about asic reading...all of my cars that i had in long 10 years the best overclockers was been the cards whit higher asic reading...
what to say more...

Easiest way to explain ASIC and how it relates to you guys is that it is a measurement of the quality of the gpu and how well it can scale at a set baseline voltage.
Higher asic means it needs less voltage for XXX clock. Lower asic means it will need more voltage for XXX clock.
Prior to maxwell, ASIC HAD LESS meaning or I should say was less significant because you got a lot of voltage scaling out of Kepler. You could take a lower asic 780kpti card for example, give it lots of volts and it can hit the same clocks as a higher asic counterpart running less voltage but clocking higher. On Maxwell, we do not have this luxury of running 1.4v+ on the gpus using air/water cooling smile.gif. This means that ASIC is more relevant because "typically and in most cases" a higher ASIC card will get you more clocks with the lowest possible voltage at the end of the day considering the voltage limits on Maxwell. For the sole reason of not being able to add much voltage on air/water with maxwell, ASIC becomes more relevant this gen, not the other way around.
If you take ten pieces 80% ASIC and 10 pieces of 70% ASIC, and see how high each one clocks with min def voltage for KP980ti cards of 1.16v under 3d load, you will see the higher ASIC cards clocking the highest. There are always exceptions ofc, so not all cards will fall in line like that. Which brings us to the next part, leakage.

ASIC does not accurately reflect leakage unfortunately and THIS is the lottery part of the equation and what can cause a high asic card to "underperform" to expectations. HIGHER ASIC DOES NOT EQUAL LOWER LEAKAGE, it is the opposite. Higher ASIC has higher leakage PERIOD. Leakage and gpu scalability/headroom/ASIC VALUE scale linearly together. Lowest ASIC cards have lowest leakage, this is one reason why on Kepler you were able to increase the voltage on a low ASIC part so much and get good scaling on air water, because they had lowest leakage. Can a lower asic card clock higher than a higher asic card, YES! It is because of leakage values and all cards are different. The "lottery" is the LEAKAGE. Some high asic gpus have insane leakage numbers, This is THE SOLE reason why a high ASIC card may fall short on air/water. So much nonsense about ASIC on the net since 980KPti launched, what I explained is the real deal. Hope it helps you to understand more.

higher ASIC is lower leakage and won't need as much voltage to get the same clock speed as a chip with a lower ASIC.

prior to maxwell, ASIC had more meaning but now plays a much smaller role in OCing. your 75% ASIC card will boost slightly higher out of the box (w/default voltage) than a 72% ASIC card. but how much more you get out of it is still the silicone lottery (as usual) and what kind of temps its dealing with - lower=better.

I've finally been able to order a GTX 1080 FTW for its msrp. I'm going to install it as soon as possible before my knee surgery leaves me in crutches.

Look....I personally believe your hypothesis is correct, but it's far from sound and can't be proven until ASIC quality reads correctly from GPUz. Speculation is speculation, no matter how fervently you believe it. thumb.gif
I only believe my prediction because the numbers I've logged are indicating it. A false reading doesn't mean it's absolutely inaccurate is all I'm saying. Of course it's speculation until gpu-z 0.9.0 comes out I never said anything was concrete. The thing I'm having trouble wrapping my head around is because gpu-z is not currently supporting ASIC quality that the readings from 0.8.7 are obsolete. I'm trying to say maybe they are not considering the cards with higher readings presently are still the ones clocking higher.. I'm really not trying to start any heated arguments. It was something I decided to do in order to help people decide whether or not getting FE over say a midrange aib card. This was solely done to collect numbers the community can utilize.

No whats funny is you are spouting off about it yet you cant show any facts.


Explain to me how GPUZ detects the ASIC value of a given GPU. Go ahead let me know. Because right now the new version shows reading is not supported. Older version give me 99.5% and 100% with another version. So 2 versions 2 diff results. So update your software. Here you go if i use 0.2.3 i get a core of 5005mhz. omg i have the fastest gpu in the world. I mean GPUZ says it and it cant be wrong. It only reports the truth. And new versions dont list the ASIC so we can use that so we have to use the old versions because they did not remove it because the reading was very inaccurate


Here we go guys. Proof that a 100% ASIC or 99.5% whatever it feels like reporting because that changes because its spot on accurate lets you run a gtx 1080 at 5ghz on the core. Disregard the old version because GPUZ removed the ASIC in it because Nvidia did not want anyone to know that they can produce flawless chips and they also hide the real clocks of the card. Thats why the 1080 is so fast. Its 5ghz GPUZ told me so.





Also lower ASIC chips clock higher. Ask anyone with LN2.


Now if you dont mind i have to look up an old cpuz so i can see if i can have a -vid on my i7 so i can tell everyone it pulls 5ghz at - volts. Pretty much makes its own power its amazing. Because software is so accurate to measure things. Tomorrow at work im putting all the flukes in the trash. From now on we use software.

I don't think this was a waste of time. Good job.

Thank you for that. In a forum of overclockers I figured it was worth reporting my findings. If 99 people find it useless I'm glad it could help direct at least someone. It current trend with the "false ASIC" readings and the ability of the card to OC was too glaring for me to ignore despite knowing gpu-z was not currently fitted to give us ASIC scores we are familiar with

Hey guys do we have a solid custom bios yet for these babies to unlock the power limits and some voltage + remove Boost 3.0 ? I have my Asus ROG Strix OC 1080 and i see that there is a bios from Dancop that doesn't look very appealing at the moment. Is there anything else out ?

Grats. Lets us know your clocks and voltages. I wanna see how more of the higher end offerings stack up to the FE's. IT feels like there is an artificial wall in all the bio's that keep them from going higher. I mean even the Zotac amp extreme that jaystwocents hit a wall hard a card that i did not expect to. Almost like Nvidia is saying "Hey new contract you wanna use them then you have to put this in your bios." IF thats the case i really wanna see how well they do when we get rid of that. But so far the Strix bios that "gets rid of the tdp" sucks and hits a wall even harder. It displays higher clocks but i dont think its hitting them because there is no improvement in fps from 2ghz to 2.2ghz. So who knows what they are doing i would really like to see whatr some of the higher cards that have more power phases can do but right now were not even topping out the stock FE's power.

I mean the 1080 is fast. Really fast i love it. Buit it feels like its got a weight tied to its let. It feels like it could be so much faster but nope nothing. We just need time to get a proper bios and really let the 1080 stretch its legs.



Anyways let me know how it runs. I was looking at one of them but microcenter only had one in stock and thats a hour drive for me and the way they sell there it would of been gone and bestbuy had a fe in stock so i just picked up the fe. Regretted it until i got the waterblock on it. Now i love it.
