your interpretation of GPU Boost varies from partially right to completely ridiculous.
same with your attitude about peoples concerns shared here.
if you don't respect peoples concerns then you should probably just stay away from such topics.
instead of blaming people they would complain for nothing all the time.

It is just that that GPU boost has different steps at different temps. What is weird is that why the first step is at around 63C or so. And that is the question here and what the OP is trying to ask. It is not about the usage or anything like that.
I also think that it is stupid that the first step down is so low considering temps. If I were to decide I would not let the temps determine the steps before 80C or so. As far as I see it there is now reason to start decreasing the clock speeds at those temp, even by just 20MHz. It does not have much impact on the performance but is annoying. :/

no no, everything is working perfectly fine just like it should so we are the problem and should just stop complaining.

to design a card with zero fan speed until 60C and to trottle it down at 63C right after the fans started spinning, that's just crazy.
there is something going really very wrong recently.
I agree. This doesn't seem normal. Can any of you confirm that forcing a constant voltage in MSI afterburner does nothing? I tried using this force constant voltage option to see if that would stop this odd throttling but GPU-Z isn't reporting a constant voltage at all. It still fluctuates based on load and the card still down throttles a little. I had someone I know with an MSI brand gtx 980ti try this out and they had similar results in gpu-z, voltage still fluctuates. Wonder if this voltage is hardcoded to always change like this. Someone suggested they put it there due to timing calculations or something but they wouldn't need that if the card just ran at full clock speed in the first place lol... also I don't have a 980ti if I didn't mention that before, I'm having this exact same problem on a reference gtx 980.

Ok I just tested this again and it is definitely based on temperature and not power consumption. I monitored power usage with msi afterburner and it roughly stays at 104% in valley benchmark. The highest I saw it go was 114% and that lasted about 2 seconds. My reference gtx 980 (bios 84.04.31.00.80) still down throttled to 1493 from 1506 at 67-68c. Seems like its doing this with plenty of spare power left and to me, it seems to be based entirely on temperature. Gotta say it like it is, this seems like a pretty crappy unnecessary design. We should have the option to remove any sort of throttling based on temps.

1506 MHz down to 1493 MHz is a very small change. And still very high compared to the 1102 MHz base clock. I am not sure what you are complaining about. The GTX 980 TI Superclocked+ ACX 2.0 is rated at a 1102 MHz base clock and 1190 MHz boost clock. You are boosting 303 to 316 MHz above the advertised boost speed. But that still isn't good enough? If you really wanted to remove this "crappy design", the card would be stuck at 1102 MHz and throttle at 84c. Changes in boost speed is NOT throttling. Throttling is when core clock drops below base clock speed. Variations in boost speed are per design to keep the card within power limits, within stable limits for trouble-free use, and within limits for longevity for warranty reasons. It's about as logical as expecting the user to click one button and suddenly unlock the card from "crappy" 1102 MHz and make it jump up to 5000 MHz. It's not simply an option which EVGA or NVIDIA aren't giving you because they are mean... it's a limitation which must be worked around and compromises must be made in order to offer you a good reliable product in mass production. Be thankful of what you have. You have a card which is working better than advertised. Instead of being happy, you complain. Wow....

I didn't mean to get anyone upset here, but there is something "wrong". I'm not a novice computer or tech user in most senses. My old GTX 780 did not have this throttling issue even at extremely dumb overclocks in the same test environments I'm using assuming I maintained the heat threshold.
As far as numbers, I don't have the time now as I'm suiting up for my 2nd job (takes 2 to have an expensive hobby right?), but I can say this. The stock KBoosted core clock is 1290. I have seen it fluctuate all up and down based on load and tdp hitting 100-110 depending on power target. I have noted it going down into the 1050 range (below the advertised speed you're talking about). But this isn't the whole of the problem, rather it's that it shouldn't be jumping all around as it inherently may cause problems in applications which are tuned to run at the 1290 and then see lots of variation. Whether it be by design or not (referencing not seeing this with my EVGA GTX 780) it doesn't help anyone who's counting on a stable clock.
Like I said before I'll put some time and effort into solving my own problem I'm not just looking for a handout. I'll have a couple days off after today so I'll report back on what if any results I can yield.

It sounds like you may have an issue. My first advice would be to disable Kboost, uninstall precision, reboot your computer (after uninstalling Precision), and reinstall your video card drivers using the advanced -> clean install method. After doing this, please DO NOT install Precision OR Afterburner; please simply monitor with GPU-Z so that we can eliminate Precision or Afterburner as a cause of the issue. Give us more numbers and more details when you have a chance. Good luck!

If it was because of Temp you would see "Temp" as the reason. We will stop using the term "down clocking" and "throttling" for Ty_ger and use "boosts less" :) Technically he is right. I think the biggest impact on how the card boosts is the actual application using it. I'm not going to pretend to have even the faintest knowledge about programs accessing a GPU. When I watch a run of Firestrike Extreme in GPUz, it immediately hits one performance cap or another. VRel, VOp, Pwr. Different ones at different times. The boost runs between 1448 and 1502. When I watch a run of Valley, it also immediately hits a performance cap but it also stays at 1502 boost for 95% of the run. Playing Thief recently, the boost clocks are all over the place. From 900 to 1502 when it hits some caps and stops boosting. When its at 900 or 1200, there is no performance cap reason, the application simply ins't demanding more horsepower. All that being said, if you actually see "Temp" as a Performance Cap reason at anything less than 84C, something may be wrong. If you are not seeing "Temp" as the reason, its probably working as intended.

The 13MHz drop everyone is talking about in here is completely normal. It's been like this since GTX 680, the 680 dropped 13MHz at 70C, 80C, & 90C.

Okay I've figured more information out with this thing. 1. 68c is the trigger. 2. The down throttle is 13mhz 3. Voltage changes from 1.2180 to 1.1930 when this triggers at 68c. Tested this 4 different times, was the same every time. Looking in bios tweaker I can see something called GPU Clock Offset + 13MHz. Not sure what that is. Still looking around in the bios but I wanted to share my findings. If I figure out how to disable this stupid thing I'll let you guys know. Not sure it CAN be disabled from what I'm looking at.... I'm wondering if the voltage drop to 1.1930 is causing the card to become unstable in high-demanding games with these newer drivers from nvidia.

Alright some new info. Apparently kboost forces a constant 1.2180 voltage.
I tried using kboost to at least stop this voltage drop from happening at 68c but not even kboost stops it from dropping to 1.1930.
Is that intended design?

GPU Boost 2.0 is built into the BIOS. Can't overpower it with brute force. Only way is to use a custom BIOS (but overcoming TDP restrictions requires additional hardware modification if you want to go very far with it).  TDP design limits, core temperature, load (high load will try to boost as much as possible as long as the other three factors aren't exceeded / low load will not boost much or maybe not even go all the way to base clock), and reliability limits (operating within known stable limits for extended periods of time -- stable core speed without excessive temperature or voltage which may degrade the card after hours or years of use) are what cause GPU boost to bounce around between base clock and max boost. Throttling doesn't occur until max temp is reached (if there were another line to the right in the graph above, that would show throttling kicking it down below base clock as temp continued to increase).

So I had a little bit of time to play around, not nearly as much as I would like, but I have come up with some results for anyone interested.
I found a few problems may have been encountered due to using EVGA Precision X and Kboost. I uninstalled Precision X and started to use Afterburner without Force Voltage. I still encounter high TDP usage in games (Witcher 3, GTA V, ARMA 3), but most of the time they can stay under 110% (with said limit set in Afterburner) through gaming - though they get close and may tap the limit at times. Temps still remain under 70 with a decent fan profile.
With these changes I have been able to reduce the amount of throttling (yes throttling - it's the word I'm using as it describes the problem well and everyone knows what I'm talking about), albeit not completely gone. In case you didn't read before I was getting throttling under advertised min speeds at times.
I'm still not completely satisfied that I can't keep a good constant speed on my card at ALL times, but things have improved, and gaming performance shows consistency as well. Please note I NEEDED to increase power limit in Afterburner 110% to keep from large amounts of throttling in games here. I'll continue to work on the problem and report back for anyone following when I get some more time.

rez this old thread. I am using a GTX 980ti Hyrbid. Running my CPU on XMP at 4.4ghz and ram at like 3600. Ive been trying to overclock my gpu past 1400mhz , but I get some blackscreens depending on game , my card is sitting at 60c and I cannot get it over this temp how hard I try. power and temp target set at max. the most I am getting is an 80-90 mhz oc. Just wondering why I cant get more if I have the headroom? like some said I may have to change the bios? or at this point just wait till I upgrade my res to 4k and buy a new card.. just seems like this beast is just waiting to come out of the box but I am restricted by something.

Sounds like you are restricted by the silcon lottery. There's not much you can do if the chip doesn't want to cope with a higher frequency.

@Kyle1827 +1 to this. You can check your cards ASIC % quality with GPUz , My weakest 980 Ti has 72% ASIC Rating, and It really doesn't like overclocking past 1450Mhz. Where people with higher ASIC ratings might not have any issues reaching 1500+Mhz.

ty_ger07 said it. I believe your card is listed for 1228 boost clock. Anything past that is *technically* a bonus, and once you start crashing the chip is generally tapped out.
The issue I was having in this thread was related to temps, software, and my general dislike for the new clock throttling technology, but I've since come to learn to live with it.

I just did this for the fun of it, for my Titan X 12gb, and I get an asic of 64.7%, 88% LOWER than what they have validated in their database. And, I dont oc. No wonder it cant run just games properly with no oc, hehe. :P Is there any other cool little things like this to see if my card is good? Or just cool little things to know? Maybe something that might indicate that it is getting worse (besides actual gameplay and temps?). I am new to all of this monitoring of video cards, and gpu'z. Thanks.

well I just ordered a 1080 hybrid , see if I can get better lottery chances.. it was at a good discount $590 currently. Not much of an upgrade but I also needed to change my motherboard. I also just downloaded GPU z to find this ASIC value but I was unable , I also was wondering it says PCI express 3.0 x16 , running @ 8x , which is odd cause I have my card in the 16x slot? or is this some kinda bug , Ill have to check , be switching the stuff anyways in a few days.

It depends on what you are doing when you are looking at gpu-z. If you are just sitting at desktop doing nothing, it can throttle itself to pci-e 2.0 and x8, and when you start gaming or are doing a stress test, then it should go to pci-e 3.1.1 x16.
If its staying at x8, then you need to change the pcie setting in the bios to the correct setting.
If you have an m.2 card, then you really need to read your motherboard manual to see what to set everything at to get x16 speeds.
