    I dont' have any info or experience when it comes to overclocking. I am interested in knowing how I would overclock my Dothan and/or my MR 9700 graphics card.

    Would like to know how far they can be overclocked without melting the components down, how to do it etc

    thanx

    The Pentium Ms are essentially unoverclockable by design. Because of how they were designed, any attempt in overclocking will be near nill. For the vid card, well I hope you've got addequate cooling. The only issue in my eyes is proper cooling so you don't overheat and destroy it. Laptops aren't really designed to work much beyond the heat disipation levels they're at now. I'd be weary overclocking anything in a laptop just from the heat perspective.

    thanx for the input.

    the reason I considered is because I heard Pentium Ms run very cool (mine runs at 51C, fan doesnt kick on until 66, OS doesn' take over until 93)

    Yep, they run cool cause they're running at such a low power. However, this doesn't mean you have a good amount of heat overhead for overclocking. Intel designed the Pentium M chip a little differently. They eseentially toned down the archetecture to match the slowest part of the chip. So, unlike a normal P4 where overclocking will make the cpu gain through certain archetecture areas with room to operate faster, the Pentuim M is essentially already running at full capability in all aspects of its design structure. This allows the chip to run suprisingly efficient and still perform very well. However, this means you can't overclock the processor hardly over what it is by default.

    I've actually heard of overclocking pentium M's to 2.4 ghz. They are extremely cool and efficient, they are perfect for overclocking. The radeon 9700 can be easily overclocked using Radlinker, a utility that comes with the omega drivers at www.omegadrivers.net

    Yes, I saw a report on overclocking a Pentium M too, but the laptop was no longer "portable" - there were all kinds of extra fixtures for an oversized heatsink, massive cooling, etc.

    But that extreme cooling raised the clock rate 25%, surely a stock cooler could OC 10%.

    Bonjour,
    Merci pour le lien monsieur. Great link if only my french was better at least it has pictures. Has anyone heard of a speedstep hack to overclock a PentiumM? Does speedstep reduce the mulitipler or the fsb? No luck with google on the subject. I would love to overclock my 1.5, when I get it.
    Au revoir

    On Tom's Hardware they say "Speedstep Controller adjusts the voltage regulator and changes the CPU multiplier".

    <http://www.tomshardware.com/cpu/20001107/mobilecpu-05.html>

    So, I guess the speedstep controller detects what processor is in stalled. It still would be nice if there was a way to fool the controller.
