    hi
    I notice that acer 9300M GS is slightly factory overclocked :)
    anyway,
    anyone tried GPU overclocking?
    I tried OC my 9300M GS from 580Mhz to 640Mhz
    Runs v.stable. Should go up OC somemore?

    PS: acer laptops are known to have bad cooling systems

    Regards

    Dude, you're in the Acer forum, everyone here has tried (and often succeeded) at overclocking their laptops. And Acers are no better or worse as a brand for cooling than anyone else. Asus, Lenovo, Sony, Toshiba, and so on, they've all made plenty of models that didn't cool well and thermally throttled. Right now the Lenovo X220 is known to thermally throttle terribly, as are many other models. Some Acers are better cooled than others. The 3820TG had a fantastic cooling system that kept a core i5 CPU and ATI 6550 GPU in the 70C to 75C range for most folks, which is actually well below their max operating temps of 105C and 85C respectively.

    So, since your sig doesn't mention your machines, what do you have with a 9300M GS in it? And what kind of benchmark scores can you get out of it with overclocking? Basically you can overclock til you start to get artifacting, then turn it down a bit. I use MSI Afterburner to OC my 5650 ATI GPU and get stable performance at 650/900 no problem.

    Yeah, I can oc my memory to 950 or 975 before it has issues, but the core starts flaking out when I hit 670 or so. Make sure whatever you settle on you test it hard, paying attention to GPU temps etc while gaming hard. Sometimes what seems stable gets unstable after an hour or so of playing.

    So 670Mhz is too high? What the reconmended stable and cool Mhz?
    EDIT: I also wanted to buy a new GPU (the 9300M GS is a very lousy GPU)
    So, the 9300M GS is a MXM I card, does MXM I card works with MXM II cards?
    The pciture of my card

    Look up the Acer MXM thread on this board, it has all that info in it. I run a 4820TG, so switching graphics is not doable for me. For you, the max frequency is whatever it is for that individual card in your machine. Each combo is a little different.
