    I was wondering what people who have either the 8600M GT and 9600M GT in their MacBook Pros can overclock their GPU to in Windows without instability in games. People with MacBooks and the 9400M can post too if they overclock. Here's what I usually have mine set at.

    8600M GT:
    Core: 560MHz
    Memory: 800 MHz
    Shaders: 1200MHz

    The Macbook Pro gets so hot at normal clock speeds as it is. I wonder how hot it gets at over-clocked speeds. :eek:

    Actually you can even overclock the CPU and memory via NTune on Windows.

    Yeah, it does get hot, but I have my fans at 8000rpm and have it on a cooling base. Plus Apple ships the MacBook Pros with graphics cards that areUNDERCLOCKED by about 100MHz!

    Surprisingly, the hottest I've seen my GPU is under OSX playing WoW where the GPU isn't overclocked. It's gotten up to 94°C.

    I need a bit of help here. I've got a late 2008 2.4 MBP and I wanna "overclock" my 9600m GT to its normal settings. I'm on WinXP SP3 and I've got nTune and RivaTuner installed now.

    Now how do I go about pushing the clocks up to normal? I just don't want an underclocked card. I'm only using the Windows partition for games so a bit of a performance boost would be nice.

    Oh and I'm using the Dox Custom 185.68 drivers from LTV2G.

    if you don't block the vents, and for gaming you usually keep it on a desk or something... i dont see a reason for overheating on the newer MBP's

    my girlfriend has a Penryn and that hasn't had any problems either

    Well, I definitely overheat my MBP when I play Dawn of War 2. High RPM, good ventilation.

    Why would overclocking help?

    Never mind, just saw the flow in my reasoning.

    That's a good tip. Avoid putting the notebook on anything but a hard surface. The slightest softness can raise temperatures a great deal

    I did some clock speed measuring on Unibody MBP after hearing that it was underclocked by default. I think that assumption is inaccurate for the 9600m gt. Clock speeds were getting up to 500/800/1250 - standard for the card. The lower speeds you see in the control panel are for a semi-low power state.

    Let me know if I'm wrong but I'm pretty sure about this.

    Yeah I also read that the clock speeds increase once the card is actually used.

    Stands or elevators help MacBooks breath quite a bit. Not too helpful if you don't use an external keyboard/mouse, and is even better when you have an external display as well.

    Did you measure it under Windows or OS X?

    Just go into the Nvidia control panel and change the clocks under the performance options.
