    Hey all,

    Trying my hand at overclocking for the first time (rig in my sig), and rivatuner is giving me a load of BS. I followed the instructions from the sticky, but it's telling me my stock clocks are at 383core/767shaders/301memory and that is definitely wrong. The highest it'll let me take them to is 575/1150/455 which is lower, except the core, than the stock settings.

    Ive got GPU-Z up and it's telling me my gpus are running at 500 core/799memory/1250shaders.

    Any idea what's up with this?

    Why don't you use Nvidia System Tools? It's guaranteed to work.

    Rivatuner is designed for desktop chips, therefore it doesn't read some of the mobile cards right. The dev has no intention for adding mobile support. If the GPU-Z clocks are correct then you are fine.

    RivaTuner is not a good OC'ing program for notebooks.

    the best way for mobile Nvidia cards to OC is by:
    - using Nvidia System Tools (formerly Ntune)

    Or (the most common way here on NBR)
    - dump the VBIOS (with GPU-Z), edit it (Nibitor), and re-flash the VBIOS.

    then run some benchmarks (while monitoring the temps) to make sure to stable and has safe temps.

    I'll try the first way, I'm not really comfortable messing with the VBIOS right now...off to dl nvidia system tools.

    Even I did the VBIOS for my old videocard.

    its too simple to not try, especially since it makes the videocard OC permanent (until you flash it again)... instead of dealing with software OC.

    And you can make your videocard cooler if you undervolt it... which does NOT affect the performance. ;)

    Just overclocked to 600/900/1550 shaders

    scored P12079/G10061

    I think I'll stop here, everything ran nice and nothing seemed to get hot.

    Edit: Ran Vantage again and got a similar score, but also ran Hardware Monitor and got these max temps:

    core # 0 (hottest) 67C
    Core # 2,3,4 were from 59-62C
    HDD 48C
    9800m GTX #1: 84C
    9800m GTX #2: 67C

    I believe the danger area is 90C so I should be fine there, but I'm worried about the 2 GPUs having such drastically different temps, is that normal in SLI?
    Other than that, everything else looks fine.

    I dont think that te defference in the temps is to dangerous but I am not to sure because in me laptop there is only one GPU and the max temp that it reaches when it is overclocked is 80-85c.
