I want to flash a new bios with risen TDP into my MSI GTX 780 Ti Gaming.
When I use nvflash, do I have to use the --updateuefi command? How can I know if a UEFI bios is flashed into my card by default?
Anything else to consider?
Thanks.

For Flashing:
If you are not familiar with Nvflash command Skyn3t has created this little tool to help anyone flash their BIOS easily. Just read the instructions, follow the steps, and you should be fine. Below is a quick screenshot to show how it looks like.

Thanks, but I already used nvflash via CLI. Simply gave it the path to the bios and that's it, nice tool.
Card isn't throttelt anymore, seems to be stable with 1275Mhz@1,175V. Overclocks like a dream compared to the three 290s I had before.

I added in the line with no luck on the beta 19 version. No luck. In fact now I can't even move the voltage slider in afterburner!

Am I missing something?

So there's no way to mod the voltage to the card without using the old version? I'm happy to mod the bios and boost the voltage I just don't know where to adjust it!



Also it should be noted that this specific card I have is based on a 680 GTX board layout. Don't know i that would cause any kinds if limitations. it is the NCP4206 chip on board and I've had some cards unlocked to 1.212 but this one is locked for some reason and I can't determine why...

Sounds like that is the issue. If it is just a rebranded 680, then you can't go past the 1.212v without hard modding(From what I have read about it)

This tool allowed me to lower memory clocks of an ASUS GTX 770 BIOS, which I later applied to my GTX 680! Now I get Boost 2.0 and all clocks are stable.

I hear that you should NOT be using the highest voltages because doing so will cause Boost to actually lower clocks... I was just wondering if I could further improve my GTX 680 to GTX 770 BIOS modding... GTX 680 max was 1.21v, but with GTX 770 BIOS I can go up to 1.312v! Is that dangerous? I will be getting GELID Icy Vision v2 for my GTX 680/770, which should bring the max load temperature under 72C using 1.21v. I am already getting 1300Mhz / 7000Mhz on 1.21v and stock cooler, so I can imagine how far I can push it with Icy Vision 2 cooler!

Does anyone know how exactly to edit driver .INF files for them to recognize my GTX 680 as GTX 770? When I placed GTX 770 name for GTX 680 ID in nv_disp.inf - drivers would not install... I also wonder why flashing GTX 680 to GTX 770 did not change the actual ID number..? Is it deeply engraved?

There are no benefits in flashing a 680 to a 770. 770 Uses different memory than 680 which probably isn't fully compatible with it's BIOS either. You can't go over 1.21 volts without modifying afterburner.

What are you talking about? My GTX 680 RAM runs 7000Mhz perfectly fine. Some people like me got lucky with RAM like that, but others did not. Still, those who did not, could've just used this BIOS editor and reduced GTX 770 BIOS memory clocks to whatever they wanted or to whatever their maximum memory overclock was. GTX 770 provides Boost 2.0, which prevents GPU OC downclocking when GPU temp reaches 70C. Boost 2.0 allows much higher than 70C before clocks are reduced. I could care less for 1.21v if it isn't working, but the rest is very worth it. Have you ever seen FPS variance between GTX 680 and GTX 770? Total and avg FPS are about the same, but GTX 680 has way more ups and downs, while GTX 770 stays smooth since it doesn't flip flop its clocks!
