How to over volt a Titan, a 780Ti or a 780 guide

Everything I've run this cooler on that's had VRM temp monitoring has shown the VRM to only be within a few degrees of the core at load.

But yea I'll keep an eye out :)

Yer, I was only going by a guy who is very good at overclocking on OCN.net (ftw420).

I feel I should update the OP to the latest tools :)
 
OP updated with the newer NVflash and also an overhaul on BIOS's and I have now included the 780Ti and BIOS's for those cards, as well as BIOS's for different 780's (Cheers Skyn3t).

BIOS's now included are:

(780) EVGA ACX - All reference cards - Gigabyte WFx3 - Gigabyte Ghz Ed - Twin Frozr 4 - EVGA SC Reference - Palit Jetstream - Palit Hall of Fame - Asus DCII

(780Ti) All reference cards - EVGA ACX - Asus - EVGA ACX SC - Gainward - Gigabyte - Inno3D - MSI - Palit - Zotac - Palit Jetstream.

Any probs, as always, let me know :)
 
A lot of penis touching going on here towards Skynet. I was able to dupe his BIOS from someone else's work within the editor. That's the glory of the internet, people share everything. :cool:

Cheers for updating the guide Greggers.

I wouldn't like to say yes or no in honesty but I would happily use 1.25V 24/7 under water. That gives me a little extra and enough to go over what I could normally for a stable overclock.

after reading your tutolial, it seems there are 4 steps.
first, flash mod bios, which allows constant 1.212v with BOOST-disabled.
second, hack MSI AB, which allows increasing volt further to 1.3V
third, remove LLC, which gives you extra 0.025V voltage.
finally, with Zawarudo's it allows set voltage to whatever you want to.

Am I right?
 
I knew that, the max GPU freq and max mem freq depends on the ASIC quality, when this sort of voltage hack has not been figured out.
Can I say, now with these over voltage tools, all cards with different ASIC (e.g. as low as less than 60%,. or as good as upto 80%) are able to run at same GPU freq and mem freq?

I think my guide makes it look more complicated than it actually is but I like pics when I am doing something for the first time and it is quite worrying, so I thought I would explain it as best I could and show what should be happening. so......

  1. Flash the card, which takes away the boost, stops thermal throttling and gives a constant 1.212V.
  2. Add 3 lines to MSI Afterburner Beta 16 Ven10 file
  3. If you are getting Vdroop (voltage drops, use the LLC fix
  4. If you want more voltage (not recommended), use Zawarudo's tool.

And that's it :)
 
Is there any custom BIOS's that have higher voltage, power draw but keep boost enabled?

Mines locked at 1.3Ghz but I reckon with boost it could go a little higher if needed

so it seems my understanding in last reply is correct:D

what is difference between ri3 and ri4 cards, what does ri3/4 mean?

Not that I am aware of and being honest, it is the boost that I dislike. I bench and see my clocks set at 1300Mhz for instance and with boost, you watch them go to 1320Mhz - 1260Mhz - 1340Mhz and never get a constant bench and I feel it doesn't give a stable overclock with it fluctuating like that all the time.

I like to set a clock and know if that is stable for gaming or stable for benching.
