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

The nvflash won't work, it's asking for a newer version - and every version I try say incompatible with 64 bit windows. :(

It also say; 'Warning: Firmware image Board ID (E231) does not match adapter Board ID (E613).

Is this something I should heed?

Checking for matches between display adapter(s) and image(s)...

Adapter: D15U-50 (10DE,1004,3842,2784) H:--:NRM B:02,PCI,D:00,F:00

WARNING: Firmware image PCI Subsystem ID (3842.0781)

*** WARNING: Overriding the Board ID can be very dangerous. ***
Upgrading to an image with the wrong Board ID can render the video card
unusable.
Overriding the Board ID is only needed for extreme circumstances.
A mismatched Board ID almost always means the wrong firmware image is being
used for the specific video card.
Are you sure you want to continue?
Type "YES" to confirm (all caps):
YES

Current - Version:80.10.3A.00.80 ID:10DE:1004:3842:2784

Gregster and myself plus many others have used this guys guides without issue,

as always there is a risk :(

Yer seems my NVflash is out of date now. As for the warnings...Man up :D

lol

No offense but someone who can splash out on several titans probably isn't too bothered if a flash goes wrong. £400 is a lot to me :p

....although the flash went fine from what I can tell. I have voltage control up to 1.3 and gpu-z reporting that it's morphed from MSI to EVGA, and I can now set accurate clocks instead of having to guess what boost will be.
 
Quick question for you all. My overclock is still playing nice but I want a slightly higher voltage 24/7 being on water and all :D

I have been reading about 'the cold boot fix' however I was not able to find details of this? Ideally I don't want to have to open ZawarudoABHack every time I reboot :)

Any ideas experts?
 
I only ever used the zawarudo hack when I was benching hard. For 24/7, I use the 1.3V available in AB. I like that my card no longer boosts and throttles and keeps a constant clock.

Only use the Zawarudo hack if you want to go over 1.3V, the other stuff for normal day to day clocks.

For arguments sake if I wanted to run 1.32 24/7 are you aware of the cold boot fix? Temps never go over 50 at 1.3v.

For sure I am aware and only seen it happen to one guy but if you are unsure, don't do it or you don't have another GPU, don't do it. The only way to recover it is with an IGPU or another GPU.

If you do have another GPU, here is the fix if you do run into problems and this pretty much is the same for all who have a bad crash. I shamelessly nicked this from another site :)

If you have a cold boot black screen after flash just follow thos step below to get you up and running
1 - Shutdown pc remove the PSU power cable
2 - Remove both 8pin cable from GPU
3 - Press power button in the rig to discharge the PSU and the rest of power in the circuit board
4 - Wait about a minute ( two minutes recommended )
5 - Plug back the PSU power cable
6 - Do not plug back the twi 8pin power cable to GPU.
7 - Turn on PC boot into UEFI or Bios and enable IGPU ( GPU integrated in the CPU ) exit and save
8 - Boot into windows and wait just a bit to drivers load
9 - Open GPU-Z you will see the GTX there but you cannot use it yet because it is only powered my PCI-E only
10 - Open nvflash and falsh back to working bios or vBios and have fun.

Make sure you follow the instructions perfectly before trying to flash the BIOS again. I just flashed my 780 Classified a week ago and had no issues.

The only difference is with another GPU, you would plug that into the top slot and plug the bad flashed GPU into the 2nd PCI-E slot and everything else is the same except number 7, which you shouoldn't need to do.
 
Thanks for coming back to me Greg. Perhaps my understanding of the cold boot fix is incorrect however users on the overclock forums are refering to it when other users are specifically asking for a way to ensure that their chosen voltage (1.32 in my case) is maintained after: after burner is closed, or they reboot.

Thanks for the tip above though, lets hope I don't have to use it.
 
What OC are you guys getting with the Titan.

Having a play with mine and it seems to need more voltage to push it further.
It crashes out even with the card running under 70c on air while benchmarking.

Ahhhh I see what you mean. Sorry, it was late and was a long long day :D I am not sure what the answer is to that. Draining all power to the system should do it or reflashing back if it happens to you. I did a flash and had the same thing on my Titan, where it was locked at 1.3V. I just reflashed it and it was sorted but not 100% on the Classy. Maybe someone here who has one can confirm/deny if they have had any issues and if so how they sorted it.

My Air clocks with the bog standard BIOS was around 1150Mhz (Not game stable (pretty poor clocker)). I didn't try the AB hack till I put my card under water and now I sit at 1163Mhz at 1.212V and can sit at 1250Mhz @ 1.27V. I prefer to only go just over the 1.2 though, as I wouldn't want to ruin the life of my card and only go big on volts when I am doing a quick bench run. These things are fast enough already :D
 
Just a heads up, skyn3t has added lots of bios files for custom pcb variant 780's, just flashed my phantoms with the jetstream bios (same pcb) & all is well, screens to follow!!
