The 780 has changed. I didn't see this really talked about in any reviews that I read but there are numerous changes going on behind the scenes, at least with my card.

First off, I want to add that I have downloaded the lastest of GPU-Z, nv drivers and EVGA precision.

My card is showing an Asic score of 87.6%

Out of 3 different reference 780's I've had in my rig and 2 Titans this is the highest I've seen.

GPU-Z is saying GK110 Revision A1, Should it say B1?
and Precision is allowing for up to +75 mv



My voltage seems to bounce all around during game play. Anywhere from 1.1 to 1.2

Also even with a 106% power target and 95c setting I get throttling due to exceeding the power target, and this is on stock volts. I haven't even tried higher voltage on this card. In fact I've let to even touch the overclocking sliders.

Card boost up 10 1045 on it's own but will drop as low a 970something.


Maybe precision is having problems reporting correctly?


My fan is also noticeably louder than any of the other Titan based coolers I've had


*edit*
for those of you who care about silly things, the vanilla evga back plate bolts up just fine. Just swapped one off of my 780's

The whole new revision thing is not necessarily going to be 780ti. I have a new revision GK110 on one of my Classifieds and it overclocks worse than my original in the other card. You can check in your BIOS to see if you have the newer revision there will be a code B in the BIOS string.

Raise the voltage and overclock it, then run Firestrike Extreme and post your GPU score. I want to compare :cool:

ok, getting there. Card has only been in my rig for about 35 mins.


Running +200 MHz so far and climbing. Boosting anywhere from 1206-1220.

5565 with Generic VGA(1x) and Intel Core i7-2700K Processor



Graphics Score5858

Physics Score11730

Combined Score2574


That's running +200 which equates to 1200-1230mhz. the clock speeds really bounce around a lot.

The max is about +215 on stock voltage

Is that +200 for the 1200mhz on stock voltage ? Meaning you haven't used EVGA Precision to raise up to the possible 1.21V ? If so, that is an impressive overclock. Raise the volts.

stock volts, adding volts does nothing because my voltage is all over the place and bouncing off the power target limit even at lower clock speeds. 106% power target limit on this card makes no sense. The card throttles clocks constantly



kepler bios tweaker won't let me touch the power controls.

EK or Aquacomputer waterblock, Skyn3t Ti Bios, Zawarudo Afterburner mod, PT 600W, 1.5ghz engaged, 1950 mem, 2880 Cuda corez, ludicrous speed!

Congrats on the new beastie.:p
What kind of temps are you getting at those clocks while gaming?

I get my evga superclocked 780 Ti Monday. wee! It has the 1046 MHz boost.

I'll just live vicariously through you. How's it compare to one of your max oc 780's? 5 % better? 10?

I have no problem with that, I live vicariously through my line cooks too... if you know what I mean.


I would be lying if I said the difference was game changing but there is a noticeable difference in some titles.

I can't stress enough how different this card behaves than any of my other GK110 cards.

seriously, without touching any sliders in precision the card is constantly fluctuating between these:

1020 Mhz - 1.112v
1032 Mhz - 1.150v
1046 Mhz - 1.187v

This card seems to have a very high out of box boost potential


with +200 I see exactly the same scenario's including voltage numbers just exactly 200 MHz higher.

Just flashed to the skyn3t bios. It stops the throttling but also default my voltage to 1.012v which means I have to add voltage to get back to my stable +200.

I wish kepler bios tweaker would allow me to make my own power target.

I might just go back to the stock bios since using the skyn3t bios is only getting me to 1250mhz stable with max available voltage 1.21.

Stock bios is netting me 1232 on stock voltage with some throttling here and there.

Ultimately my benchies don't change by any real amount using the sky bios so I think I'll flash back shortly

Mines coming sometime next week. Will be interesting to see how much the overclocking varies between retail models.

I wonder if this voltage fluctuation is related to the new "power balancing" feature.

It was talked about here a bit:
http://www.overclockersclub.com/reviews/nvidia_gtx780ti/
On top of the PCB we have the power connection points at the back end of the card. A single 6-pin and single 8-pin PCIe power connection coupled with the 75W from the 16x PCIe slot provide up to 300W of power — 50W above the GTX 780 Ti's TDP of 250W so there is some capacity for overvolting and overclocking. With this card NVIDIA introduces a new power management strategy called Power Balancing to ensure no single supply source is overloaded. By load balancing the power source the expectation is a higher maximum overclock — something realized in my testing. A pair of SLI bridge connections are at the front end of the PCB allowing support for up to four cards if your motherboard supports it, although a three-card SLI solution should cover everything currently out on the market. The recommended power supply for use with a GTX 780 Ti is 600 watts based on the 250W TDP.

1250 on 1.21V is likely your wall then. That is a pretty decent overclock for a reference card. If you look in that OCN thread there is a mod to get 1.25V if you want to :cool:

I was thinking of selling my 680s for 250 each and picking up a 780ti. Just to be back in a single card setup.

But for another 200$ it'll be worse performance than my 1200mhz sli 680s. 780 just can't clock high enough. Gotta be smart not to waste my money lol
