[Chiploco] EVGA GeForce GTX 780 Classified reaches 1410 MHz on air

The overclocker also reveals that EVGA has prepared a standalone voltage tuner for the GTX 780 Classified which will enable it to reach some crazy frequencies on air.

Edit: Probably should say something too.....


Better get them if you're interested before nVidia nerfs the voltage tweaking ()

Is this allowed by NV? Thought they don't want custom software overriding their set voltages.

nVidia said that they allow overvolting as long as the AIB covers the warranty on their own.

I heartily laugh at anyone who thinks a real user can actually achieve a kingpin overclock. Great marketing spin for EVGA, they did the same thing with a 1600mhz GTX 680 So many real world users got 1600mhz on their 680s, not.

EVGA won't even confirm that over-voltage is allowed on the EV bot, which tells me it probably isn't.

 

[BallaTheFeared]

Actually Kingpin only hit around 1400 with his 680 on air, and that was with unlocked voltage control.

Pretty sure some of the better 680s such as msi lightnings hit that on air as well.

That doesn't change the fact that sample varience is and always will be king, but if it's unlocked, and you got a good chip you'd crush the Titan with water.

Jacob at EVGA was directly asked probably hundreds of times as to whether EV bot will allow over-voltage on the 780 classified @ the EVGA forum. He has directly avoided the question or at other times only provided vague hints that changed the topic. Go check for yourself. He will not answer. HE won't even answer PM's asking the same question. What does that tell you? To me this indicates that it won't be allowed. Furthermore, as far as i'm concerned, the 680 classified was a piece of junk. It didn't overclock better than reference, and we know what happened to the EV Bot functionality with the 680 classified (ie nvidia NIXED it)

We'll see what happens. But i'm taking this as a kingpin overclock that no mortal will ever achieve. I highly doubt that EV bot will be allowed when no other 780 has voltage control (not even the DC2 780 with VGA hotwire, nvidia said NO) and the fact that JacobF has outright avoided answering the question. If he's avoiding the question, that means the answer is likely no. If nvidia said NO to asus hotwire, NO to MSI, then they'll suddenly reverse course and allow it with EVGA? Yeahhh...ok.

So I think this will be a worthless overpriced card just like the 680 classified IMO. Maybe i'm wrong and I hope I am. But I think the EVGA SC ACX, Asus DC2, or gigabyte windforce cards are far preferable purchases unless the EV bot allows over-voltage...

Forget the Classified.... I can hear thunder rolling in..

I can just hear it now.

"OMFG MY I PUT MY LIGHTNING SUPERCARD TO 1.8 VOLTS AND NOW IT DOESN'T BOOT. NVIDIA SUXORS. LIARS TOLD ME I CAN OVERVOLT BUT IT DOESN'T EVEN WORK."

 

[thilanliyan]

^Afterburner has limits to prevent that doesn't it?

It usually does after the first batch of RMAs from killed cards

That's what happened in the past for lightnings.

LOL...sure they do :whiste:

 

[tviceman]

1400 mhz is ultra impressive, I wonder what the real-world performance scaling and temps are like with that kind of speed though.

 

[hawtdawg]

200% power limit means 500w TDP. lolnope.

 

[BallaTheFeared]

Well at least you wouldn't have to worry about being TDP constrained like current Kepler users are :|

 

[hawtdawg]

With the bios modded to 300w, the 780 isn't constrained by TDP. it just becomes a voltage limitation.

 

[wand3r3r]

If that's not an extreme one off cherry picked card it'd be a great card. I would like to see some benches and comparisons to a 680 @1400. I'd bet it scales noticably better then the 680/770.

I wonder what the voltage thing is, if its only tdp that's weak but if you can increase the core it'd be great but I doubt nv let them.

 

[BallaTheFeared]

Seems this offers the whole picture, TDP limit made null and voltage control (basically the reasons I avoided NVidia this gen are now gone) - looks like 3 different voltages, probably core/ram/ppl would be my guess but then again it could be pure bs? Should have review samples out soon so we'll know better then.

No question this chip is pretty cherry, but that's to be expected. The real question I think is if it's truly an unlocked chip like Fermi was, or if it's just blowing smoke up our rears.

 

[hawtdawg]

Id imagine that quite a few 780's could hit that speed if you gave them that much juice. It might even finish a Valley run or 2 before it started smoking.

I'd probably do at least 1.3v on water with it, 1.35v on air though, unless I'm missing something seems like a bit of a stretch. I don't think a lot of Tahiti users run 1.3v on air 24/7, just for benchmarks.

Surely will be interesting to see how that plays out and what the limit is on shipping products if it's 1.35v or 1.2~v that current Kepler is forced to cap at.

If they warranty 1.35v though, I wouldn't personally have a problem taking it there for benchmarks.

I really can't imagine that they would. We'll probably see something like 1.275v max with a 350w TDP or something. Though that should still let the 780 stretch its legs some.

 

[bunnyfubbles]

yeah, there's just no way that kind of clockrate and voltage is going to be viable on air for actual gaming. This is just one of those instances of "I got it to POST!" but its nowhere near actually usable. BFD.

~1100-1150 is easily the reasonable limit for air (if you can put up with screaming fans), and current 780s pretty much can do that already

This will certainly be interesting for water as we'd probably see some regular 1300MHz clockrates, but any talk of "on air" is misleading without also saying its pretty much a suicide run.

 

[BallaTheFeared]

It's no less than what we see from AMD users and their 7 series cards. People pumping 1.3 volts into their cards maxing out the slider and artifacting their way through benchmarks for higher scores.

3DMark isn't exactly a cake walk to pass, so gaming stability at that voltage assuming EVGAs cooler can keep up shouldn't require too much loss in the way of clock rates. Nobody can really argue if Kepler can handle 1.35v on air, because nobody has actually ran it

I agree though, this card would be for water coolers imo. The people who could take full advantage of the increased voltage - I'd imagine on water 1400 chip willing might actually be a possibility for gaming.

Nah, I have a reference MSI 780, and with the TDP at 300w and 1.212v@1202, I can play BF3 for hours with vsync off and never leave the 70's. This is with the fan never breaking 65% either, which is practically silent compared to how loud a typical AMD cooler would be on a card pushed that hard. With a non-reference cooler like the ACX, there would be plenty of thermal headroom left.

 

[tweakboy]

You have to be seeing artifacts I would thinks.
