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.

So, one can only assume that EVGA is aware of the firmware problem(s).  I know my system is completely disabled right now.  I have a $400.00+ plus card that is setting in my system that when enabled, crashes everything.  It wont even open a browser before it crashes.  Disable SLi and it is fine. 

When I get home later this week...I'm going to try and flash my card(s) individually and see if that corrects the problem.  I would however like suggestions and/or a link to download the previous firmware version.  My rig was running great before I flashed to the newest version. 

Trust me.  I will definitely wait before flashing again.  This is a total bust for me.  I'm not very happy right now.

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

I'm very surprised that EVGA doesn't make the previous firmwares available for download. Because there are potential unfound bugs in ANY program,  is exactly why they SHOULD make them available, so peolpe aren't left being SOL while the company figures out what went wrong.
 
I can't say I've had any issues yet, but I flashed late last night and only did minimal things and I also don't run SLI(which seems to be the problem).
 
Anyway, come on EVGA, make the old firmwares available.

@Chuck_IV, completely agree with you on that!

Hi,
 
Today I've sent my second gtx 670 ftw back to the store.
and I'm wondering if the problem is really the compatibility with some motherboards, in my case I've a maximus extreme IV gen 3 - P67, that is one of the luck ones, right?
 
I've the same problems the a lot of people with those cards are having ... BSOD, crashes, artefacts and all of that.
 
Now, is this a problem with the card or some driver, firmware update will solve it ?
 
Because if somebody could answer me that some update will solve this whole mess, I'd get another gtx 670 ftw and wait.
 
So please, help me on this matter.

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.

*update*
So, I removed the functioning card and tested the card that I thought was bad.  It is bad.  Apparently the flashed has seemingly malfunctioned the card.  When I test the card with the Heaven benchmark it crashes 5 or 6 seconds into the flyby and gives me this error "D3D 11 Appwindow:Swap():device removed" and "lDXGl swap chain: present device failed: device removed.
 
Just for fun I ran 3DMark:Vantage and was given this error:  (DXGl_Error_Device_Removed).  And of course the old stand by:  Nvidia drivers stopped responding.  Windows Kernal mode driver 301.42 stopped responding and has successfully recovered.

None of the errors were present before the "firmware" flash.  My machine was running perfectly.  I'm wishing I would of never of flashed my firmware now. 

DO NOT USE THIS FIRMWARE UPDATE.  It just isn't worth the risk.

Beginning RMA process.

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.

I wouldn't do it If I were you.  At least not until someone from EVGA says something official about it.  I know I have to RMA my product as of right now because of this flash.
