    It's weird you said it WORKS on your GTX670? Then wondering why it wont work on my GTX 660 TI. Definitely goes from 1228 to 1215 when it reaches 70C.

    I did what you said and also rebooted.

    but go below 1215 ? if not..its fine... seems just keeppler boost disabled... see if the speed go down after 75 C oor more.. like 1100mhz or below... ( u need to apply powermizer each time windows boot )

    ps; ALSO , if TDP go UP to max value.. the clock will decrease a little bit.. seems to be this.. try increase POWER to 120% or 125%

    also.. do the test with GPU-zZ RENDER TEST.. like i did

    dont work, what I did was scale back my oc from winter 1280/7200 completely stable 1.21v to 1241/7114 1.175 volts

    Well I don't see it as a "problem" in that sense, I just wanted to know whether there is a way to stop the "throttling". Personally I dont care whether its 1228 or 1215.

    The ONLY time I would see temps over 74C is with FarCry 3 (when I play many hours), there is also no way on earth I would see anywhere close to to 70C with the test in GPU-Z, this only uses my GPU like 60%

    Why would you have 74C with this test? :)

    As for the rest, as said I tested already with Kombustor/FC etc. and this tool but definitely the temperature throttling still kicks in.

    MAYBE you have a different driver or it's a BIOS thing that it can be disabled with SOME cards and with others not.

    Edit: Ok, cannot be driver since I also use 320.00

    his fan speed was at 25%, I tested in both heaven and valley and I began throttling at 70c ish, like always

    the driver has a profile for kombustor or furmark (i think) ... my gtx670 run at 915mhz in kombustor /furmark...

    dont try this tools cos the driver limits the speed.. u must try in games

    also.. like i said.. i think that your problem is related to POWER LIMIT .. when gpu hit 110% the clock throtle.. try increasing the limit to something like 122%

    im using 320.00 driver...

    lol I am at a 150 power target, it does not work for me on 2 680 ftw+ 4gb.

    Guys I discover Why my GTX670 dont throtle ( oonly a little bit)

    the answer is: I changed the bios so the minimum base clock is 1200MHz so lowers the clock to 1200 no less
    download it to the "KeplerBiosTweaker" (works on 670/680)

    source> http://www.hardwareluxx.de/community/f14/nvidia-geforce-gtx-600-serie-bios-files-932143.html

    and> http://rog.asus.com/forum/showthrea...25-f%FCr-GTX-6xx-Reihe-680-670-660-650-UPDATE



    Important note ..

    download your vbios using GPU-Z.. then open in KeplerBiosTweaker

    change base clock , boost clock and boost limit (all values must be different, if egual can cause errors)

    [​IMG]

    [​IMG]
    adjust this to match "boost limit" that u specified...
    [​IMG]



    :)

    the proof : I test crysis 3 right now and got this>

    [​IMG]

    to flash the Video Card u need NVFLASH ... i use "nvflash_windows_5.118" and this works fine ( flash im windows) ... but its highly recoomended to flash using boot method.. see the 2 urls i posted Above (read the page, translate to english :)
    .
    hope i help you
    .

    you must increase the POWER LIMIT in afterburner to avoid the second Throttle.. based on TDP (power consumption) , like in farcry3 the TDP goes higher than 120%.. if u leave power limit default, the clock will throttle.. set TDP to 122-123% (works fine here)

    All this power boost nonsense is really annoying. I Wish Nvidia would just give you the option of using standard normal OC'ing instead of this junk

    I would like to hear about where the summer averages 70C. Not even in Saudi Arabian deserts has this been the case for decades, or so I believe. ;)

    Just a bit of humor. Carry on!

    Guess I have got lucky with my two Gigabyte GTX 670's because I have never gone over 65c on ether card. But then my GRone case has 8 fans running and has very good air flow so it gets plenty of fresh air coming in.

    yes 70 C is too low.. i think that until 78 C its acceptable.. 70 throttle is really nonsense.. o_O

    It doesn't need those fans at all. My case has a single, slow-running case fan and the card still doesn't exceed 65°C.
    These cards are so easy to cool really, even with very low noise "pollution".

    Just a question guys since i don't own a kepler card when you say that the card throttles at 70c do you mean that the 3d clocks drop down to low power 3d or 2d clocks ex. like 500mhz on the core or just the turbo boost gets disabled and defaults back to stock base clocks of 1006mhz on the gtx680?

    in Msi Afterburner.. increase the POWER LIMIT... dont go more than 130% ok... put 122% for example .. if 120%+ is not avaible, u must mod the bios to increase power limit ( using Kepler Bios Tweaker)

    the throttle go until it oreachs the 3d base clock.. for my GTX 670 the stock base clock is 915 , boost 980 kepler boost 1097 , so the card may throttle until 915...

    Thanks for the info Iruwen so only the boost feature and overclocked cards start to throttle down at 70c according to the graph.
