    Hey there! I'm a long time reader and first time poster here. Hoping I can get some help because most of the useful links and pictures I've found here and elsewhere are dead.

    I've found my PLL which actually ends with a k and not an F...

    I've read two success methods to pin mod. One was to simply snip pin 11 and the other to solder a 10k resistor from it to ground.

    Question - what ground would I solder to? A ground pin on the PLL or something else?

    What do I do after That? I've been reading every related forum and googled this subject but I need more info.

    Can anyone summarize in a step by step list how to do this, recommended tools, whether soldering a resistor or simply cutting the pin WorkS?

    Also, does anyone have any info or instructions for voltage modding? We need a solid thread for over clocking methods and motherboard tweaks.

    usually what pll mod does is it unlocks frequency modulator, so you can change front bus frequency and therefore overclock all devices that use that frequency to run including CPU. Once the pll chip is unlocked , usually you would use some software, or even modified BIOS, to reprogram the base frequency.
    Ground is common for all devices inside computer, so usually it doesn't matter at what point you connect to the ground. There are many threats here about overclocking and voltage modding, but since each computer could be little different, you just need to search for proper topic, for example if you have haswell CPU, you could download Intel's XTU program to adjust voltages and do limited overclocking without any mods whatsoever.

    [​IMG] Also, does anyone know if there are other pin mods on that PLL

    Well I tried soldering a resistor to a metal ground post that was being used by the modem I removed and now it won't boot. Also I accidentally touched the PLL chip with my soldering iron. Am I screwed??

    Can not see the image but if you shorted the PLL you very well could be. Being as you mentioned in the cross post, BTW that is a no-no, you should have never attempted this if you do not have a good Multi-Meter. Also always keep a good solder scraping tool around.
