    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?

    i overclock a dell d630 by removing its leg and without speedstep cpu lock the multiplier to 6x and when i solder the pin 45 to ground cpu fsb return to 200 and disable the overclock there is any way to keep multiplier in it's full 12x

    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:
    [​IMG]

    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.

    anyone can help me i put different resistor between pin45 and ground i try 10k 5.6k and 100 ohm resistor and try to overvolt by vid mod but multiplier stuck at 6x does if i change its t7500 cpu with an amd cpu multiplier will back to normal state

    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.

    what is a pot,i thing if i use a bsel mod to underclock cpu it would work does there is a mod to downclock a socket p or overvolt cpu when eist is stoped

    i bsel mod this cpu for 333mhz bus speed but computer dont turn on with mod i think this is for memory limit does i can change memory timing and dram frequency for bsel mod to 333mhz by cpu or pll moding

    Did you try 333Mhz with a 6x multiplier? 333Mhz fsb with the stock normal multiplier is too high for that CPU. You also might need to slightly overvolt the northbridge.

    Hi,

    Another overclocked laptop, the Dell Precision M6400.

    I just put a little wire one the socket to put BSEL2 to VCC. Fsb Goes from 266 to 333 Mhz and the P8700 goes from 2,53Ghz to 3,3Ghz.
    It is a jump of 20% in performance.

    The INTEL Chipset does not see the BSEL MOD and don't lock the processor multiplier to 6x....I'm Lucky.

    Will try next week end with my other M6400 with QX9300. If it works, It could be a 3,3Ghz QX9300 laptop, quite good.

    The QX9300 already has an unlocked multiplier. There is no reason to try to overclock it via the FSB. You can determine the optimal multiplier and voltage using throttlestop. Then you can pin mod the multiplier and voltage to get it to work just how you want it to.

    Yes I know but what a overall performance jump when you boost the FSB!

    Here is the proof with the QX9300 @4Ghz:

    Good work on your overclock.
