    Question help me for mod vcore asus k8n-e

    hello everybody, I would like to know if somebody know the exact
    operation of the component "adp3166" (on the k8n-e) and how I could
    make to make him leave more 1.55V.

    Otherwise is this somebody could help me to make a modification of the
    vcore on the motherbord asus k8n-e?

    Thank you in advance.

    (sorry for my english, I'm french)

    Welcome to the forum!

    Pin 8 on the adp3166 is the feedback pin, so the Vcore mod should be to connect a variable resistor between pin 8 and ground. A 20k Variable resistor should be ok, but if you want conformation of the value, can you get a resistance reading between pin 8 and ground, and pin 8 and a Vcore read point.

    If the variable resistor between feedback and ground doesn't work, then you will probably have to cut the feedback trace and connect a variable resistor between the points.

    sorry but I don't understand what is "feedback trace" because my english is very bad.

    The feeback trace is the connection on the motherboard which connects the feedback pin (pin 8 on the adp3166) on the voltage regulator to the regulated voltage so that the regulator knows how much voltage to give out. Usually there is a resistor between the feedback pin which allows you to just connect a variable resistor between the feedback pin and ground to mod the Vcore supply. If there isn't a resistor between feedback and the regulated voltage then you need to cut the feedback trace and put a variable resistor beteen the regulated voltage and the feedback pin.
    If you do a cut-trace mod then you need to set the variable resistor to its minimum resistance (0 ohms) and raise the resistance for more voltage.

    Hello,

    Do you have any information about the vroop?
    Connect the pin 17 and 18 with resistance, not work. My vdroop decrease.

    I'm not sure about this, but try connecting a varable resistor between pin 17 and ground for the droop mod.

    hello,

    with vcore at 1.85V my 3400+ jump to 2776Mhz but i don't +.
    The vdroop not fonctannaly.

    Connecting pins 17 and 18 via a variable resistor should reduce the droop. How low did you decrease the resistance?

    i don't understand , what is "low"?

    with this method of pin 17 and 18, it will be better?

    with this last sentence:


    pin 17 = 2.0V
    pin 18 = 1.9V
    with a resistance of 10k on the pin 17 to the ground, the voltage of the pin 18 jump to 2.3V. is it good or not?

    Did you try conencting a varaible resistor between pins 17 and 18? You will probably need to set the variable resistor to about 28k for the droop mod to be the most effective.

    hello, not I do not have to test yet between pine 17 and 18 I have
    just to test on pine 17 with a resistance of 10k. I will test
    continuation between the pine 17 and 18 and I you tien with the
    current .
    thank you

    I don't have the k8n-e. I've only got socket A boards here

    hello persivore, the vdroop is good with a resistance between pin 17 and 18 but there is no improvement of the frequency of my processor. it would still have a modification has
    to make?
    wath''s your job?
