the problem with the default bios is the throttling cus of the power limit , it will always throttle down .
i tried to modify the power table the same as skyn3t bios and it worked fine after that . but the max volt wont go high than 1162.5v and i cant change that value cus its locked

this is the default one



and this is skyn3t


yes,the msi boost make me crazy,too.the boost of asus o. gb 670,660ti and the first msi 780 was more constantly.

i`ve experimented yesterday with it.the first 2 bios run incl. own powertarget tweaking by rail and vcore.but then i got a error after boot by the third bios.first desktop,then brown screen.then after reflash red screen,then orange screen.so go back to default.maybe system must set off new.

first i got 450-460w in heaven and constantly boost incl. 1,21v.but the boost run only when you take 1,21v by precision tool.for real 1,21v you must set 1,225v at the first 4 sliders.->1,225v to 1,225v.

for the biostools today you must have a diplom...at 670 you can`t save baseclock,boost and max boost what you want.it must the same differences like default.that`s sucks...

but i warn you to setting the same values as they were shown in picture.there is a gainward 780ti with 2x 8 pin.we have mostly 1x 6 pin and 1x8 pin.also is the 1.27 new and nobody knows where is the damageborder.

I still dont get why if I set boost clock to 1200mhz why does my card run games at 1267mhz then shouldn't it only boost to 1200 mhz ..

I'm using skyn3t's BIOS 80.80.21.00.39 on my Gigabyte GV-N780OC-3GD (rev. 2.0). No problems at all.
24/7 OC - 1293/6458

What voltage are you running at?

Use the Secondary BIOS in the zip for the FTW BIOS, it will allow the fan speed to go down to 29%. The stock primary BIOS had a minimum fan speed of 39% and the secondary had a minimum fan speed of 29%, that remains unchanged in the modded BIOS.

Hey guys, quick question.

Which bios do I use if I'm currently running 80.10.3C.00.80 on my GTX 780 FTW?

Thanks.

I'm looking at these two infrared images of the 780 Ti:

Gigabyte GeForce GTX 780 Ti WindForce 3X OC review - FLIR

EVGA GeForce GTX 780 Ti SC SuperClocked ACX Review - FLIR

I find it weird that the 8 phases on the gigabyte card are hotter than the 6 phases on the acx. They both have the same VRM setup on their 780 version of those models as well. Why is that? Because of cooler design? What's the point of more phases if they only get more hot?

Edit:
It can't be down to just phase count. The MSI 780 Ti has 6 phases and has the worst VRM temperatures of the bunch:
MSI GeForce GTX 780 Ti Gaming Review - FLIR
That FLIR image is hideous.

It seems that the conclusion from this is that EVGA's ACX cooler is really good at keeping the VRM cool.

Also, here are FLIR images of the reference board if you are curious: GeForce GTX 780 Ti review - FLIR
I wish the reviewer kept the thermal scale the same... and measured the same spots on different cards.
