    How can I overclock my 6870? I've overclocked before on desktops but am curious as to how I could do so on my laptop. What programs do yall use? I see no one on this forum even talk about 6870's :(

    Trixx is ok, but it gave me a lot of issues. I then came across a post here that involved altering the clocks at a bios level and changing the registry. It's been smooth sailing since. Thing is, I have lost that post. I will try to help you find it if you are unsatisfied with Trixx.

    well, with trixx I am experiencing screen flixering when I overclock, what speeds are yall clocking to? and are you altering the voltage?

    you can't alter the voltage on these cards with Trixx. Sorry dude, i'd help you out, but i have a 6990. For everyday, my 6990 is running 800/1100 for gaming and stock for everything else. For benching, i can go as high as 837/1250

    Differant cards clock differantly. Only real way to find the best clocks is trial and error.

    So currently I am using trixx with my core clock at 800, memory clock at 5000, and gpu voltage at 1125(some said I can't alter it, but it is letting me change the value?)

    This is about the highest I can get it whilst not Gray screening.

    I do see a bit of framerate jump but I was wondering why my screens during loading and even out of game are flashing white lines.

    you can bump your voltage?

    if you're getting white lines, back off a little on the overclock

    It is letting me change the voltages in trixx application, yes. Should I modify it any?

    also overclocking AT ALL produces white lines, the same amount it seems, untill I overclock enough to gray screen, which is somewhere around max what trixx will let me.

    i wouldn't touch the voltage unless you are 100% sure it isn't going to cause a problem because over volting is the #1 reason why video cards fry. If you're just overclocking on stock voltage, worse that happens is it freezes or blue screens. Then you go back to stock and everything is fine. Within trixx, i'd really set everything back to defaults (click default button). Then move up slowly on the core first. Then memory

    No white lines when you run at stock voltage and clocks? what about stock voltage and just slightly overclocked?

    i have noticed that when i got my m17x r3 that when i overclock the 6870m it shows the white lines at the top of the screen when not an actual game. don't know exactly what the problem is. I'm gonna repaste with arctic silver and order some new thermal pads and see if that fixes my problem or not.

    no i haven't i wonder if its a bad video card. i have a 6970 video card and am going to try putting it in and see what happens. the only thing i can think of is a bad graphics card. if its not the video card that leaves the screen or the motherboard but it wouldn't make sense since it does it only during overclocking.

    i just got through installing a 6970m and it seemed to help the problem. the only time i notice any flicker is right after i change a clock speed and its only for a split second.

    Yup I've noticed the flicker too, it's a driver issue. Also clocks don't come down either (to 100/150 like they should when idle), again a driver issue. To combat that I've just flashed a custom vbios with the clocks in my sig.
