I finally got EVGA gtx 980, but it has asic quality of only 63.3%. I could barely hit 1450 boost clock eventhough I set the power limit to 125%. I heard most people would easily hit 1500mhz. I feel like I didn't win silicon lottery.

Well, just setting the power limit higher isn't going to increase your clocks unless you're throttling for power draw. Even there it is only going to put you at your normal boost clocks.

I really don't understand them using ASICs below 70%.
maybe they do it just because most of the user never look at it and don't OC.

A lower ASIC isn't necessarily a bad thing...?
IIRC a lower ASIC will OC higher but require quite a bit of voltage.

b Die are very expensive. Why would you throw away a perfectly good GPU just because it doesn't overclock some arbitrary amount? ~20% over stock boost isn't that bad. It isn't because users overclock or don't look at the ASIC scores. It's simply profit.

Wait wait... ONLY 1450??? thats just 50 mghz away... I really don't think theres much to complain about here.. Thats fantastic! I bet that card is a beast! Sure 1500 is cool, and really high grade, but I doubt its really that important when you're already so close. Some people aren't even able to get as high as 1450, I'd say thats a realy loss.

Cheer up mate - running a GTX 980 @ 1450MHz puts you firmly into the top few percent of users worldwide.
A few more MHz is really neither here nor there.
In that sense, you've already won the silicon lottery.
So long as you're running stable - cool & quiet - I wouldn't worry too much about the numbers game.

I don't understand, what manufacturer should do after everything finish, to unbox package and throw in garbage everything under 75%,
sell for half price. ASIC Quality become something last few years. People pay graphic card and stable operation on fabric clock.
Only higher class should be tested good no matter on ASIC.

it's something they introduced themselves Vlada011, we the user did not make the situation as it is now. the manufacturer started advertising with OC capabilities and they introduced the ASIC quality to us. of course they did it for profit as a buying argument for us, now when we start to expect it are we the user wrong?!

Running furmark, my core clock stays at 1437 MHz. I checked what it was in Metro 2033 Redux, and it stayed at 1367 MHz. Memory clock stays at 1825 MHz in both cases. This is with a +96 core clock and +145 mem clock in Afterburner.

1437Mhz sounds fast enough to me. If you have time, run GPU-Z and take a look at the clock numbers at the bottom. You'll have 2 sets: one is your default settings and the other your overclocked settings. These are from my GTX 970 SC (04G-P4-1972-KR) so you'll have something to compare to: GPU Clock: 1290MHz - Memory: 1903MHz - Boost: 1429MHzDefault Clock: 1140MHz - Memory: 1753MHz - Boost: 1279MHz

Yes asic quality matters, it is now even in Wikipedia explained that maximal boost depends on Asic quality, see please article http://en.wikipedia.org/w...phics_processing_unitsSice manufacturers advertise overclockability as one of main features and advantage over other manufacturer product and because manufacturers provided for reviews cards that boost over 1500Mhz, card that does not meet this quality is subpar and should be sold for discounted price. I would personally return that card, also because if you want to sell it after one year or two buyers will ask how overclockable is that card and YOU will have to discount massively your card.

Hmmm....I don't think so. The reference numbers are established, and other (faster) cards clearly state their base and boost numbers which are higher than the reference. That's what they advertise, that's what you pay for and that is what you get. I haven't seen any maker advertising overclocking potential past these numbers - that's entirely down to the user + all the other components in an individual's system.

The reference numbers are established,
With GPU boost architecture nothing is established. Two cards with different asic quality will have different boost clock because asic quality determines maximal boost and maximal boost is variable that is important (and not some base clock). If one card has e.g. asic quality 60% and second card 90% difference will be big. Card with lower asic has lower resell value, currently I want to sell gtx 780 and everybody asks what is asic quality, with lower asic quality people will pay less for card.

Not quite sure why they sell for less. Then again people tend not to be too smart and assume that higher automatically must mean better. Had 2 GTX 770s and the lower ASIC (10% less) overclocked markedly better than the card with the higher ASIC. Of course voltage was a factor.

ASIC = Application Specific Integrated Circuits. Circuits that are hard-wired to do what they're designed to do. Every single chip in your computer is an ASIC. A GPGPU is a GPGPU. A CPU is a CPU. Every chip is cut from a wafer and some are better than others.... determining the quality is called "binning". Not sure how GPU-Z is determining the ASIC quality here though. The ASIC level refers to the electrical leakage level. Higher leakage, uses more current, lots more. Low leakage less voltage for the current clock speed. A high ASIC card would use less voltage to run at the stock clocks. On air you want the highest ASIC card you can get. On water you want something around 74%. 60% and under is for liquid nitrogen.

here is what my cards are GTX 770 = 86.5% GTX 750 TI = 65.9% 2 x AMD R9 270's = 66% and 65.7% so based on these results it seems like mid 60% range is the normal most of the time, if ya have higher then that you are lucky.

Maybe you will maybe you won't its unknown, my 2 x MSI R9 270 are on air coolers and at 66% and 65% they both overclocked from 955/1400 to 1100/1500 just fine.

So I gave in and returned my EVGA gtx 970 SC ACX 1.0, and in exchange I got an MSI GTX 970 Gaming 4G. Best decision I have ever made when it comes to computer parts. My EVGA card had so many issues that it was unbelievable. I can't even believe they sold those things. The issue that was the last straw was that my EVGA card was throttling all the way down to 1367 MHz core when playing demanding games or benchmarks. It was also very, very loud and had coil whining. The asic on that card was 62.8%. The MSI card that I got does NOT throttle at all! It is also 5 times quieter than the EVGA card that I got. I haven't tried to get a max overclock on it yet, but so far I am running at 1528 MHz core easily (the only adjustment I used in afterburner was +200 MHz on the core). The asic on this card is 72.7%. I am so glad that I returned that crappy EVGA card and got this card. That was the first EVGA card that I ever owned, and it will be the last. EDIT: I think I found a max stable overclock with no voltage adjustments. It is 1520 MHz core and 7806 MHz mem. This MSI card rocks. So EVGA was 1367 MHz and MSI is 1520 MHz for me. Now that's a big difference. EDIT: I increased the fan speeds a bit and now it is stable at 1528 MHz core and 7806 mem (+200 core +400 mem).

Derp. I'm stupid. I clicked a link that Sajin put on a different thread and thought I was on the same one. Ignore this: Oh just saw Sajin's post about ASIC. So the higher the ASIC the better? I swear the other dudes were just saying it's better for it to be lower? Unless I read it wrong
