looks bad against

300 mhz(26%) OC on 1150 mhz boost clock on 980Ti

Yeah I find it funny.
This is also the first iteration of 14nm/16nm from AMD/Nvidia. So they are bound to get better at it.

its the new boost, to get the max out of it.
we will see how premium cards will overclock.

maybe in a near future gpus will surpass the cpu performance in everyday computing\complex operations on a single stream of data.
they are already multiple times faster in parallelism

To make sure it won't overclock too much and get close to the stock performance of a possible GTX 1080Ti.

On the green team, you have to go back to the 8800GTX days to find something comparable to the 980ti. The GTX 4 and 5 series in particular ran hot and didn't see much extra on the top end.
The 5870 was definitely a good overclocker. 850 -> 1200+

lol


5870 850mhz @900 - MAX 950mhz = 6/12% overclock



I had 3

I am curious, how long can the GPU last under 1.3V

It's a good 25% faster than the 980ti and it is obvious that a TI addition with more cores and faster memory will come out eventually. I would say enthusiasts are doing pretty good so far thumb.gif

HD 2900 Pro, 600 -> 850+. ~40% OC. Had two that did this, stock cooling.

GTX 470, 612 -> 800+ ~30% OC. Had three that could hit 800 at least, some were BIOS modded 465's. One of the 465 -> 470 cards could do 900 (50% OC). Stock cooling.

Top end cards do not have near as much OC headroom as the top-1 card on average.

Voltage scaling and “1.25V limit”

There were some rumors spreading wildly these days regarding “1.25V limitation” or whatever on modified GTX 1080 cards, which requires here few words to explain.

Hardware itself is well capable of getting to that and above voltage output for GPU core, but GP104 chip itself now more sensitive to voltage, than even previous Maxwell generation. Part of it due to thinner physical process, other part due to challenges removing heat from all those tightly packed 7.2B transistors quick enough from 21% less surface area. Those overclockers who did 2200+ MHz on GTX 980 Ti’s are well aware of all things required to achieve those high clocks. Same principle applies to Pascal generation. So if you can manage to keep GPU cooled well and have good voltage delivery to it, you indeed can push higher voltages. Cards cooled by liquid nitrogen during this guide testwork were able to run 1.35-1.4V, reaching speeds over 2500 MHz.

Fact that GTX 1080’s capable of reaching 2.1GHz on aircooling without any modifications confuse lot of people, making them to think that these chips can overclock well past 3GHz on liquid nitrogen cooling. But it’s still silicon, with similar architecture, so reality is bit sour. Yes, it allow to get good performance without extreme cooling, but hides the fact that LN2-cooled 980Ti is still much faster than overclocked GTX 1080 due to more shader cores and better CPC performance.

This also brings and answer to the question if overvolting can help OC on aircooling or watercooling. It does not help, due to thermal, which get only worse. Higher temperature render stability and performance decrease. GPU literally overheats and cannot run high frequency anymore, even though temperature is below specified maximum temperature +94°C. Think of it as temperature to frequency dependency, all the way down from +94°C to -196°C, with slope around 100MHz every 50°C. So just like in 980/980Ti/TitanX case, over-voltage on aircooling/watercooling is not recommended, as it gains no performance improvement.

Don’t get this message wrong, as GTX 1080/1070 are still great cards for daily gaming/content creation and VR experience. They are fast, not power hungry, moderately cool. The only catch is that overclocking them is not as fun and rewarding as it was on previous generations, even considering all tricks involved to get Maxwell clock high.

so wait they lowered the boost clock to make the OC headroom more pleasant?

The source have been found:

TL:DR:
HOF GTX 1080 Air cooled: Have vbios that allow 1.3V which means it can overclock up to 2.2GHz
GTX 1080 running at 2,5GHz is from a HOF card cooled with LN2.
Quote:
Hall of Fame GTX 1080 series uses the iconic white PCB and fan appearance, 12-layer PCB, 15-phase power supply circuit and dual 8-pin auxiliary power supply interface, the new three-fan TriMax radiator (10% performance increase), as well as FlexHold special graphics support rods, special breathing light, pre-core frequency to ultra 1771-1911MHz.

In aid of liquid nitrogen, Hong Kong veteran Mad Tse overclocking this card will eventually exceed a staggering 2502MHz! At the same time enhance the memory frequency from 10GHz to 11GHz.

After overclocking, the card in 3DMark Fire Strike Extreme Lane scored 12735 points, 9000 points than the standard frequencies around improved more than 40%!

Allegedly, GTX 1080 public version of the card lock BIOS and voltage GALAXY Hall of Fame edition opens this limitation, overclocking voltage is applied to the 1.3V.

More surprising is that, GTX 1080 not only extreme environment in liquid nitrogen overclocking ferocious, some play under the same conditions of air-cooled, can reach up to 2.2GHz.
