I sure hope that EVGA takes this into consideration from the very beginning, and not leave the power limits set so horribly low in the stock bios versions, like they did on the ACX 2.0 970s.
Unlike NVIDIA, I sure hope that EVGA has learned from the Maxwell debacle.

True....but should you REALLY have to do that to just get the performance that they're "advertised" to have? Seems like poor planning to me....

Or to get the performance that YOU are wanting to have...? If the "throttling" you are talking about is meeting Nvidia's requirements to make the 1080 function and function correctly but it does not allow overclocking of what you are wanting, it's not their problem.

Nope, you shouldn't have to. I always run a modded vbios though to make sure I'm getting all the performance I purchased. Even when I'm running the card at stock clocks I have a modded vbios loaded to prevent any throttling. kwkrnu72
Uh, no.... This looks like a lot of power limit throttling at not even the stock boost clock. lol

Furmark is blacklisted inside the nvidia driver and will cause the card to throttle.

Throw another 6 pin on there and add (or even populate) another phase and most cards will easily hit 2.1Ghz. Can't wait to see what the FTW edition will look like. Probably hit 2.5Ghz.

This...and give them appropriate power limits set in the stock bios files. The 970 ACX 2.0 cards were horrible.

The stock power limit on the Founder's Ed. cards is 222W which is just shy of the 225W allowed for the power connectors the card has. 8-pin = 150W PCIe = 75W So with a BIOS mod you might get another ~15W on the standard card with a single 8pin. Still that can be pushing it depending on your power supply.

You can pull 175 from an 8 pin and 80 from the lane.
That said....I really doubt that anyone that's serious about overclocking their card, is going to buy the founder's edition.

But what purpose do you have to overclocking? is it only to see how far you can go so you can put it on paper? Or is it so you can go from 120FPS to 130FPS and say that you did it?

Sometimes, yes. Benchmark performance, game performance increases....whatever floats my boat. That's why they make cards like the SC / SSC / FTW / CLASSY / KPE....because people want better performance than stock clocks.
If you don't overclock, and are happy to plug something in and play....then this obviously isn't a large concern of yours. lol

I didn't mean to sound like a disturbing troll. I'm just trying to get understand because they have really hyped the smoke out of these cards, right? And with all that horsepower, it seems like we don't even need to overclock, because of all that hype, right?

In the past I've been one to stay with stock cards, or factory overclocked, and not twiddle with them myself. But, I see how easy it is to use the OC utilities like the one EVGA furnishes, and I'll likely give it a try. I've also not used water cooled, but the hybrid series with a no-mess small cooler as part of the card package seems simple enough for me to consider it.

Im going to laugh if we see a Frankenstein project like we did a while back with the entire vreg section of a GPU got lobbed off and plugged into the newer GPU to supply it power for over clocking.

All the demo's I've seen were able to overclock above 2ghz with a stock FE card and the EVGA Precision X free sw utility. At the product announcement the card went to 2.2 ghz (which is the best I've seen).

The presentation card was only running a benchmark, however. Not sure how stable it would be in gaming. I have seen a few testers that claimed they were unable to take it over 1900Mhz as they ran into power throttling. Depends on the chip you are dealt.

There are ways around power throttling....I'm just hoping that EVGA or some of the other partners use some common sense this go round, and not make it a requirement to bios mod for just about everyone wanting to overclock their card a little bit.

The only reason for power throttling, which makes sense to me, is they are having the GPU maintain the Frequency, and if the "power throttling" is occurring, then it is cutting back on the power, because the power which is being pushed to the card is not needed all the way, which is why the power throttling is occurring. Obviously these cards do not need as much power as Maxwell, and I think most of everyone is forgetting that. If nobody understands that... These GPUs apparently don't need all "that power".

Thats a very informative video. ty. I was going to leave a positive comment on youtube but it wanted me to create my own channel first. When did they start that? I've had a youtube account for along time, and a google account. I do not create and up load videos (so far).

You think GTX1080 custom cards with 8+8 pin and custom power target will work better? I could imagine how good will work GTX1080 mobile version in laptops. But they will show up next year. GTX1080 is perfect for laptops.

Of course it would be a low power version of Pascal. I think I've read/heard that is being planned. Probably not close to a full size card in graphics performance. Next year Intel will have its next generations of processors and on-board graphics out. They are starting at the low end with the next gen of products. I think I saw a graph showing 4x the graphics power from Intel's next chipset. Thats going to heat up the competition in the low end market a lot. thats speculative at this point.

Uh, no....that's not even close..... The power limit perf cap occurs when the GPU exceeds the specified power limit set in the bios, and the card throttles to get the card back under the prescribed power limit. By raising the power limits in the bios, you can extend the potential of the card, and thus the overclocking potential. The ACX 2.0 970s had a 170 / 187 watt power limit set in the bios, which was just WAY too low, and a good many of the cards would power limit throttle the core, before they even reached peak boost 2.0 clocks. They addressed that issue with the ACX 2.0+ 970s, by raising the power limits base to 220 watts, giving them a little more head room. Many of us that were pushing the 970s pretty hard under water, had to set power limits in the bios to 300+ watts just to keep the power limit perf cap at bay.

This looks more like thermal throttling to me. Because the graphs shows that it works for a period of time at that overclocked speed, then once it generates so much heat the GPU chokes.
The blower cooler is garbage. The water cooled overclock was perfectly stable.

The bios voltage setting -probably- tweeks the voltage regulator hardware. The regulator hardware (firmware) will also have a range of values which it can handle in a stable manner. If someone has access to parts lists for the various 980 cards it would be interesting to see if the cards with a higher overclock potential use the reference card voltage regulator or another one.
