Very interesting, but then why does the water cooled seahawk offer only 200w? And what overclocking tools did they use to get 291w?

I'm trying to wrap my head around why anyone would care about power consumption when discussing overclocking.

The very nature of overclocking causes power usage to increase exponentially as an after effect. And anyone overclocking anything understands this.

With some video cards and some overclocks they can end up using a little more than double original power after the OC.

It's just part of the game.

Because the power limit in GPU boost on Nvidia cards is often the limiting factor for how much you can overclock them.

If a measured figure like this is accurate, then it means there is a way to bypass the voltage and power limitations.

Nvidia GP102 Titan coming soon

Despite AMD is telling the world that the $649.99 Geforce 1080 is too expensive, Nvidia partners insist they can sell as many cards as Nvidia can supply. Now there is a faster version coming, based on GP102 even bigger graphics chip. We don’t have many details about GP102 other than it is fast enough for Nvidia to call it Titan. There is a chance that there will be a Geforce GTX 1080 Ti branding but our sources are telling us that Titan is more likely.

Boutique vendors including Origin PC, Maingear, Falcon Northwest, Velocity micro and a few others tell us they cannot get enough of the high end cards, as this is what their customers want. Now with the fade out of the original Titan and the fact that Geforce GTX 1080 is faster than the original Titan card, there is a space for a new card.

We expect that the card will sell for $999 and people are willing to pay for it. Our sources are confident that this is a really big chip, much bigger than the GP104 with its 314 square mm and yet smaller than gigantic GP100 used for Pascal supercomputer cards. This is a bigger Pascal based chip, manufactured using TSMC's 16nm FinFET process with more Cuda cores enabled compared to the GP104 and Geforce GTX 1080.

This is not a HBM 2.0 card, as far as we know, the card will use GDDR5X memory. If it does even a bit better than the Geforce 1080, which was the most successful high end selling product in more than a decade, then Nvidia will be laughing all the way to the bank.

Looking at gp102 from tech-spec perspective there's no new info in that article which wasn't already hinted at.

The card has its clock default frequencies set at 1898 MHz (boost) / 1759 MHz (base) with a reference clocked 8192 MB GDDR5X / 10108 MHz effective data-rate on the memory. With the help of their tweaking software by pressing an OC mode you can instantly get another boost in perf as the clocks will change to a GPU Boost Clock : 1936 MHz , GPU Base Clock : 1784 MHz, that however requires the software to be run in the background at all times.

I'm puzzled. Why those two modes with a difference of 38 MHz (OC) and 25 MHz (base)? What is even the point in that miniscule difference? Why did Asus bother to add it?

I think it's their overclocking software, it currently offers 3 different overclocking profiles. One of which is stock speeds.

Guru3d mentioned that all 1080's are basically limited by Nvidia at a hardware or some other deep level preventing high overclocks. That ROG Strix only goes to 2050mhz. Same as the 600 series. Mid range, gimped overclocking. Must wait for real cards to come out if you want good OC's.
This whole thing still pisses me off. These are mid range cards. They don't even OC very well. They are not much faster than existing flagship cards. They are only exciting at a mid range price point. That's the whole reason for them to exist. They are exciting at a mid range price point, but disappointing and lack luster at flag ship pricing because they are very obviously not a flagship caliber of product.

What makes you think that next year's generation will have better OC's? It is in NV's interest to keep the same steady performance progression and that includes OC capabilities.

It doesnt really matter how well GP102 will overclock with 50% more CUDA cores since it will be TDP limited with a reference cooler. Even with a 1500MHz boost clock it will have a TDP of 230W. With the same boost clock as GP104 it would be a 270W chip.

So outside of triple fan, triple 8 pin cards nobody is going to be complaining about lack of clockspeed since both cooling and power delivery are going to be major issues with the big die.

Nvidia gimps the OCability of the mid range cards so that they won't step on the toes of their over priced high end chips. The only down side is that the new mid range cards don't look very good compared to last gen's OC'd high end cards, but when you are trying to rip off your entire customer base twice each generation, something has to give a little and the 1070/1080's poor OCability is what had to give, same as with the 600/700 series.

I was told by a couple different folks I know from other forums that usually "dig deep" in to the bios of different nvidia cards at the hex level. And I was told that nvidia permanently limits the voltage of pretty much the entire 700 line up of cards to 1.212v And nothing can change that. Not software, not bios mods.

However there were a few notable examples of certain board partners that released versions that ignored (and violated) nvidia's mandate and allowed the voltage to be clocked much higher. One was the EVGA 780 Ti Classified, and EVGA 780 Ti K|NGP|N editions. And (I think) Galaxy HOF / Hall Of Fame editions. There may be a few more.. but typically you could count these "unlocked" cards on both hands.

I think I heard EVGA got in "hot water" with nvidia over all of this and isn't allowed to do this sort of thing any more. But I can't find proof of this anywhere.

Locking the voltage like that locks the overclock. And I remember hearing that the voltage changes with the 900 series were similarly locked and even if we could push voltage, it didn't go very far, like +0.050 mv for example.

So I'm not terribly surprised seeing nvidia do this with their mid-tier line of cards this time around.

Part of it is planned obsolescence. It forces people to buy a higher tier of card if they want the higher performance.. instead of buying a lower tier card and overclocking it to the sky and getting the same performance as the higher cards for less money.

I do believe those days for nvidia are long over now and this will be the "new norm".

I may be wrong on all of these assumptions as they're just rumors I hear between friends but it is appearing to be that the 1080's are all voltage capped in some form that isn't changeable without "hard mods" (soldering things to the cards), at least so far. Almost all GTX 1080's overclock to the 2ghz - 2.1 ghz range even founders edition and the only difference in aftermarket ones is better cooling. Even additional power connectors don't let us clock further past a certain point.

Sure, they gimp them, but it sounded like you didn't think they would equally gimp their "high end" cards either. Probably just me misunderstanding your statement.

I predict they will gimp every generation forward to make performance end up exactly where they want it to be. I don't really make a difference between what you guys call "mid range" and "high end" any more. We are getting a new top card every year, and it is perfectly tuned to improve by 20-30% without OC'ing "too much". That's it. Doesn't really matter what the properties or the size of the chip is anymore.

Planned obsolescence means manufacturers design products to fail within a certain lifespan so as to incentivise new purchases.

Gimping overclocking potential isn't that.

No, you are right. I was a fool to give Nvidia the benefit of the doubt in assuming their high end cards had better OC potential. At least that's what it seemed like to me. The 980ti OC'd pretty well and I seem to remember the 780ti doing OK as well. The mid rangers have been real crappers for OCing though.
I guess it makes sense to limit them all. If that 980ti OC'd any better, that 1080 would really look silly. They just can't have that when they want you to buy a new mid ranger for $700.
You see, the only reason this is an issue is because the performance from one generation to the next is almost on top of eachother. The delta is laughably small. That's because you buy a high end, then they want you to buy a mid ranger tinker toy to replace it. The delta is small. It used to be you buy a high end and then buy another high end. The delta is wide. There is no reason to jack around with OC potential if they are playing honest like they used to.

Received my Zotac GTX 1080 FE this afternoon and spent time putting on the EK GTX 1080 waterblock. All is running well. Fast card even at stock. I'll be working on overclocking over the week end.

And some soldering skills :\

Ah, I was referring to the rather easier idea of simply upgrading to big cards every two years

Pushing the limits of overclocks I have no idea about, but I'd be surprised if they stopped the AIB's doing it entirely. Those fancy things they do do attract quite a big premium.

Max OCed Strix almost matches stock Geforce GTX 1080.


Geforce GTX 1060 is coming...

Asustek enhances gaming notebook marketing

Asustek Computer, viewing that gaming notebooks have become a main source of consolidated operating profit, has recently strengthened marketing strategies for the second half through adopting Nvidia Pascal-architecture GPUs including GeForce GTX 1080/1070/1060 to hike hardware specifications as well as setting retail prices comparable to those quoted by Micro-Star International (MSI) in the US and Europe and those set by Haier in the China market, according to industry sources.
