    OK guys, I'm new here and thought this would be a great first post.

    So for a while now I've been using a Compaq presario C700 notebook as my main computer. I got it for christmass back in '08 so its kinda puttin' on the years. anywho here are the specs.

    -(upgraded to) windows 7 pro
    -1gb ram
    -(upgraded to) a 128 gb ssd :D
    -Intel GMA X3100
    -1.7Ghz Intel Celeron

    as you can see the setup is not ideal. What I really want to do is overclock the processor. I've tried setfsb and clockgent, but no dice :( Also, I know what PLL I have it is a slg8sp512t setfsb has one generator that it REALLY close, it displays the correct bus speeds but the slider just jumps back when I try to move it. I dont want a crazy overclock, if possible I'd like to push it to 2Ghz. If anybody knows how I can manually tweak setfsb to work that would be awsome :)

    OK here goes,

    probably should have added this before, :p but I already had that datasheet

    Well if you ask me, TME mode is probably bit 6 of byte 9. In the datasheet you can see that bit is reserved and read-only (which is common for the TME bit). Since the bit = 1, overclocking is disabled. you would have to do something similar to what I did here:
    http://forum.notebookreview.com/har...pll-pinmod-overclocking-methods-examples.html

    TME often shares the PCI2 pin.

    So I think your only chance to overclock is to try to disconnect pin4 and reconnect it to GND (using a resistor). Then setfsb might work.

    ya your right, I just checked bit 6 of byte 9 and it is a 1 :mad: so by grounding the resistor that is connected to the TME pin the *should* disable the protection and allow me to use setfsb, correct? In your picture it looks like there was a gnd right next to the resistor, is that common to have? and what way do you recommend to go about soldering these tiny components? :confused:

    Yes I think so, unless your PLL doesn't have the overclocking function (making the M/N programing registers just dummy registers).

    Not too common, but I wish it was :D

    Very small tip on your iron, Use a magnifying glass and take your time.
    It's a good idea to practise on some old rubbish motherboard before you attack your laptop.
