1- Remove PGR100

4- For those who want to do OV without ASUS ROG MB.

a. Connect a variable resistor between OVG pin and Ground pin to over-voltage GPU voltage.
A 1.2Kohm resistor will over-voltage GPU to around 1.23V.
please make sure that you measure voltage in 3D mode while adjust variable resistor.

b. Connect a variable resistor between OVM pin and Ground pin to over-voltage Memory voltage.
A 5.5Kohm resistor will over-voltage Memory to around 1.7V.
A 1.5Kohm resistor will over-voltage Memory to around 2.0V. More than 2.0V is not recommend.

c. Connect a variable resistor between OVL pin and Ground pin to over-voltage PLL voltage.
A 11Kohm resistor will over-voltage PLL to around 1.1V.
A 4Kohm resistor will over-voltage PLL to around 1.2V. More than 1.2V is not recommend.

Wow...

So far I've;

Returned one Gigabyte WF because it had a faulty fan when I got it and it would not OC at all. I figured it would give me problems later so I paid the $15 restocking fee and went on my way.

I instead got an MSI Twinfrozr Gaming which fried itself within one week, I loved that card though so I gladly accepted another one. Both of the MSI's vere very average OC wise but that cooler is awesome so it was rather quiet and cool. That card is going to be used on my brothers build.

I then got myself an EVGA ACX SC which also was rather unimpressive at 1256 core and 7250 mem at 1.212 volts(exactly the same as the MSI but MUCH louder). I lived with it because I was sick of all the RMA's at this point but....it exploded with a loud crack so I sent it back for a replacement. This whole thing is now making me very angry as I've spent a ton of money on something that I've barely gotten to use.

Well so my new card arrives and I really don't feel like even looking at my computer which is now in pieces all over the place. You know how it gets, fans standing propped up everywhere and cables in a mess and everything feels dirty... I strap myself down with a sigh and decide I need to at least check if the thing is broken.

1315 core and 7600 mem at 1.212V , stock TIM! Granted it's very hot now but WOW! This card is a beast, I'm currently running it at 1200 core 7200 mem at 1.125V! At these settings it maxes out at 72C in Valley at about 65% fan speed which is rather...bearable tongue.gif It appears stable enough now but I've yet to test it for sure and I will MOST DEFINITELY be getting myself a Prolimatech MK-26 (http://www.caseking.de/shop/catalog/advanced_search_result.php?keywords=MK-26) for this card, it totally deserves it.

Wait, so the compatible resister only nets you 1.23v? After having to sweat blood nervously dicing with your PCB...I can get 1375 core on 1.212v. For the trouble....

...I'd rather just get a Classified biggrin.gif.

You need nerdsmiley.png! tongue.gif

But you are right, for the average OC'er a Classy is more suitable! This is only for those unsettling minds that NEED challenges and like their RIGS to look like science fiction labs! But the feeling that you get after this is done is overwhelming! thumb.gif

I read that part, but it just confused me when said it would over-volt GPU to 1.23v, I assumed that was tops! biggrin.gif

So could you put 1.3-1.35v through it safely? I use the term safely loosely tongue.gif


I already have glasses, just not had my prescription checked recently tongue.gif

Guys getting my gtx 780ti evga SC ref card and I'm so excited. Now I want to know which are the best drivers or nvidia is not like AMD took me 2 months for stable drivers with my 7970 also for games like bf4 crisis 3 total rome 2 AC black flag which is the best driver. And any tips you guys recommend for oc I won't push it like crazy but do want some oc on the bad boy. Thanks!

congrats on your new 780TI thumb.gif
Latest NVidia is good for Gaming. I also just got a second EVGA GTX 780 TI SC ref cooler. Didn't pay for ACX like my first card as the stock cooler went out the window within 48H.
without changing the bios I SC could do +115 Core + 100 Memory. but if you simply crank the power target to 106% you'll already get good performances.

With Skynet bios you can really have fun and push the card and increase the voltage, but always run stock for a month in case there's some defects and the card burns while on a mod bios.


it slices bread also. 4 Slot bridge.

That is just a reference value, with a variable resistor you can control the voltage intake, just need to measure it when you do, fire up GPUz render test to set the card into 3D mode and increase/decrease resistance while measuring the voltage with a Multi Meter!
The DCUII VRM section is sturdy but i advise you to go water, heat is OC public enemy "numero uno"! tongue.gif

Go for the latest WHQL, but be advised that 334 branch drivers are a hit or a miss! Until 335 drivers, in my system all 334 crashed everything! Some users still report quirks and crashes with 335 but not like 334 ones!
Read my OC guide: OCCAMRAZOR ADVANCED GK110 OC GUIDE
Note that any reference to voltmods, LLC hack and Zawarudo's tool are NOT for the 780Ti, Its Titan/780 only!
If Afterburner doesnt work for you use PrecisionX!
Any doubt PM me or leave a post here, if not me you have dozens of good people here that can help you! thumb.gif
