    im gonna do that if/when @ vapochill


    well guys heres the guide to 1.36vcore (1.39375 max)

    i bridged 1/2/3/4/11/12 according to the diodes (d19/d15/d14) on the front of the card

    step #1
    - simple way to increase vcore from 1.15v reference

    1.26vcore @ load

    step #2
    - the lower the resistance at this resistor the higher the vcore allowed
    - pencil this resistor to bring resistance down to around 350ohm

    1.29-1.33vcore @ load

    step #3
    - this point increases vcore according to the resistor in above pic ^
    - solder a 150ohm resistor to ground from this red point

    1.36vcore @ load

    2.20vmem @ load

    unfortuanately no matter how low the resistance gets @ step #2

    all is limited to the reference voltage: 1.39375

    past this voltage further mods are needed

    im sure this still confuses some so if you guys want to revise the mods feel free
