    Hello.

    I have a few questions for you guys:

    1. Is it possible to underclock my GPU even if the M17X has switchable GPUs?
    2. Can i disable the IntelHD graphics and make the Radeon HD 6870M the default GPU?

    Please help. I tried to use AMD OverDrive and ATI Tools but it only gives me automatic BSoD.

    I don't want to put my GPU to the max because it goes into vertical stripes and goes into BSoD when it reaches a certain heat temperature. I just want to lower it a bit.

    When i am using Maximize Battery Life setting (300Mhz/400Mhz) it never goes into vertical stripes crash, but when i turn it Maximum Performance (675Mhz/1000Mhz), a minute or two.. it goes in display crash > blackscreen > BSoD.

    1. Yes. TriXX serves the purpose well. https://www.sapphireselectclub.com/ssc/TriXX/TriXX.aspx. Switch to the 6870M, go to the Overclocking tab and use the sliders to adjust clocks to the desired levels.

    2. Yes, but for what purpose? Just switch to the 6870M and leave it there.

    The more important thing is that you should never experience overheating with a 6870M at stock clocks. You need to remove the bottom panel (take out the battery and remove 2 screws) and use compressed air to clean the dust out of the fans, vents and radiators. If that does not resolve the issue, then repaste the GPU. Easy process; just follow this illustrated guide: http://forum.notebookreview.com/alienware-m17x/561599-m17x-r3-cpu-gpu-re-pasting-guide-w-pics.html. That guide will also help you open up the bottom panel and remove the fans for cleaning purposes if needed (which is probable).
