    it wont make any deference i think those pads are connected together.
    you wont gain more oc it will probably drain more current but wont make a big deal

    Tomasz25 use one 50k it will be more precise

    According to the datasheet, here

    http://www.onsemi.com/pub_link/Colla...NCP5392Q-D.PDF

    pin#17(VFB) is the appropriate pin. Measure resistance between pin#17 and GND (completely withot power to the card!). Would be best to find alternative soldering spots first. Soldering to those tiny contacts is bad, if there are better soldering spots.

    The mod for this card was already found and attempted back on pages 57, 58 and 59 by ceemic and dragubogdan. Here: ceemic's mod
    However, dragubogdan didn't get it to work. Maybe a second attempt will make it work?

    Hi guys!
    That is right , I didn't get it to work using 100k vr connected to FB pin,but using a 50k vr is working fine.I recommend you to get last bios update from gigabyte.com for better temperature of the card.Regarding pencil mod I still don't know what resistor must pencil.
