    The default graphics driver from lenovo over locks it quite well. It does not let me overclock at all. I had to use a third party driver. I really just replaced all the dll's with 169.28's and that worked, it also let me set my refresh rate up to 150, its amazingly smooth.

    Highest overclock: 675/1000

    How did you set up your refresh rate to 150?

    I don't think the monitor can even keep up.

    Sorry, I mean overclock :D

    I replaced my FX 570M driver with 8600GT driver and it works very well for gaming. But, still, when I play COD4 with 100% highest setting, it's kind of slow in the game. I heard some people have overlocked the GPU at 600 (475 original) and memory at 900(750 original) and the video card's tem is stable.
    I am wondering will overclocking improve the video card's performence when gaming? Anybody have any thoughts?

    Don't you guys get scared overclocking a GPU that is soldered to the board and is not replaceable? I would think of maybe doing it with a desktop card that I could replace if it burned out.

    I set the fan to 4500 rpm and it cools it quite nicely.

    overclocking gave me 25% fps increasing with 40% clock speed increase

    To change the refresh rate I would usually use powerstrip however since this is a 8 series gpu then it doesn't work; i have to resort to nvidia's buggy control panel. It doesn't add resolutions when I do it and only saves when it feels like it, but luckily I found a repeatable procedure to get it to save. Some one else also pmed me about this

    The LCD can keep up just fine. The real question is can the individual liquid "crystals" twist fast enough. At 150 hz, Many gray to gray transitions work well within said frequency, but if it is too slow it will cause a blurring or ghost effect. I believe though the response times are sufficient for 100hz.

    Generally though if you are not comfortable overclocking you shouldn't, Overclocking voids your warranty :eek:

    That's why there's a nifty util that controls the fans so it won't burn out. ;) OC'ing without it is asking for trouble imo.
