    The downclocking only seems to happen when the card is manually overclocked very high, the turbo boost then seems to cause the protection to kick in. So yea it will apppear to be intermitant but i think it can be avoided.

    Running stable now using MSI Afterburner at following settings:

    Stock GPU settings:
    Stock GPU Boost: 1084Mhz

    FanSpeed Auto (Fixed 75% while running 3D)
    PowerTarget 132% (Max)
    CPU +166Mhz (1250Mhz total)

    My FPS while playing multiplayer BF3 on the Metro map using ULTRA settings with AA off was:

    Min:41
    Max:201
    Average:111
    Temp: 66/68c

    Edit: Do you guys see any increase in FPS while overclocking the memory, and if yes bij how much?

    I think my gpu boost is broken, wich might be a good thing, i look at some video on the web and see gpu boost is always changing the clock while runing a test. But on my card example on CPU + 160 the gpu clock goes to 1245. When i load a test or game the gpu clock goes to 1245 and stay there untill i close the test or game, making a straight line. Example on uniengine, between each scene the power usage will change but the clock will remain at 1245 making a straight line. Il try to make a video on this and post on youtube tonight. But i also notice when playing game that are not hard on the gpug like Dota 2 the gpu clock itself lower.

    @Fur4x - The boost depends on how much power you're giving the card and how demanding the game is. If you give it plenty of overhead and the game isn't really demanding (e.g. not 99% GPU usage) then you might well see the core clock running a constant rate. I've seen the same in my games when the boost clocked the core at 1,137 MHz for the duration of play but also I've seen it fluctuate as well, going as high as 1,287 MHz with the +150 MHz core offset, and as low as 1,058 MHz. All the time though the game was running at or as near to 60 fps as possible with v-sync. I think what you're seeing is normal.

    Yes but it depends on the game as some benefit more than others.

    Increasing the memory clock obviously has the effect of increasing the memory bandwidth available so you can push higher resolutions and/or levels of AA. I don't think the framerate increase is as noticeable from just increasing the memory clock as the core clock on its own from personal experience but together overclocking the core and memory can significantly boost the framerate as seen in Guru3D's GTX 680 overclocking feature here: http://www.guru3d.com/article/geforce-gtx-680-overclock-guide/

    The powerlimit is not the only thing that determines the max gpu boost.
    Also the cooling play a role. I tested this using stock settings with powerlimit on max and auto cooling. My GPU boosted to max 1084Mhz.

    When i turned up the cooling fan to 100% it reached 1091Mhz when boosted ;).

    I've been taking mine slow. Right now I'm at:
    Power Target: 132%
    Gpu Clock Offset: +125mhz
    Mem Clock Offset: +100mhz


    Played about 5 hours of ME2 @ 1920x1080 2xSGSSAA and FXAA with no issues. I'm sure the game doesn't push the card too hard even at these settings but it looks nice and plays smooth with no problems so can't complain.

    Thanks for results.
    Just for compare although you are on 1920x1200.

    Gonna be interesting to see what this card can do under highend water and with voltage unlocked.

    My DCII 580 GTX clocks from 782 core to 1 ghz stable with 1.215 volts ( bios modded).

    ~27% OC wich is quite decent.

    680 gtx

    With a standard clock of 1006 would result in around ~1280 mhz if we assume they generally OC atleast 27%.

    Question is if they will be able to go beyond that, since they don't seem to be limited by heat even on air from what I heard when people reporting temps.

    Good thing is though that a 10% OC on the new 680 seem to translate in around 10% increase in fps so thats nice scaling.

    @Sneakers - My GTX 680 can go to 1,287 MHz on the GPU clock on the reference cooler using a custom fan profile and temperatures are in the low-to-mid-70s C at most and generally under 70 C for the majority of the games I've tested (around 40 or so).

    I'd imagine that a GTX 680 with a 6+8-pin PCI-E connector like the Palit Jetstream will allow you to push it much higher than that on air and even more if you use water cooling.

    let's hope someone find a way to use 1212mV with softmod on these cards otherwise it's not easy to maintain 1400s @1175mV.. then i may consider to buy one..

    The card does produce 1.21v in 3d already,but you must use a dmm to see it.
    Man some of you guys have cards running over +200 on the cores?
    Even for just 3d11 1 only does +140 which is 1150/1200
    its deflault boot vid is higher then other card .02v also .
    Card 2 will go +187 1190/1246 default voltage
    which is same max 3d volts as the other one 1.21v

    Strange today in testing the h70 modded card needed for 3d11 repetable runs x2
    1.23v =+162 1170/1224
    1.26v =+187 1193/1246
    1.30v =+209 1215/1268

    My card can do 1250mhz stable on the core wich is about a 24% oC. Is it a good card or is it average ?

    Same with mine, 1250mhz for 24/7 and 1330mhz for 3D mark 11. Thats with the 1.175v limit. 1.2v would really open her up a bit more. All on stock cooling.

    you got a nice card, mine wont go over 1265mhz, the card or nvidia driver stop responging, and it require GPU + 165 to get 1250mhz

    That is strange. Mine only needs +140 from MSI afterburner for 1250mhz...

    at +140 does it give 1250mhz on a straight line or is the gpu mhz fluctuating ?

    I will tell why it fluctuates (assuming you have the Power target set to 132%):

    [​IMG]

    This basically tells you that as soon as it hits 70C it drops the GPU frequency. If you want it to stick to 1250mhz constant, you need to keep the GPU temperature below 70C. For me, it didint fluctuate because i set the FAN speed on MAX and it never went above 55C (for benching). Otherwise for gaming i have my fan on a CURVE from MSI afterburner and it goes up to 70C and it drops below 1250mhz. Make sure you guys remember these temperatures if you are going to be posting bench results... ;)
