I got 72% and 74% ASIC models. Latest drivers and windows 10 with everything on system up to date. 750D case with two fans infront (inflow) and one at back (outflow) and two top (outflow). All corsair silent fans with pretty decent airflow.
Motherboard is R5E. CPU is 5930k with Noctua heatsink and fan. OCed to 4.2Ghz and tested for stability through realbench with 8 hour runs multiple times without issues.
Anyway, The cards on stock settings boost to 1404Mhz. So far most stable OC was with following settings: 130%/87C/+50/+150/0 mV (cards set to OC BIOS) with custom fan profile peaking to 80%. This gives 1430Mhz boost clock and 7400Mhz memory and top card hitting 88C easily while the bottom one does 78C in heaven/Firestrike Extreme/Ultra.
Pretty sure I can get similar or better results with an SC or SC+ model...
I was hoping for atleast 1480Mhz/7800Mhz OC (being pessimistic about this) and still was disappointed.
Any suggestions or is this RMA material?

You need to remove and test each card individually. First, you say latest driver? Is that the hotfix driver listed on the forums or the latest suggest by Windows and NVidia? If it isn't the hotfix, sli is known to have issues. If you are on 355.80, with the sli hotfix enabled, then you should test each card by itself. According to everything I have seen so far, these aren't performing all that impressive on air... Oddly enough, they aren't over built to be used on air, but the cost and base clocks make people want them. If you don't have the hotfix: http://forums.evga.com/m/..aspx?m=2384654&fp=1

88c and 78c are too hot for these cards to overclock much. i hope you werent expecting 1550+ on air with such high temps.
no this isnt rma worthy.

if you want your cards to overclock higher you have to get the highest temperature around 65C or under, its as simple as that. increasing voltage wont help, increasing power target wont help, praying to the overclocking gods wont help. the only thing that will help is getting better airflow to the cards. better COLD air flow. just flowing hot air over them from inside the case isnt going to do anything. get more cold fresh air into the case, increase the fan speeds on both gpus, increase the hot air being exhausted out of the case. your overclocks will go up. its simple as that, sorry it sounds like im trying to be mean here but im just trying to help. increase fresh cold air coming in. increase gpu fan speed increase the amount of hot air being removed from the case. increase your overclocks increase your fps

I appreciate the responses guys but as I said, I was expecting a very low overclocks to begin with. This isn't it. You make valid points though. I will swap cards to bring the higher ASIC card to the top to balance things around. As for airflow, I totally agree. I managed to run a full Firestrike run with fans set at 100% keeping the hottest card at 68C. Not practical in terms of noise but confirms your point.
Just not seeing the worth of kingpin despite better aircooling vs SC/SC+. I could have gotten the same with those cards. Only difference so far is that I paid 150 + 200= 350$ on top for practically nothing.

But, the card isn't made for air. Keeping a SC or ssc on air will give you great performance, because it doesn't have a ton of extra phases and such creating extra heat to dissipate. The classified and K|ngp|n are meant for below ambient overclocking, which is where they shine. They do work on air, but colder is better.

Isn't made for air but sports a full copper heat sink? Advertized as both the best either way; air or water? By the way, the setup can't be stable OC'ed at all in Witcher 3... So zero overclockability now...

the cards really do shine when frozen, they just so happen to be able to be used on air and water as well, but if youre spending $850 + just for air cooling, you did it wrong. you should have gone for some superclocked ACX cards for $650 each instead and saved yourself some money. All that extra marketing stuff on the kingpin page really does only apply to people who can keep the temps at 25c or lower under load. Its a good way of getting more cards sold to the uninformed by evga.
try overclocking the cards one at a time with 100% fan speed, if you cant get at least 1500/2000 on them then you may have gotten dud cards.

I wrote above that I can do 1500/8000 at 100% air but obviously that is not practical. Ofc, this is only one regular firestrike run, who knows how stable it is.
Anyway, I guess air overclocking is pretty much dead overall. Good thing I just upgrade every 4 years so I'll roll with this setup until then. More than enough punch despite so much money thrown to waste...

You know, it isn't clearly indicated that is being the case which is the issue. I guess I had to dig deeper to find out.

I would say get a H2O AIO cooler like a Kraken etc... but if your ambient temps are really high to start with it wont do you too much better than air cooling. Not enough to justify losing the money anyway. Whats the case your using and how is it setup?

Experiment: Take the side of your case off and put a box fan next to it on HIGH. I'll bet you $20 PayPal you're temps stay much lower without forcing those ACX coolers to 100%. Now, play with your overclocks. Summation: One ACX cooler in a chassis circulating its own heat is fine. Two, uh uh no matter how "efficient" you think your chassis is. TL;DR Going through 3-way 470s, 570s, 580s (and then HC versions) and 680s, I can tell you that "Rear-Exit" exhaust cards rule over any of this ACX funny business when dealing with 2 or more cards and GPU temps. I say that after my 780-series foray. Went from stock rear-exit coolers of 2x 780s, to ACX coolers add-ons, to 2x ACX Classifieds, to 2x K|NGP|N w/ACX and finally landed on my perfect babies: 2x Titans, first batch made of serial #42 and #43. They came with additional ACX coolers, serial numbers #11 and #12. At first, you'd think, "ACX coolers! Yes, has to be them for best cooling!" I'm hear to tell you that ACX, or any design that "dumps" hot air into your chassis, is OK for 1 GPU - but not 2 or more. After extensive testing and tweaks tot he ACX coolers (replacing all thermal pads, thermal grease, etc). I decided to try out the stock reference coolers. Well, they did run a little hotter *easier* but my ambient temps were back to normal! So, I removed the reference coolers and modified them like crazy! Now cooling the VRMs, the rear memory, the rear of the VRMs (backplate) and added heatsinks onto the backplate. While the noise is still there with the fans getting up to 60 to 80% on my custom fan curve, it brought my temps way way down enough to get the highest stable overclocks ever. Hell, I've even mined Altcoins on them for months. FYI, that's 95C temps with voltage as low as they would go, for 3 months straight. Who here can say they mined Bitcoin on Titans? lol I did, and made a tidy profit to pay for the Titans! ACX coolers were a joke to even try mining. Mining runs the hottest temps you'll ever see out of your cards. My chassis? Dell XPS 730x. It has 2x 6000 RPM High Pressure PWM server fans in the front. I actually added a 3rd 6000 rpm high static pressure PWM fan, same one, to the rear just under the GPUs because of how high my chassis ambient temps were. My chassis' temps would rise upwards of 50C. I swear I saw > 61C ambient chassis temps towards the rear at one point with the dual Titans and ACX coolers (this was because I left my office under stressing the GPUs, only to come back to 33C inlet air temps cause my office was cooking!)! I have 5 temp sensors through my chassis. Inlet is always around 21 to 24C usually. Now, you have to know a bit more about my setup... I run a custom BIOS that I get to force the Titans to 1202 Mhz and 200% Power Target (boost is disabled), as well as forcing LLC. Two Titans alone under stress test pulls around ~950W from the wall with no CPU usage (@ idle, system pulls 135W). Yep, I'm getting ~425W out of my babies which is REALLY REALLY hot.

get your temps lower and your overclocks and stability will increase, its as simple as that.

It didn't do much on the 980 except cost substantially more and make the card stable at stock temps. Spending another $150 per card is only a waste of money just to get a few more Mhz. We fell for the hype, and you know it.

Try using the 353.62 driver, that one works the best for me on W10 pro with SLI 980 Ti KPE(75.1% & 75% ASIC). This driver also gave me the highest stable OC ( 1531MHz in SLI ) and my best score Fire Strike. I have tried all of the newer driver's and they either crash the test or lower my score, you may need to try them all to see which works best for you. Do not just go off of one driver test, there may be a better one for your system.
Your temps are much higher then my 2. I would check the paste on the card's to verify it is applied correctly and has enough on them, also try removing your cases side panel to see if that drops the temp, like others have mentioned.
OC'ing the KPE or any other GPU takes a ton of time and effort to find the max stable OC, don't give up so early. I have had mine since 2 days after the release and I am still working at improving my test score's.
If you need any more help I would be happy to try my best, there are also many people here that are very helpful when people are having issue's.
BTW I am using both on air for now.

Wow, overnight and so many replies. Thanks guys, so much information to dig through.
lets summarize some facts here based on replies:
- Case airflow/temperature matters ALOT in air cooling.
- ACX is rubbish for SLI. EVGA should have provided alternatives on this matter.
My case is a 750D and I have a windowed side panel. I really want to install a 200mm fan on the side but can't find a replacement side panel with mesh and fan. I do not wish to buy tools to do a custom side panel unless it is my only solution (well, other solution would be to buy a new case! YIKES!).

Quick Update:
Card at default settings and clocks with 83C limiter.
Firestrike Ultra Demo:
Case Side Panel Closed = Top card hit 83C and started throttling hard from boost 1404Mhz to 1304Mhz towards end of Demo scene.
Case Side Panel Removed = Top card hit 83C and started throttling hard from boost 1404Mhz to 1320Mhz towards end of Demo scene.
Hardly a difference frankly and still the fact remains that the card hits insane temperatures even on default. So it isn't the case cooling as it seems to be slightly worse than an open case.

If using SLI on air, consider having an airflow fan on the side panel which can make up to a 10 degree Celsius difference in some cases. Front intake just won't do enough. But of course that's not easy since the OP has a 750D case (not sure if that side window is good for modding?).

My KPE's had a terrible TIM application from the factory, way to much, the simplest thing you can do is remove the heatsink clean the gpu and heatsink and apply some good TIM in the correct amount. Other than that cut your side panel and install a fan as you suggested to get better airflow

I just ran the same test as you with my two kpe for you to compare the results. I do have a 200mm side fan on my case, so I disabled it to be closer to what you have with the 750D. Card at default settings and clocks Room temp was 22.7C/73F Firestrike Ultra Demo Case Side Panel Closed = Top card hit 76C and boosted to1430Mhz. Bottom card hit 65C and also boosted to 1430MHz. Case Side Panel Removed = Top card hit 74C and boosted to 1430MHz. Bottom card hit 64C and also boosted to 1430MHz. Overclocking both card's to 1506MHz core and 1953MHz on the memory only increased my temps by 2C with the side panel on. I did not run this test with my max OC of 1531MHz, but I think the temps would not change. I would be taking a look at the thermal paste and replacing it with something better. I normally do that with all of my card's ( have not had time to reapply the tim on these card ) and in most cases it drop the temps by a few degrees.

Re: 980 Ti Kingpin SLI won't overclock much

Interesting I'm in the middle of putting mine together with 2 kingpins I was already expecting this kind of out come so I got a case that moves a **** load of air in and out with 140s and 230s for fans the biggest case I could find without going custom 25"x26"x9 4 230mm & 5 140s. I got my Kingpins because I basically was looking for something that performed like a Classified with the bling,I think it is fair to say I found or exceeded that. There are a lot of things that can through it for a loop [ I found ] rez. & refresh you're using, most defiantly heat no 1 [ I'm going to experiment with my mobile AC unit I have ] ,the mother board it self, anything causing a bottle neck in your set up, from what I've see and read they like to use the power I went over kill on everything in mine I don't want any bottle necks or heat with in reason of coarse. I got a Evga 1600 to run my board & video cards in SLI then I will use my 1000 ultra X4 to run my fans and anything else I through at it,my video cards will be in reverse meaning at the top of the case instead of the bottom. May go flat in the future like a horizon 10. I like the idea of changing the thermo paste I have some Arctic MX4 I will try. There is a lot of good info & ideas on this post you should check into it I'm going to use some if not most of it to get the best result. The only other answer is liquid cooled. Here is something from the Kingpin web page to take note of. Voltage in relation to power consumption and
temperatureIncreasing voltages and improving the cooling to reach max clocks, this is basic overclocking. Keep in mind increasing voltages always brings an increase in power consumption and internal GPU temperatures. This is not a linear relationship, but more like an exponential one. When you increase voltage 10%, your power usage and temperatures will not increase just 10%, but more like 25-30%. This is very different to frequency gains, which are more linear (10% faster clock gives close to same 10% power increase). Even at extreme cooling temperatures, this rule still applies because -100 °C at die contact surface is still not enough to cool down heavily over volted chip logic structures buried deep in the silicon. It will still overheat at one point no matter how cold temperature is, if voltage and power consumption is too high. This behavior is important to know, as it is the basis for all overclocking, extreme or not.

My room temp is 74-75F. No way I get the same temperatures as you do! Note the following: - Air cooled CPU - x1200i PSU fan facing down - 2x 140mm front fans inflow. - 1x 140mm back fan exhaust. - 2x 120mm AF top fans exhaust. I opened front panel (none airflow edition) and temps went from 84C to 79C on top card with fan curve reaching 90-100%. Already ordered a 750D Airflow Kit and should arrive end of this week. By the way how is your fan curve? Can you provide details on how you modded your side window? Thanks mate for your replies!

Does 70MHz really make a difference in games? Between 1404 and the 1480 OP was hoping for.

I use the aggressive profile in PX. I did not mod my side panel, it's a Cooler Master HAF X. I just meant that I disabled the 200mm fan to be closer to your 750D case and to narrow down the issue with the high heat. That air flow front base should help out and give you better cooling, that was a good idea if you are not plaining on water cooling. But I still think you should check the thermal paste on both card's, just to be safe. You could also try adding another fan for more intake. Like mounting it to the hard drive cages so there is more air blowing straight onto the GPU's.
