    Hi all,

    I'd just like to know if any of you have successfully done a pencil volt mod on an X800 XT PE?
    If so, how did you do it, and to what voltage was it done?

    I have a His IceQii X800XT PE and am currently stuck at 550 maximum core speed and 570 maximum mem speed when overclocking and am trying to get over this apparent wall.

    Any help would be appreciated. Thanks and have a nice day!

    Short version:
    The top picture shows the pin where you measure the voltage. You have to do this while the card is running.
    The second picture shows a resistor. Take a multimeter and measure the resistance on it. It should be around 420. Now take a pencil and draw around the resistor. (Follow the green line)
    The pencil should make contact with the resistor while you do so.
    After a few strokes measure the Ohms on the resistor again. A around 380-385 you're at 1.5v vgpu usually. This may vary slightly from card to card so don't make too huge steps.
    15 ohms less are 0.04volts more roughly.

    I hope this helps.

    Those pics above are taken from another site btw.

    Like you time is a premium... I've done the pencil volt mod on the VIVO pro and vmem, droop mod on my ASUS board. So I'll try to do a section at a time with your pics... send me an email where you want me to send it ....

    Jason, could you share a bit more info on where the other ends of the wiring are connecting to. I have heard of folks attaining speeds like yours, but thought they were just cutting up. I see now that it can actually be done. I am quite capable of doing the soldering work. And I know there are risks. But I am willing to take it. I sent you a PM also, hoping to get in touch with you one way or another. It's amazing that you can get that kind of speed out of the core and memory chips. Geesh.

    I don't think there is a pencil mod for the memory m8.

    Noob question alert!

    hehehhe, ok, for the vmods, will 50k vr's work in place of the 10 and 20k vr's? I assume so, but we all know what happens when ya assume :eek:

    TIA,
