'm putting around 12 pieces or so through the ringer right now. I can say the memory clocking is really something else on this card. About every card did 2100mhz stock voltage, and with more fbv (NDLR : FBV = frame buffer voltage je pense, donc vmem ) (#FF0000">yes it scales like crazy can do up to 2250mhz on some cards D . I pushed this one with about 1.8vfb for some nice fs scores, and they are going up with memory mhz so its scaling right. The memory overclocking is big part of what this card is about. Here some screens from yesterday, the memory is really fun to play with on this card. Overclocks like a bat out of hell. Not bad nearly 10.4k Firestrike extreme on air cooling (54c max temps!) and around 1540mhz core

Also did you see that the card #FF0000">using samsung memory?
AFAIK, that is the only 980Ti on the market using samsung memory. Samsung memory is THE choice for overclocking, no doubt about that. 780Ti KP had sammies as well. |

Well, the ASIC stuff is interesting right. I tested around 15pcs on air cooling.
From lowest bin to the highest bin. Almost all KP980Ti seems to be clocking at around 1530-1590mhz at default voltage (around 1.16v). Higher asic cards will be the higher clocking ones, lower asic cards are at the lower end of the range. There are definitely exceptions, not all gpus go like that, but most do. ALL KPE 980ti are binned gpus , even the lowest asic level base card is still capable to hit 1520-1550 usually or more. That's the air part of asic. Its pretty consistent, but there can be rogue gpus. The LN2 part of of ASIC value is that higher asic cards clock higher on LN2, have more leakage which will helps with cold problems, and have better memory controllers(highest memory clocks). ASIC value really applies to LN2 the most. On air, it can help with maxwell because you cannot add additional voltage at ambient cooling. Highest clocks at default voltage almost always on higher asic gpus. This is what makes higher asic better on Maxwell than previous (Kepler could scale voltage on air, so lower asic was better). Lower ASIC % in the past (pre-maxwell) was the best for raising voltage on gpu at air, because there is less leakage on lower asic gpus. Less leakage = less heat/less noise and also the ability to increase voltage. |

Based on the comments in the thread, maybe best its best to let you guys know(who don't already) a little bit about what ASIC is and how it relates to this card or any other card for that matter past or present. I'll hang out here a bit and check back often to answer any questions by OC.net'rs about the card, ASIC, pricing, air performance, ln2 performance, ANYTHING smile.gif. I would rather respond with the correct information directly to someone, than see that person repeating the wrong information. They haven't started selling just yet AFIK.. Ill answer some of the questions I've seen asked already to get a start. ASIC is not a new "measurement" , its been around for a very long time. Only just recently is it available to be seen through public utility though(gpuz). It represents a few measurements on a GPU, not just one as many think. Basically it measures the performance ability of a gpu at a given voltage. There is another measurement of leakage as well. These two values represent "ASIC" as you guys know it. Without talking about numbers or percentages yet, higher ASIC quality means a GPU will require less voltage to run at say default specs. What does this mean roughly? It means that this GPU is using less voltage and is generating less heat per clock than a lower ASIC counterpart. HOWEVER it also means the voltage limit of what it can take on air as well as the voltage response getting weaker/noisy. Here comes the leakage part. Highest ASIC gpus have also have the highest leakage, low ASIC gpus have lowest leakage. The two values scale linearly. This is why the lowest ASIC cards are the ones that can take loads of voltage on air, and the response is good. Usually these low asic cards can OUT OVERCLOCK their higher asic counterparts because they end up scaling higher on clocks maxed out with the benefit of the voltage increase that the high ASIC cards cannot. They are stuck on lower volts because the leakage is already very high. How does ASIC relate to air overclocking? Typically a higher ASIC gpu will overclock nicely on default voltage/air cooling, yielding highest overclocks WITHOUT any voltage increase. Less voltage/less heat. Lower ASIC gpu will need to use more voltage for a given clock as the higher ASIC one. Back in the Kepler days, this meant great air/water overclocking on our 680's and 780's. I remember posting a thread at evga explaining to people that they needed to use 1.4v+ (at dmm) to max out their classified gpus on air. God I miss those days smile.gif. Back then, the best gpus on air/water were the low asic ones, they could always oc/ov the highest.#FF0000"> Times have changed, and this doesn't apply to maxwell however. #FF0000">How does ASIC relate to Maxwell Air overclocking? With maxwell gpus the above definitions of ASIC do not apply Well you guys know maxwell 980,980ti, titanx have ambient cooling voltage limit on what v's you can give it on air/water. That's just the way it is. Its been proven over and over on every single manuf brand 980,titanx, 980ti. kp980 owners as well, no different. These gpus don't like voltage on air over 1.22-1.23v usually max. Just green garbage all over the screen with more, no better clocks. Best clocks usually achieved with stock voltage or maybe slightly higher. So given what we know about ASIC quality and the voltage scaling capability of 980,980ti,t-x on air/water(NONE), it indicates the best gpus on 980Ti, will be the ones that can overclock the highest on default voltage or near default voltage. Ever noticed why almost every single review of 980ti (any brand) is around 1500mhz? The reviewer never can never add much voltage for better OC result. I'm mostly an Ln2 person, but some users complaining about 980kpe not overclocking on air prompted me to try and make a better bios for ambient that would allow voltage. I managed a slight improvement that works on some cards, that's about it. But I learned a lot about the scaling of Maxwell on Air during that time and how we could if anything improve on this with KP980TI. #FF0000">How does ASIC relate to LN2 overclocking and more specifically kp980ti? As explained above, higher asic = higher leakage. Leakage is actually a good thing and can be contained on LN2 cooling. Cards with more leakage will run a bit hotter, usually extending cold limits on gpus and getting more core MHZ on LN2. Every overclocker wants every last mhz right? Higher ASIC GPUS also have better memory controllers and typically can overclock the memory very high on LN2. Lower ASIC gpus usually are not so good at driving the memory on Ln2 and the overclocker will lose a lot of MHZ when going cold. Lastly, every serious overclocker knows the highest ASIC gpus use the least amount of voltage for any given clock. This means these gpus will always have the highest potential for scaling to the absolute highest clock on LN2, because most 980ti gpus max out around the same voltage level on the high end max max ln2 as well. Wouldn't you want the most clock you could get for that voltage smile.gif. KP card pushes them all the way. Unless its a lemon gpu (cant test every single one on ln2 lol), it will max out on this card. #FF0000"> Does high ASIC guarantee highest clocks on air? NO. The other part of ASIC which is Leakage is high on these, so that can actually hold back some high asic gpus on air. This doesn't mean its bad on Ln2 as well, and usually the contrary. I Tested around 15 pieces or so of KP980Ti these days, all different asic levels. Some as high as 81% all the way to 64% (which we wont even sell smile.gif the average clocks on air were roughly 1550mhz Lowest was 1526mhz, highest was 1592mhz . Seemed like every card went to 1539mhz or so smile.gif Most of the higher asic cards did as expected and hit the upper 1550's. None could pass 1600mhz, but some came really close! Those were mostly higher ASIC%'s. You should know that every kp980ti is binned gpu and even the minimum ASIC level for any card is very high compared to average. A 70-72% asic card is a great card. Reviewers should be hitting low to mid 1500's on avg and some cards hitting close to 1600. If your an air/water guy and don't plan to run ln2, I think no matter what asic level of card you get, it will do mid-low 1500's and there is a chance on all kp 980Tis regardless of asic to hit the magic 1600. Still need some luck too, leakage can limit this. For the hardcore users or the ones that may run ln2, I would think more seriously about asic and the time/money you can save buy getting something closer to what you want. Being an Ln2 overclocker myself, I feel this buy is mostly for you. #FF0000"> Does ASIC % guarantee highest clocks on LN2? No it doesn't, it is only an indicator of what to expect. EVGA is giving the chance for customers to zero in on exactly on what you want. Some users will try many cards to find the highest asics for best LN2 overclocking, its not a new thing. The highest ASIC gpus will almost always be the best ones on LN2 as explained above. These are the users we mostly are targeting with this. The ones that end up buying and trying lots of cards to find the one gem, almost always a high ASIC card. They will end up spending much more than the price difference of kp980ti high asic and wasting lots of time in the process. This is geared for them. Are we binning gpus away from other cards to make this one (classy or other)?. LOL I wish, but no way that's possible or anyone would even let me do that haha. For sure there will be guys on classys or other cards who find a high asic gpu here or there and im sure they will let us all know they paid XXXX lower than what someone paid for their KP and still got a high asic. KP980ti is very special card in many ways hw wise. This is just one special added buying option for our more hardcore users on first few batches directly from us, that's all smile.gif Anything I didn't cover or you want to know something specifically about the card, I'm happy to answer. |

Good question, let me make sure I got it right. So your asking if you buy the 72% bin, can it be just as good as one of the 76% bin ones? Absolutely. It could for sure be better on air. On Ln2 though, the asic has more meaning so I'd place my bet on the 76% there. Keep in mind the difference could be minimal but still there, all gpus are so different really. We chose 72% as the lowest for this for a reason. Those gpus are still very very good and all 72-80% have big potential. Higher asic has its value for sure in extreme overclocking for many reasons. 72% asic cards can still hit 2050mhz, I've done it. 80% asic card can fail to hit 2G, did that too smile.gif. Those cards are exceptions of the norm that i see tho. Let me show you some data from the cards I tested on air. We sample from each batch to check quality level. I tested 4 pieces 76- 80% asic level they did 1592,1578,1551, and 1532mhz roughly max firestrike ultra on air 100% clean 54-57c So compare that against the 4 74-76% asic I tested that did 1578,1552,1539, and 1539mhz. Then I tested 4 pieces 72-74% asic and I got 1552,1539, 1539,1526mhz. So highest OC Mhz at default voltage trends downward with asic like this. I also tested some lower asic gpus(well below the spec for this special intro asic buy) 63-64% asic on kp980ti long ago. They went something like 1520,1500,1500,1483mhz. I would usually not bother with a low 60% asic card on LN2, but still useful testing regardless to see it as I already know the behavior and what to expect. The ranges they are offering I think are 72-73.9%,74-75.9%, 76-79.9%, 80%+. You will get exactly somewhere slightly higher or lower in the group you purchase from. 80% are gonna have the best chance to be awesome on Ln2 and even air, but with air cooling results on these can be mixed due to leakage factors. These gpus are VERY rare as well, so extremely limited availability on 80%+ ASIC |

finalement après avoir essayer de pousser la 980ti amp ,et assez decu de sa montée en fréquences ,avec les ventilos à fond 73 degrés pour un oc moyen,je l ai renvoyé
Et la j ai une ACX 2.0 et franchement elle envoie ,avec les ventilos à 70 % et franchement OC 73 degrés :1520 au boost et 1930 à la mémoire,ca passe nickel.. Du coup vu que je l ai eu à un super prix ,j y ai collé un accélero xtrem IV dessus et la silence et temp max 55 degrés ,ca se trouve elle monterait encore la bestiole |
