Hello EVGA fans and enthusiasts,
So, I have decided to keep my 780 classy (after wondering whether to trade it for a 780 Ti) and I am now moving on to setting up this beautiful card.
I tried looking online a bit, but didn't find good, centralized (and more importantly, easy to understand) information.
I was wondering if you guys could help me out with good guides for setting up and, more importantly, to untaping the power of my graphic card. Mind you, I am quite a noob regarding GPU OCs (but I learn quite fast) so, the easier to follow and thorough the information is, the better.
Thank you very much!

Hello Bluvert and thank you so much for that link.
Well, I have come across it... but 900 pages of info make it difficult to actually have a good grasp of what to do. I am sure there is super good info in there but it is either geared towards people that are already completely familiar with the graphic card (and the OC process) or it is lost in a sea of answers. Thus me asking for a guide... like a Dumb's guide to the Classy! :)

Honestly, there isn't going to be a guide like that. It's just playing with your card in precision or afterburner and finding how far you can push it given your specific system. The link I included has a modified bios and voltage controller you can use to push the card further, but it sounds like you just need some time to get familiar with one of those two software tools.

Well... I will try looking around the thread you suggested, even though I am sure it will be like finding a needle in a haystack! :) On top of all, even if I asked for help there, people only seem to care about the GTX 780 Ti classy. I am being discriminated! :D
Anyway... I am just looking for some basic info where to start. For example, I just found out the usefulness of the two bios! :) Also, what is the boost? I didn't quite get that! I know... I am a disgrace! :) Is the boost automatically enabled?
Regarding bios... which should I use? There are several modified Bios... Is there any recommended Bios to flash to unlock the graphic card restrictions?
And again, if anyone could share a step by step on how to overclock (something simple), that would really be helpful.
Sorry for these very naive (and ignorant) requests for help.
Cheers

Boost is basically it "overclocking" itself depending on temperatures. some people dislike it. some people like it. Don't pay much attention to it. On that overclockers topic pick sky's REV3 bios. make sure its for the 780 classified. not the 780 Ti classified. And then you need the classified tool which allows you to controll voltages. Latest version Basically use precision X. start gently overclocking. when the card starts to artifact(glitch out) add more voltage to it to stabilize it. i basically just started at 1,3V and overclocked till I reached the limit and then steadily increased voltage. It takes a while. And then you basically stop when your cooling cant handle it or if when the chip just reaches its limit which depends on the lottery. My Ti classified can't handle more than 1358mhz(+200) on core at 1,39V + memory at 3966(+690)mhz Card wants to keep on going but my cooling just can't take it since I am using air and its reaching 90 degrees and going higher any harder makes the card throttle

Hey Dark! Thanks for that...
I will start gathering all those tools and bios.
In the meantime, I was wondering how exactly does one do the overclock on the precision X? Do I start by increasing the core (by 13Hz increments)? When do I stop increasing the GPU core? And what do I do with the memory clocks? When do I start pushing it up? How does one decide on a voltage to start with? Should I just start with the standard voltage? Also, for the voltage do I change it on the classified tool or in precision X (although I think this can't really be changed there)?
Thank you so much.

Milcs,
Follow what Dark said to do. Work within the limits of what Precision will allow you to do and you should be safe. When you are comfortable with Precision, your card and cooling, ONLY THEN should you flash it and unlock the voltage. Without flashing or unlocking, you are not putting the card at much risk if you monitor the temps closely. Once you remove the voltage limit, things can happen pretty quickly and expensive parts can release their magic smoke. Once that happens, you have to buy new magic smoke, and that is only available within new components.
Have fun and be safe.

OK! I will first try upping the core and mem with precision X. I just have no clue how to increase the GPU speed and the mem. And how do these relate to one another and... how to they influence the efficiency of the graphic card.

Thank you so much.
Basically start out with everything stock. open precision X. power target to maximum. temperature to maximum set the overvoltage to maximum on PX(its to the left click the voltage button). Then what I do to make it easier is just set the core to +100. Run a benchmark or a game and see how it reacts. If its a instant crash then you drop it by say -20(+80) and test again till you find that magic spot where it run stable. same thing with the memory but memory overclocks way higher in numbers so I just went instant up to +500 and see what happens. when you found the absolute limit on stock. Then you can start going beyond stock. I don't know if the classified tool works with the stock bios? somebody will probably answer me in a quote here. Basically open up classified tool. you got NVVDD: GPU core voltage. this needs to go up to allow more power to go to the core so it can overclock higher(maximum on the newest one is 1,65V but don't touch that. air cant handle that.) FBDD: This apparently is the voltage going to your memory(I think). increasing this helps with memory overclocking judging from what I saw on Overclockers PEXVDD: is apparently the voltage of the PCI-E slot. nobody knows if this helps with overclocking. PWM freq: I think this is some complicated stuff about the frequency of the power going into the transistors or something. increasing it might make a overclock more stable apparently. Also don't be afraid to make a account on overclockers and asking them for help they are willing to help. milcs

Core and mem are GPU speed and memory. Core = speed of the GPU chip/core of the graphics cards mem is well..memory speed.

The tool does work on the stock BIOS. I have done it. Problem is, I run into the 115% power target (on LN2) BIOS before I even reach 1.2V. I guess that is good that it only takes such low voltage, but still annoying. I really need to try skyn3t BIOS, but haven't tried it yet.

I never understood the meaning of the power target. what does it actually mean?

Power target is a variable that can be used to overclock with GPU boost. For example, running at stock 100% power target means that the card will run and draw it's rated wattage say of 250W at full load. By increasing the power target to 115%, means that now it will use and draw and additional 15% over the 250W which is approximately 288W under full load. More power should equate to ability to get higher, stable clock speeds. Of course, more power brings higher temperatures as well. It's all a fine balancing act when overclocking. Hope that helps and makes sense.

Hello again and thank you all for input and guidance! :)
So, should I be using the bios that allows for the 115% power target from the start? Or should I start with the 110%?
Which programs should I use to test the card? I have been reading about Heaven and Fire Extreme (maybe I got this wrong)... Are these the programs to use? What about the ASIC score I keep reading about, how do I check this and why does it matter? Finally, what is the OC Scan program from EVGA and why are people using it?
Again, sorry for my total ignorance! And thank you a million...

Just go for the LN2 bios switch instantly and put it on 115%. I personally bought 3Dmark (firestrike) for benching purposes. I dislike using heaven because for some reason that program makes my overclock just die. no matter how little. every single other program works. firestrike, games, metro's benchmark but the moment I touch heaven(or valley) BAM crash. you can download the firestrike demo though. which just lets you run it but you can't edit it but hey its a good starting point to check stability. ASIC scores are if i remember correctly the "quality" of a chip's circuitry. if I remember right a low ASIC score makes it more fit for LN2 overclocking and a high ASIC score makes it better for AIR/water. but honestly nobody knows if it really matter that much. my asic is 69,1%. you can check this by downloading GPU-Z(techpowerup version is best imho) and then right click the top of the window and you should see a list and it should say "check ASIC" if you can't find it I will take a screenshot later. The OC scanner program is what it pretty much says. it basically puts alot of stress on your GPU. like fully loading the memory and pure stress testing. I use it abit since most of the time It is decently accurate for when the overclock is too much. It is pretty simple stuff really. I was like you. I just knew about dragging some sliders on a program but hey it took two days and now I am fiddling with voltages and stuff.

So I am now playing around with overclocking my precious 780 classy! :) Quite funny... Men and their toys!!! So, my 780 came with the Hynix (I was hoping to get the Samsung, from reading around forums... as it "seems" it is the best memory) and I get a 70.7% ASIC. I am using the LN2 Bios and set up the Power Target to 115% (and the linked temp target to 95%). I have then started by increasing the MEM clock offset to +500. This doesn't do anything... At least, no change I can actually observe. I then upped the GPU clock offset to +200 and this immediately lead to a crash. I then used the overvoltage in precisionX to increase the voltage +63mV. I am now at 1200mV (no idea whether this is what I am expecting or not!!!). I managed to get up to +176MHz to get a clock of 1319-1320MHz. Have been running exclusively OC Scanner X and so far so good. Temps hovering around 73-74ºC. What do you guys think? Another little doubts I have... On Precision X the sensors show the appropriate clocks for GPU (1320MHz), Memory (3506MHz x2) but the power never goes above 88%. I am quite confused with this. Shouldn't it be going to 115% (as defined in Precision X)? Why does this happen? Final question... Why is there a red led on the back of this beautiful card? Can this be turned off? Cheers!!! I am excited... :)

Memory overclocking does not give huge improvements on its own but combined with a core overclock it does help. Increase the voltage to +75(i think) so you are at 1,21V which is maximum "standard" voltage. I would advise you to actually run a game with it. just to be sure that it's stable. if you can get 1319mhz working on just 1,21V then I am very jealous as I could only get to 1280mhz. Either run a game or download 3Dmark(there is a free version normally) to check it in the field. OC scanner works most of the time but its not perfect in terms of power target. What are you running on OC scanner? Because for example the phsyx test only uses 40% power target while here when I run furry donut(GPU core burner) it jump to 112%. I am pretty sure you aren't using the furry donut thing since no way in hell can you run that at 75 degrees. my Ti classified instantly jumps to 95 degrees when im running that. That thing is BRUTAL and the RED led shows you what bios is running. Red = LN2. no idea what color stock is. White? green? all GPUs have LEDs on them these days. some use it for bios indication. some have them next to the power connectors to show you if the connection is right or not. It's normal.

Well... I am not entirely sure about what I am doing! :) So don't be jealous... In any case, I came back home and ran the same tests and I was getting a clock of around 1250MHz. With the exact same settings... It's really odd! Restarting the computer changes the clocks a lot... It is now running again at 1320MHz. For the voltage (through precisionX), the maximum I can go is +63mV. Is that right? I can never get to 1.21V. It is always around 1.2V. For the power target, I am running the different GPU core burner tests (Fury E or Fury Donut v1 and v2). Again, as you can see, the power hovers around 80-100%. Never reaching 115%. Really don't get it... To make it even more odd, when I came back and it was giving me a clock of 1250MHz, the power was indeed at 115%. Now that is back at 1320MHz (which happened by... magic!!!), the power is around the 80-100% marks. Does this have anything to do with the speed of the fans? I seem to have read somewhere that the speed of the fans were taken into account here... In any case, I am completely lost here! Bellow you can see the screen for my present settings.  Regarding the LEDs, I understand it is normal. I was just wondering if it is possible to turn them off! :) It doesn't go well with my blue mobo and cables! :D And the other white LEDs (the cute ones), can we control them? I can't control them with the GeForce Experience program. Is this normal? Finally... I don't seem to be able to manually set the fan speed in PrecisionX (can do it using open hardware monitor if precisionX is not running). Anyone knows the reason? Thank you all!

Weird that you cant use precision X to put it on 1,21V oh well.
you got the classified tool to do that. I wouldn't worry about the power target thing. in a way its good because it means your GPU isn't hitting the powertarget limit yet.
No you can't turn off the LEDs. I would just take them with black tape or something if they really bug you since you don't really want to cut up the LED to break it.
Fan speed. click the blue block next to auto to turn off automatic than the arrow to the right of that bar becomes moveable.
also sometimes precision X seems to mess up. mostly when my overclock was unstable it tends to do weird things like get stuck zat 580mhz or 1100mhz for no reason and the only solution being a reboot.
WHICH ISNT A BAD THING. because (I don't know about for the 780) you can turn on something called K-boost that forces your GPU to be running at the set voltage and core mhz all the time. if you are overclocking with that on and the overclock makes your drivers crash and K-boost ist on and it wouldn't lower the clocks it would just keep on using the same clock and you end up in a endless loop of drivers crashing.

Edit : ^ ninja'd! If you want to manually set the fan speed then uncheck that blue box next to "auto". Or click on fan curve and set up your own speed increments according to temps. I usually do 10% speed over specific temperature. I.e. 50% speed to 40C and on up...but that's just me.

So... it doesn't work! :|
I can't get Precision X to control the fan speed! Any clues?

The white LEDs are there to show you that the Core, MEMORY, and all other parts are receiving proper voltage. One of those shuts off and you have a problem with power, so covering them is OK, but breaking them to turn them off should void the warranty.
The red led should also be covered with a small piece of electrical tape if nothing else.

I think I spoke too early... :( In 3DMark the card doesn't take more than approximately 1250MHz (around 120-140% GPU Clock offset). Damn... I was thinking I had one of those amazing overclockable cards. After having read so many reviews saying wonders about the OC capability of the card (and with all the reviewers getting way over 1300MHz), I can't help to feel I got the short end of the stick! I mean, it still feels like it is a great card, but given all the reviews, I was hoping for a bit more on stock! Anyway... I am still confused as to why I am limited (in Precision X) to 1.2V. Can you guys confirm it should be 1.210V? Also, what is the reason the graphic card can't handle the extra speed? Given that the power never even gets close to 100% (being that the target is set at 115%) and temps are rather low (around 75ºC)? Finally... are the fans suppose to make a kind of a rattling noise at ~60-70% speed? It's like a metallic grinding noise (discreet and not very loud). EDIT: Well, besides the noise from the fans, there is a distinctive "electronic" noise. It's like someone it using morse code... Am I going crazy? Is there a little alien trying to get hold of me through my classy? :) Cheers everyone

Well, for my card, seems like max I can get in Precision X is only 1.149V. Using the overvoltage tool, I can set it to 1.1875V and not hit the 115% power target. If I increase it to 1.2V I keep hitting the power target and the card throttles down. But even at 1.1875V I have been able to get 1309MHz. I haven't tried flashing different BIOS though, but once I do I figure I am going to have a very nice overclocking card. My ASIC is really high at 89.3. Edit: in my Precision X, I am only getting option for +38mV, but I see others mention higher. Maybe I need to reinstall mine. Maybe it is still reading from before when I had a reference 780.

Hey JDookie
I will try to flash a new BIOS after I have finished checking the stock capabilities of my new card. One thing at the time... :)
I have a few more questions... I had to drop my GPU offset to +100MHz and have, presently, 1241MHz. Far from what I was hoping... :(
I tried to increase the voltage a little bit (with the classified tool), but any increase in voltage leads to an immediate decrease in the GPU clock speed (in LN2 bios). Why? I don't think that either the power or the temps are being hit, so I am a bit surprised with this.
So... should I conclude that the stock capabilities of my card, at 1.2V is 1241MHz and move on with life? :)
Why do I never get the "super card"?

You are lucky! :) Which OC settings do you have? How much are your GPU and MEM offsets? Do you have the overvoltage at +63mV?

Thanks, I am feeling pretty lucky on this card. It was even a B-stock card too. I'm not at home at the moment, but I believe I was about +160 on the core and +200 on memory. Really haven't tried taking the memory too high yet, was still working on maxing out the core clock, but am running into hitting the power target, so going to have to flash the BIOS at some point to go higher.
As I added to my post above, I only have option to +38mv, not +63. Maybe I need to reinstall Precision X as it might still be using settings from my previous reference 780.
