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

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.

with stock bios and stock cooling, what freq should a 'good' Titan card get (only with precision x +38mv, no voltage hack. Push GPU only, not overclocking Mem)? 1175Mhz?

1200Mhz seems to be possible for a good card and 1180 for a not so good card. Mine would sit at 1180(ish) with the +38 in benching but that wasn't stable for gaming.

I have seen cards reach 1380Mhz on Valley with as little as 1.3V, so it seriously did make my Titan look poo.

what is the max GPU freq record for titan at this moment with all kinds of hacks?

8 Pack can tell you that.

Sorry, no idea.

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

Let me take a look later today, it may be possible to enable boost state with a slightly tweaked BIOS, failing that I'm almost positive I could change the static 3d clock speed to what ever you desire.

Greg, I've been benching (as you know) with 1300mV set in AB but on GPU-Z it's showing max VDDC of 1.15v... is this right?

Yer, the only tool that reads the correct voltage is Afterburner.

I can change the main clock to 1.3Ghz instead of default but it then causes voltage to stay at a continuous 1.212v

If you could enable boost on my BIOS that would be awesome...

1.3Ghz base + boost would rock

OK thanks, should I 'Force constant voltage'?

No need. It will drop clocks when on desktop/web browsing to idle and drop volts as well. If you force constant voltage, it will lock those volts to 1.3V or whatever you have them set to in Afterburner.

Ah right ok thanks.

Boost states appear completely removed from Skynets' bioses.

Why do you want boost back anyhow?

Because I want to make sure my card is being used to the max.

Although it's clocked at 1.3Ghz there's no doubt in my mind that if it had boost capability it could potentially boost even higher.

You could set the boost to what ever you like, it will still crash all the same. If its not stable above 1300mhz, having the card boost over that isn't going to help in the slightest.

Greg, instead of me trying to imitate or better my factory overclock on my card I'm gonna revert back to the original BIOS. Am I right in thinking I can just do this bit

Press and hold shift and right mouse click the nvflash folder and select 'open command window here'

If using a 780/780Ti:
next type nvflash -4 -5 -6 skynet-3A-SC-rev3-941.rom and hit enter (Or any of the corresponding names that fit your card)

But type nvflash -4 -5 -6 GK110.rom

As I saved the original BIOS as GK110

Edit: Ah this is too easy

Job done!

Why can't I get the second file to appear in the profiles folder in Afterburner?

I followed the instructions exactly... Using beta 17... Do I need to use another version of AB to get it to work?

Did you delete the profile b4 adding the lines of text - also did you close down AB?

I did as the guide said, install afterburner but don't start it and the file wasn't there.

So I started afterburner in hope the file would be there and nothing...
