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

Thanks.

You have FTW bios in the OP! Primary and secondary! wink.gif http://www.overclock.net/t/1393791/official-nvidia-gtx-780-owners-club/0_100

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 same 780 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.


From one of my articles:

"An 8+2 phase system may not necessarily provide any more current than a 6+1 phase if the amount of amperage capacity through out the VRM system is the same; however, the 8+2 phase system would still do so with more efficiency, stability, and with less heat output.
However, as a practical consideration, many VRMs with more phases can supply more power. I mean, assuming you want to output 64A, it's usually cheaper to use sixteen 8A transistors than four 32A transistors. So more phases makes it cheaper to make the VRM more powerful (usually). So a VRM with fewer phases will often (but NOT ALWAYS) be less powerful, since making it more powerful is more expensive."


But cooling has always a word to say in the matter! thumb.gif

Gonna flash em' with the skyn3t BIOS this weekend and see what they can do.


My asus a great OCer 1320/7000 at 1.2 .... let me know how high yours goes

Very beautifully
I'm waiting for further information from overclocking.
Good luck.

AB beta 18 seems to report different voltages in the monitoring graph than what I set it too.

But my OC profiles seem to still be stable even though the voltage is reporting 0.05 v less.

Does anyone know anything about this.

well , since the Kepler BIOS Tweaker 1.27 is out and you can modify the voltage in it , i had to redo the default bios cus the ram can not be OCed in sky3nt bios .
now i have actually a better working bios for my 780 Gaming exactly the same as skyn3t but Overclock-able Ram .

Hey guys is EVGA the only company that makes Backplates for reference Gtx 780s?
post #17640 of 24915
So is it possible to go over 1.212v on ASUS 780 DCII with any softmod only? ASP1212 = CHL8318 and that unlock works for it too?
