    is that a good enough image to tell?

    RTM875T-606 datasheet & application note - Datasheet Archive

    http://forum.notebookreview.com/har...clocking-methods-examples-23.html#post5457881

    is there enough information here to tell if it's locked? if it is locked is there enough info to figure which pin needs to jumped to ground?

    Toshiba L305-S5917

    Hi, can someone help me to overclock my Lenovo T61 (Widescreen)

    Here is the overclocking method im trying to follow (page 121) : http://forum.notebookreview.com/har...pinmod-overclocking-methods-examples-121.html

    This is what have done at the back side of the pcb:

    The layout of the front side of the PCB is a little bit different than the layout in the pictures in the guide, i suspect this is because he had 4:3 screen and i have a wide screen. What should i connect?

    the square and widescreen models use a slightly different layout. one person here have said that they confirmed to overclock with the widescreen model.

    Hi
    I have overclocked my Lenovo T61 laptop, by changing the fsb from 200 to 266. My Lenovo uses the intel GMA965 (X3100) Onboard graphics, so increasing the FSB has also overclocked it. Now I have run into a problem, where if I install the graphic drivers, I will get black screen as soon as I boot into windows. Can I fix this?
    Can I can overvolt the onboard graphics?
    Can I underclock the onboard graphics?

    It might be a better idea to use a POT, so can you change the resistance at any time if you need to.
