EVGA 980 ti SLI-Save some money! Buy reference/stock

But.....but.....spending $30 more and I can put the 'eff tee double you' in my sig. Totally worth it. God my e-peen is poking out the window.
 
I have a middle tower case, a LianLi PC-7FNWX with a 140mm intake and two 120mm exhaust.
The two exhaust fans are mounted in push pull over the Corsair H80i GT AIO.

My CPU on summer goes up to 80C with the two GTX980 SLI reference blower.
Now I upgraded to a GTX980 Ti SLI with the EVGA ACX 2.0 open air cooler and I'm quite worried that my CPU temp will increase by 10C.

What do you think on this? Will this two cards increase my case temp by 10C and conseguently on my CPU?

My case has excellent airflow but my cpu temps went up 4-5 degrees in Crysis 3 with the MSI Gaming 980 Ti as opposed to the reference blower Evga 980 Ti SC I had first used.

what do you mean for excellent airflow? what CPU cooler do you have? +5c on a quad core?
and you have one card, I think that for my CPU is downclock time :(
 
oic, hmm reference with upgraded cooler...

Is upgraded cooler free or what?
 
OP,

You're confusing me. You say buy reference/stock even though yours are NOT Nvidia reference. They use an aftermarket cooler.

FYI, this is reference:

lol the reference blower is anything but silent on GM200, not if you want decent temps at least

with the reference blower I had a SLI of 250W cards without problems with only two case fans,
with GM200 SLI (250W either) I need at least 4 case fans.
 
One thing worth mentioning is the Superclocked 980 ti with backplate costs exactly the same as the base model without the backplate. So it's basically like buying it with the backplate pre-installed.
 
Because Classified and KPEs have much better build quality. Try sending 1.8v to the GPU (w/ LN2) on those reference cards and see how many seconds it takes for the VRM to burst into flames.
 
Just to update my old thread as it was resurrected. I have been happily using my Reference 980Ti's with the EVGA upgraded cooler running at 1485 on both Gpu's and enjoying gaming. No issues what so ever.

Again to my point...I agree that the Kingpin'Classy may look better and build quality with all that copper on the kingpin looks really nice....BUT...I paid $649 for each of my cards.

You state "Much better build quality." Seriously though, I have yet to see a Classy/Kingpin 980Ti push over 1550 on the core. So, that "Build quality" you state nets you what? A whole whopping 50-60 MHZ on the core? What's that amount to? Like 2-3 FPS maybe? Like I said in my initial post on my thread. If you want to spend the extra cash$$ then by all means go for it... If you are going for LN2 and record breaking, of course it's a given that I would opt for the beefier PCB's like the Kingpin. Kind of pointless though to spend all that money on that beautiful copper Heat sink just to rip it out though....But again I digress

Yea, after going through two series, 780/780ti classifieds which I OC'd to the max, I chose to sit out of buying "enthusiast" grade due to the lack of actual gain in FPS.

Yeah, I hate it when I'm gaming away with LN2 and my board combusts due to cheap PCB quality. Messes up my Hairworks in Witcher 3... :p

LOLz-Quoted for truth...

That's y you have to disable Hair works AA if your rolling with LN2 and cheaper reference PCB crap...

Apparently long enough to finish an LN2 Firestrike run: http://www.kitguru.net/components/g...titan-x-hits-2ghz8-2ghz-with-liquid-nitrogen/

Unless you want to tell me the Titan X ref PCB somehow has "much better build quality" than the ref 980 Ti PCB.

Now with that out of the way, I don't disagree that Classified/Kingpin cards have a better PCB with much more robust power delivery. But unless you LN2 bench everyday, those extra phases and PCB layers won't do jack for you, especially more so for Maxwell since voltage scaling is non-existent until subzero.

Except you aren't gaming on LN2. Even on water, I wouldn't be comfortable with sending over 1.4-1.5 v with a reference card. 1.5 won't blow it instantly (as long as it is cool), but it will push the VRM extremely hard and do long-term damage.

is there the possibility to flash the Superclocked bios to the Stock cards?

Yes, but make sure the stock cards can OC high enough, which shouldn't be a problem, to meet the needs of a superclocked bios...Otherwise it will keep crashing

Ummm, my post was 100% Sarcasm? As in, since nobody games on LN2, why would we care whether the VRM on the card could withstand the voltage?

The OP's point was that Maxwell has inherent limitations that limit all cards to similar overclocking levels regardless of cooling, except for LN2, which is only used for e-peen, not gaming, so why pay extra for useless premium build quality?

Except ref cards (and any custom card that uses the ref voltage controller) are hard locked to 1.274V. Without physically modding your card you won't ever go over that voltage period so that hypothetical scenario would never happen.

Bingo!

Unlike Kepler where more volts = more overclock, Maxwell simply doesn't work that way and doesn't scale until subzero.

Because even voltages over 1.4v stress the reference VRM. A good watercooling setup can handle 1.4-1.5 V.
And have you ever heard of a device known as a Peltier. A peltier is a shims that can cool the GPU to sub-zero temperatures. You put it over the GPU die, below the waterblock and plug it into a molex connector. It's like 24/7 LN2 or DICE.

Yet another reason to get a Classi or KPE: voltage over 1.6v is possible in software.
 
And yet 1.6v doesn't mean jack shit unless you're at subzero. Seriously you might want to do some reading on how Maxwell is different from Kepler.

As far as peltiers go. Please run the numbers and tell me what the total heat load (including that from the TECs) is if you want to bring a 350W GPU to subzero, how much raddage you'll need, and how much extra power those TECs will be sucking down. And also how you plan on dealing with the condensation issues for running the GPU 24/7.

Right on..

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. Times have changed, and this doesn't apply to maxwell however.

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.

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.

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.

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.
