EVGA tech support is the best.  RMA process has begun for my malfunctioning card.  My best guess is the firmware flash may of exposed a weakness/defect in the card itself.  It would explain why only card went bad.
 
I wouldn't flash until someone from EVGA says something official, or updates the firmware.  I only had to mention that I flashed the firmware and then the problems started and I was issued an ticket number for RMA. 
 
Still...this is why I buy EVGA products.  They stand beside their products, answer questions, and replace malfunctioning parts...as long as you register your products.

Could someone clarify what exactly this changed, I've read this thread few times but there seems to be no consensus.
 
My 670 4GB SC+ came with this firmware so I know of no other state but I do know that games (such as BF3) and 3DMark11 push the power up to 125% levels (seems little excessive?). The power target I can set is 122% of course.
 
Am I being thorttled early by this firmware (note: temps are fine)?

I believe it corrected some stability issues with overclocks and improved performance in Dell 8300 desktops.

I saw the 8300 fix which was good news for them but I'm running into a weird issue.
 
My 1st card has that so called keppler boost of 130. Running it stock on Heaven you can see it throttling between 1163 and 1176 (max) and down to 1150 during the dragon part.
 
My 2nd card is has crap keppler boost of 52/65 (it goes to 65 after x amount of time under load for some reason but will not start there). If I OC this card to match my 1st card it remains stable all throughout the run - it has the same firmware but uses less power at those same clocks.
 
Temps are fine and below 70 so all I can think of is the 1st card is throttled by TDP already.

I didn't have any problem flashing this new firmware to my GTX 670 FTW. Nothing changed really, except for some improvements.

Has anyone ran OC Scanner just when running stock and if yes what clocks do you see?
 
For example - without keppler boost - the 670 4GB SC+ is meant to get 1046Mhz. I'm at 1005Mhz - 1019Mhz with power target set to 122% and temps at 65 degrees.
 
So if temps are under control is TDP simply too low to cope with this?
 
Above was using "Furry EVGA" stress test. If I choose "Ferry-Tessy Donut" then it's even worse instantly and it's down at 966Mhz because it's been down-volted hard.

Bump.
 
Is this BIOS / Firmware useless or are my cards defective? Today I ran Heaven on the 'better' card and even with power setting at 120% the thing throttles down a notch 17% of the run.
 
How is that stability - that's throttling @ stock.
 
add: for those playing at home, the card comes with overall boost (no OC) @ 1176Mhz. So obviously nothing dramatic.
 
add2: this is comparing against my 2nd card which is worse (boost point of view). It comes with a beastly boost of 52 and then for some reason up's itself to 65 when it reaches the dragon part (so total boost of 1110Mhz with no OC). This card does not throttle and even after putting +66 core offset stays stable at those volts / clocks.
 
Only reason I'm posting here instead of creating a thread is because I would love to see the previous BIOS made available so people like myself can test it (I never had the opportunity).

welcome to our site I hope you will enjoy accessing forums.

EVGA GeForce GTX 670 Firmware Update v80.04.31

Q. What are the changes in this new firmware?

• Improved stability
• Improved compatibility with DELL XPS 8300 systems

 
Q. Do I need to reapply this update every time I update a driver or reinstall the O.S.?
A. This update is attached to the card, no matter where it goes. If you update the driver, the EVGA firmware update is still applied.

Q. How can I tell what version I firmware I currently have?
A. There are multiple ways to do this, one way is to right click on desktop and go to NVIDIA control panel. Click on Help, then System Information. Scroll to the bottom of the Details window and it will show your "Video BIOS version". It will be listed as EXAMPLE: 80.04.31.00.72. The numbers in bold identify the version number.

Q. I just bought my card, will it have this updated firmware?
A. Chances are yes, as new firmware is release, new products shipping from EVGA will also have this firmware version applied.

You can either use precision and/or gpu-z
