Thank you very much, just tried these and for the first time since buying the card I've been able to overclock the core and run benchmarks without it crashing.
 
Back at stock core speeds it's looking very stable so far (running with the 314.22 drivers), but need more testing with games to be sure.
 

i downloaded and installed the current 4gb ftw bios .5C but when complete both of my cards list it as version .4B
 
whats up with that?

hmm...i havent AFTER and checked again...i will do tonight.

well, it does state .5C for both after turning my machine on today...
 
good to go.

im getting DX11 errors now and lockups alt-tabbing in and out of BF3...

Updated all 3 to this bios...I can now overclock HIGHER and stable in Bf3 than previously. Lower clocks used to get me an inevitable pc lockup. I don't know what this bios update did, but it did a lot of good for me!

That's great.  Since I didn't get more than a few responses to my last post here, I decided to just go ahead and update mine.  I was hoping for something like you described, but no luck.  Honestly, I see no difference in anything in comparison to the last update (4c).  I tried running Valley & Heaven benchmarks.  Both ran as stable as before with my max OC's and when I tried OC'ing to the next 13mhz increment on the core, it crashed just as with version 4c.  Then I played Crysis3 awhile to see if I would see any differences in how the game played or in FPS, but no difference.  Oh well...

I'm running the newest drivers (314.22), which are you using? I know all systems are different, but I'm eliminating a lot of non-essential background programs this weekend too, so maybe that has something to do with my jump in performance also?

I tried the latest whql driver when 1st released, but I actually lost a little performance in Crysis3 which is the game I've been playing the most recently.  So I went back to beta driver 314.14 which I found to be the best so far.  As far as non-essential's running in the background, yes, if you had a lot of that going on and now you don't, that really could help you out as far a performance increase and a more stable & higher OC on your cards.  I always do run bare bones background apps so could be why I see no difference.  Thanks for your comments...

So how do you know if you need this update and what is in the compatibility list. And what stability did they improve

I have a problem with my monitor going to sleep so was asking what the fixes were for. But they should have a list of the fixes and improvments.

Terrible firmware update for me.

Flashed my card using the instructions given by EVGA, everything went smoothly, rebooted, played around ~1hr of BF3, closed BF3, started reading some emails, opened a Youtube video then all of the sudden... Boom! monitor went black, sound froze so it must have been a hard lock/BSOD/etc (I didn't get a picture of the error because for some reason when using the DVI-D port of my GTX 670 FTW [My BenQ monitor runs at 144Hz] I get no signal from Windows BSODs, my motherboard's POST Screen, etc, but that's a different issue).

Either way, I pressed the reset button, went into Windows, and right when I was searching for Event Viewer to see what went on, I got the same thing, screen went black, PC crashed again, etc, this went on for about 2 more reboots.

I powered off the PC completely after that, 6 hours later (GF came by my house so I couldn't perform more tests right away), I booted my PC, Windows message showed up saying that Windows didn't close correctly blah blah, clicked Ok or something that made me restart the computer, and then boom, screen went black again, this time with a No Signal message from my Monitor.

So right after that, I decided to try the iGPU from my 2500K to see if this was related to the GTX 670 or something else.

Enabled the iGPU in the UEFI, switched the DVI-D cable to the onboard DVI output, rebooted, and then Windows booted up perfectly, It's been running for over ~1hr without an issue, resolution is crap but that's because I don't have any Intel HD drivers installed.

So my question is: How do I fix this? will I have to downgrade to the previous Firmware? (I've never done this before so I would need all the help as possible), RMA the card? what are my options here?

Thanks in advanced fellas.

Until JacobF says its a must have on our GPU then I would go experimenting with it knowing that warranty will not be a problem, but like most people would say If it ain't broken why fix it? My (2X) 670GTX 4GB SLI have different Firmware
1st > Older GPU Firmware I Updated to 80.04.4B.00.70 < 
2nd >Newer GPU I purchase came with 80.04.4B.00.71 <
I said to my self ahh another updated Firmware!? Yet there were no Firmware 80.04.4B.00.71 added on forum in order to update my older GPU again? so I left as is & have no issues what so ever to this date, keep in mind others were having issues with Firmware 80.04.4B.00.70< It's like a Firmware gamble it works for some & it doesn't for others, I personally don't have time or money to gamble with PC parts if its not a necessity why bother? to feel better cause its up to date?
 
I know the stress I hope those having issues get things back to normal working conditions, Good Luck

Ive tried to run the firmware update for my 670 4gb sc+. it runs a few secs then stops. Isnt working for me. Anyone know why

Is your 670 Oc'd above the factory OC?  If so, set to default and then close the program before the flash.  Also close any other monitoring software you might be using before flashing.  Beyond that, it should work.  I assume that you selected the correct bios for your specific card.

Improvement indeed!!! Seeing a higher overall power target in most benchmarks(133%-140%), as well as better overclocks-- 1335mhz core now. I was using the first bios flash prior to this, not the 4b, the 4b caused instability for me.

Dumb question......what is the difference between the regular bios and the uefi bios??
