    I have a 9800M GTS and messing around with settings, but it got me
    wondering changing which of the 3 settings (Core/Shader/Mem) has the biggest impact temperature-wise?

    the core is the main part for heat and performance.

    you will quickly realize that the GPU core (shaders is part of it) is the only part with a temp sensor.

    so even if you OC the memory, you will not be able to monitor any of its temp.... which should make you cautious in checking for artifacts after each incremental OC

    Also, speeding up the memory is going to increase more heat; since your mem shares the heatsink with your core, it is also going to increase the overall gpu heat. 90% of games and apps won't perform any better with increased mem speeds. In my experience, you'll just want to leave the gpu mem alone, as its usually the first to die from an OC. The fraction of a performance increase is not worth screwing your card up.

    For now I've under...yes underclocked the core of my 9800m GTS by a mere 25Mhz because I also undervolted it from 1.11v to 0.9v to get my system to run more stable (and most important cooler). Right now under FurMark I'm reaching the max temperature of 66 degrees celcius. Under 3DMark2006 I still get a score around 9300 points (with 182.05 Doxx Forceware Driver).

    Heh, guess I'm doing the complete opposite of you emike09 :)

    Well I will admit you are the first person I've ever known to operate their GPU with the Extra clocks underclocked and voltage undervolted. If cooling is a big deal to you, then you'll want to put down your own thermal grease (I recommend OCZ Freeze over Arctic Silver). 66C is well within the operating temperature. Overclock with clean fans and a perfect application of OCZ grease, I max at 73C.

    Also, underclocking and undervolting is not going to increase stability. Generally, one would want to increase voltage to increase stability {to a point). If you want stability, leave the card stock, running as nVidia designed it to, and use laptop drivers instead of modded desktop drivers. I'll be honest, what your doing makes no logical sense, unless you want to save a couple watts of power when plugged in...

    Someone has to be the first right ;)

    The reason I'm doing this is because of the noise the fan of the M860tu produces. I expected noise when I bought it, but it turns out I'm really sensitive to this (more than I expected). I also could have bought another laptop with a slower GPU, but hey, I still like to play WoW with max settings. Luckely WoW doesn't demand everything from the GPU, so I decided to undervolt it. And you're right about the stability, as I've had a few lock-ups now, so thats why I decided the underclock my GPU just enough to get it stable again.

    Yesterday I re-flashed the GPU with the stock Bios again (just to test) and it seems that around 70 degrees the higher fan-speed kicks in to cool the system down. And that's the stage (and higher ones) that I find too loud.
    I've also re-applied thermal paste (I went for AS5).

    And yes my CPU also got the AS5 treatment and also has been Undervolted.

    But you have a really impressive temperature vs performance ratio!

    Ah, you are using the M860tu. You should put your system in your sig so we know what we are dealing with. I'm always assuming people are using the M570TU / D901C. Ya, the M860tu has to pump a lot of air to keep components cool. Have you considered a notebook cooler? Drops my temps about 2-3C.

    Hi there everyone.
    I want to buy a Alienware M17. I will mainly be using it to play games that are fairly graphic intensive. Aswell as a bit of video editing. But I am unsure about what spec will give me the best performance for my budget....
    My budget is around £1500. So, I'm asking you what way I should customise the M17 in order to get the best possible performance out of my budget.

    Um, why the heck are you asking here?

    Try posting your question in the Alienware forums:
    http://forum.notebookreview.com/forumdisplay.php?f=1018

    If you want my recommendation, don't waste money on an overpriced, low quality alienware. Its nothing but a name.
