Or you need a custom fan profile the factory fan profile is normally to lower side to keep the card quiet as possible.

My 3770k's currently housed inside an Antec Twelve Hundred.. the big ones. And while I used to have a lot of drives in it.. I now have just 3 mechanical drives near the top and 2 SSD's, so about 80% of the front 3 x 120mm intake fans are almost all open now, and the side intake fan.. and it has the big like 240mm exhaust up top. It gets.. excellent airflow.

And I would show you my fan profile but my 3770k's dead in the water right now, ram failure yesterday (I have more on order). But the basic jist of it is I have a rather aggressive fan profile with it hitting 100% fans at 80c, and near 85% - 90% at 75c. Loud but.. I usually have a window air conditioner going and games turned up over that so I hardly notice it (Texas gets -HOT!-).

I have the PNY GTX 770 2GB edition and am looking for a custom bios so I can increase the voltage. I want to push this card as far as possible, it is only getting to 80c max with my current highest overclock. I can't increase the core clock any more without driver crashes and the voltage is locked.

Anyone know of any bios that will work with this card, or any guides for modifying the bios myself? Thanks

First off a little warning. -DO NOT- under any circumstances download any other bios from anywhere on the internet and flash it to your card. It won't work and you run a high risk of permanently frying it.

The 100% -SAFE- way to do it is to extract the existing bios from your card with gpu-z, upload it somewhere and post it here or somewhere else on overclock.net and ask someone that has experience with it to kindly modify it for you. Then re-flash their modified bios back to your card.

Keep a backup of your existing bios somewhere, and be prepared to either use another video card or second computer to plug in or "slave" your card to, to re-flash back your original bios, just in case.

I don't know any good threads off hand to post to.. I used to know one but lost it. Maybe someone in this thread could help you (I have no experience editing bioses myself, or not enough to do it for someone else).

Alright, well, I used a voltage editor to supposedly change the voltage limit to +.1v (1.312 instead of 1.212). When I go into MSI afterburner, I have the whole 100mV range to play with, but no matter what I do, the voltage is still reading 1.212v. Is the sensor in GPU-Z accurate? I'm assuming it didn't really unlock the voltage on the card. Thoughts? I will give more information on what I changed in the bios tomorrow, if anyone cares.

That's a thing with the 700 series. The voltage is probably actually there and set up higher, but most 700 series / kepler cards don't report above 1.212v to software monitoring, even if the voltage is higher.

No offense but I'd say it's equally likely that the bios mod simply didn't accomplish allowing the additional voltage ... than it is because the true voltage is being misreported ... JMHO.

Raj, are you able to OC higher after the mod? That's the most important question I'd say wink.gif

One last thing ... try doing the overvolting with the EVGA Precision tool, see if you can get that extra .1V to 'show up' in the graphs there. Overvolting is the ONE arena where different OC'ing tools can show different results. Everything ELSE but voltage control (overclocking, fan profiles, etc) is done via the Driver, so the popular tools all work the same in that regard.

Not so with voltage control functionality ...

I know with my hotwire mod no software monitoring tool can read the voltage above 1.212v, I have to check voltage at a hardware level

But yes can you OC more after the mod that is the most important factor thumb.gif

I wasn't really able to overclock higher even after adding a 100mV offset. Maybe a 20-30mhz increase, but I didn't get to do enough stress testing to determine if it were actually more stable.

If it were actually overvolting by .1v, I would expect a 50mhz increase easy.

The "overvolt" option on EVGA precision seems to be disabled now. I can't select it, and sliding the slider just goes between o-1212mV.

Where do I put the leads of a multimeter to test the voltage manually?

Thanks.

My GTX 770 is "EVGA GTX 770 SuperClocked Dual" and I can manually set it to 1.300v and I got a minor overclock +10 Mhz more from it. I can set this with EVGA PrecisionX to 1.300v, and so I know in my mind it is that way but all of the monitoring software.. afterburner, nvidia inspector, even the monitoring tool inside PrecisionX all report 1.212v still. I was under the impression from a good friend of mine "djthrottleboi" a while back that nvidia was attempting to "lock down" the voltage with all versions of all GTX 700 series cards and not allow anyone to ever change the voltage for any reason what so ever, not with software not with bios. BUT there were some vendors (EVGA, GALAXY, ZOTAC) maybe a few others that "went against nvidia's mandate" and allowed voltage changes with some select models (EVGA 770 Classified, EVGA 770 KINGPIN, Galaxy hall of fame, Zotac AMP!), etc and these companies are the ones that allowed and reported voltage increases. I seemed to remember also EVGA got in a lot of "hot water" with nvidia for doing this and such.

So anyway supposedly this "is a thing" and most 770's (not all) both (mostly) lock at 1.212v, don't allow it to be changed at all, and only report that value even if the voltage does go over.

The only way to reliably increase voltage and monitor it is with soldering to the cards and "hard mods" for voltage and monitor it with a volt meter.

EVGA Classified 770's come with a connection to the EEVBOT that both hard modifies voltages and provides real-time voltage read out to their custom device's LCD panel, and offers a direct connection with leads to use your own volt meter that plugs into the cards.. because that's the only way to read it reliably with the 700 series.

Highest core clock I can get is just over 1200mhz without instability. How does this compare to most overclocks?

And does anyone know where the leads go to test the actual voltage with a meter?

Thanks
