    I wanted to overclock my m9750 a little, and it came with 2.33GHz from the factory. Is this pre-overclocked or anything? And what would be a good overclock speed? I have it at 2.4, but I've seen some push the 2.0 to 2.25, so could I push my 2.3 to 2.55 safely? I'm watching the temp, and bumping it up to 2.4 didn't add any heat. (rides right at 153F core temp) these things get so hot!

    Thanks!!!

    You probably have the T7600 CPU which is clocked at 2.33GHz. As for overclocking, Alienware did sell the T7600G processors in their m5790 laptops and had them overclocked to around 2.66GHz. Not sure how the T7600 would do though. However; the m9750 does have a better cooling design compared to the m5790.

    you can Overclock your CPU using clockgen to 2.45 ghz Safely, but if you want more to OC, thats unavailable because of RAM holding back the system , anyway you wont notice anything if you are going to OC for the games, the change will be in max FPS only.

    Cool, thanks! I just was hoping to slightly improve rendering time of video/audio/image production. I know it won't be any sizable increase in speed, but I'm pretty impatient, and hey, every second counts! (I am assuming speeding up the CPU does help with this)

    Thanks!

    Dude don't overclock the M9750. While it may sound cool, it really does put a lot of stress on the notebook because you are overclocking everything, not just the CPU. While it will yield better benchmarks and whatnot, I would strongly recommend against it just because there is always that possibility of something happening.

    I would suggest undervolting though to see if you can get any more battery life.

    Yeah, it does make me nervous to OC the thing (being that I could not ever afford to buy one, I got fortunate and won mine! =D) so I don't allow ClockGen to keep the OC settings at startup.
    Now with undervolting, (forgive my humble questions) this is different than under clocking, correct?
    What would be the difference between the two? Underclocking perhaps useless except to lower temp?
    And is there a ClockGen equivelent for underVolting?
    Because a battery gain when using my (XP) 9750 for non-intense purposes would Definitely be a plus! (always jealous of my friends 13" dell that gets 5+ hours on the road!)
    Thanks!

    undervolting simply decreases the voltage to the CPU by a slight amount, without decreasing the clock-speed or performance. This allows the CPU to run cooler, and may increase your battery-life some.

    @Austin - You MAY be able to get 2h30 minutes of battery life out of your M9750 if done properly. Steps I would do...

    1. Remove your secondary video card
    2. Undervolt your processor as much as possible
    3. Underclock your processor as much as possible
    4. Disable all programs at startup except for the nvidia driver
    5. Hope you have more battery :)

    Do all m9750's have the dual vid card setup?
    I never knew I had two installed, but two show up in the device manager!
    sweet.
    Will removing the card void the warranty (as if overclocking haden't already)
    And do video cards play much of a role in non-gaming video rendering?

    In device manager would selecting "do not use this device" work as well as completely removing it?

    I Believe so. it will give you a handful of battery life ^^

    @Austin - I do not know. It may still just idle at 100% which would always take up power. You can test it out though and see if it works.

    Also, video cards have NO PURPOSE in editing. You may see a difference between a X3100 and a 8400GS, but otherwise no which is why apple sells 2600HD's with their 8-core G5's. So SLi does nothing for your photoshop / rendering work.
