of stability. You should be okay Madogre essentially the 670 FTW LE architecture is the same as the KR version that I use. I'm not exactly sure what is different on the LE, I just saw they a were a few bucks cheaper than mine.
306.02 driver-
The 306.02 driver is garbage, if it was worthy, a WHQL version of the 306.02 beta would of already launched.... I play about 30 different Dx9/DX11 games and so far the 304.79 is the best yet. First game I played after installing the 306.02 driver (Test Drive 2 Unlimited) crashed within first 3 mins and prior to that I noticed stuttering. No problems with 304.79, although I would like to see some better SLI support or increase in SLI performance. 

I would-

With all the posts about artifacting and black screens, I will wait for a more stable firmware update.  Nothing wrong with my card as is right now anyways.

The same thing is happening to one (or both) of my cards now too.  I flashed the firmware update last weekend and played a bit.  All seemed well.  Next time I boot it up and start playing BF3 it crashes to black screen, but the sounds and all other windows sounds goes on.  I can't even get to the task manager. 
 
The cards ran flawlessly until I flashed the firmware.  I was given a successful install on both.  Now this.  It only occurs in SLi.  When I run benchmarks in single card mode, no crash.  When I enable SLi it even crashes in a browser.  I've installed the newest beta drivers from Nvidia (306.02) same problem.  Not a driver issue.  It is a bad firmware install.

EVGA can you please advise?

EVGA, are you guys planning on releasing a more updated stable firmware patch to fix those issues mentioned earlier in this thread?  Just wondering if I should take a chance with this update or wait for a newer more stable version.

Thank you for the update Jacob! I followed the installation instructions and the install went great. Success the first attempt and I'm up to date. w00t w00t

@Chuck_IV, completely agree with you on that!

The problem with your card (most likely) was the firmware.  I think v80.04.31 has some bugs.  Not working in SLi for some user is an obvious one.  I flashed my firmware 2 weeks ago and used SLi for short time after that.  All seemed well.  After I shut the system down completely, and fired it back up again is when the crashing began.  It wont even open a browser in SLi before it crashes to a black screen.  All of which I attribute to the firmware flash.  My system was 100% stable before the flash.  I tested it for hours using 3DMark 11, 3DMark Vantage, Heaven benchmark 2.1 and 3.0, plus countless hours of BF3 (settings @ ultra), Dues Ex: HR, and Diablo 3.  So, I know the problem lies with the flash.

Wait, so the firmware just made everything worse ?
 
I was thinking in taking another gtx 670 ftw, in case that one (3rd) also came with problems, I'd try the firmware.
 
I think that is a no for this, right ?
 
Thanks.
