whats holding back my overclock?

Ive been trying different things and seeing how hard i can push my 780 classy, i get up to like 1350MHz before i start to see some artifacts and i pushed it to 1410 once but it only got a few frames of the benchmark in before it crashed, my temps haven't gone over 80° though im not sure whats holding the oc back, i thought the temperature would be the biggest factor but i guess not. if its not the temps holding my overclock back then whats the point of water cooling? I am running a 24/7 overclock of around 1260 MHz with no problems, why cant i push it harder and would water cooling down the line even benefit me?

 

 

here are my specs

 

i7-4770k

corsair dominator platinum 16GB 1866MHz

H100 cooler

MSI Z87 Mpower

GTX 780 Classified

pc Power & cooling silencer mkIII 1200 W

you got a below average cpu there nothing is wrong its just your cpu each cpu will get different results its obvious yours is one of the bad overclockers.

edit: wait its confusing he talks about a gpu then the cpu OC genie II?!?

Silicon lottery

on the classy? I thought those chips are cherry picked to overclock well....

sorry, the main question was about the GPU

Quite the opposite, there's nothing special about a 4770k, it's basically a 4670k with hyperthreading, nothing special, one CPU can overclock to 4.8GHz stable at 1.27v, and another can barely make it to 4.2GHz at 1.3v

 

Even worse for a GPU, a gaming GPU is usually bottom of the bin, the Quaddro cards are cherry picked extremely high binned GPU's.

I don't have much experience with NVidia, but 1350mhz is not a good overclock? I'm pretty sure it's an aggressive overclock

It is it's a pretty nice OC I'm a little confused.

yea, i mean its good....but if my temps arent even that high would water cooling even help me push it any harder?

Maybe even with a cherry picked "classy" GPU, you're still hitting the silicon lottery limit. So I guess in that case, watercooling won't give you more performance, but it will lower your temps and noise levels (probably)

Well your using a GK110 die which since it's so large speeds can't be as high as say something like GK104 chip (gtxi 770). Normal agressive overclocks for 780's are 1000-1150mhz so you have a pretty huge overclock(863mhz stock)

i dont think im making myself clear... i know im getting a good overclock. but whats holding it back from being better if its not the temps? is it just a limitation of the silicon or voltage locks? maybe im looking too far into this...

watercooling helped me a whole lot. My 100% load temp in kombustor used to be my idle temp on air.

It could be either one, but I don't think you can do anything about it, either way, right? (Watercooling won't cure voltage lock or silicon lottery)

everything has it's limit. Eventually the chip just can't go any further even with more voltage. And then temps also are a restraint.

one of these days, you will hit the limit of the silicon itself, i think that's what a lot of ppl been trying to say.

 

I wouldn't be surprised if you've hit the limit or getting close to it

what i think happens is that nvidia says that due to gpu boost 2.0 temperature will be onliest thing that will hold your card back; or at least that was the feeling that i had; but for what you experienced seems more like merchandising than anything else, so be happy with the awesome cooler you have and the pretty nice oc u also have.

 

From my point of view is the lack of voltage what is holding your card back; just as if it was a cpu, needs more juice for that certain frequency

You are at the limits of the die. like I said earlier the GK110 die is pretty big and the bigger it is the less stable it is at higher clocks. Your looking at about a 500mhz overclock which is about as high as it goes on air for a gpu.

Someone got a Classy to 1400+ Mhz... ON AIR, and it was stable! :O

What are people talking about in earlier posts? What does a 4770K have to do with a 780 overclock?

What's holding it back is that the GPU can not handle running at that frequency on the voltage its on. as your voltage is locked there is bugger all you can do about it...

 

You just have found the limit of your card.

 

Move on and enjoy your games..if your not happy go SLI.

The limits of the GPU its self. It just won't go any further. It's not always temperature. Sometimes it can only go so far.

 

You can increase the voltage but that will also only go so high. These chips don't go to 2ghz just because your at 70c
