""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. So just like in 980/980Ti/TitanX case, over-voltage is not recommended, as it gains no performance improvement."

SO any card will do... No matter what.. Oh well now i dont feel so bad getting a founders because evga wasnt faster enough to release their $610 bucks card...

If zombie cards cant do it anyway lol

2500 on ln2 and 1.35v wink.gif


oh I did not see above post but yeah tin has stated clocks that were reached already

No.

If Nvidia really wanted to get all the juice they could out of these cards, they wouldn't be coming with a 180 watt power rating.

They set the power rating and then tune the ship for max performance while meeting that rating.

so no one learned anything from maxwell?

and no one thought since pascal is "refined" maxwell, it would show the same behavior?

and also since it was a node shrink, it may exacerbate the behavior?

pretty sure i said it before; it caught my attention when voltage ripple was mentioned in the presentation. i am wondering if that doesn't hold the key since more voltage=more power which in turn increases voltage ripple and then things start to fall apart.

Servers are still up and running BF BC2? I have not checked stats on it...really enjoyed that game.

Yeah buddy! I play it quite often smile.gif Overwatch has taken over for a bit, but BC2 is always there with a few hundred people to play with at any given time.

It's funny because even the other game (which it's been a bit of time) I play is Heroes of Stalingrad which has had only hundreds of players for the past few years still has me playing on a favorite server or so. Just have to find the right server, at least for me.

Might have to reinstall to check it out smile.gif

Pretty good looking card compared to the aib´s, downclocks at 82c with fan profile auto,60% fan speed holds well the OC

Tested Dying light in two minutes 83c, gpu power 87% fan profile stock downclocked to 1650mhz. so far i have tested and confirmed some reviews

will do some more testing in the next few days
