    8600 gts switch frequency mod ?

    Anyone having details about that mod ?
    I remember at 7900 was the complete solution for freezings...

    It must be somehow cause I see the ISL controller...


    Thanks

    There is a frequency selection pin on nearly any of these controllers. Just have a look at the datasheet. It's not that difficult.

    sorry guys, what is this mod about? a hw switch that can control freq? that would be cool if paired with a voltage switch too
    imagine, 1.8V and 800mhz core in 3D, then switch the switch and you have stock Vcore and freq.
    Is that the way how it works??

    No, you misunderstood.

    It's not about the chip's frequency, but about the switching frequency of the PWM controller.

    Well..no..With some words it helps to oc...

    As i said in first post... " I remember at 7900 was the complete solution for freezings..."

    And so helps at 8600 GTS too...

    Here we are...



    Resistor in red is switching frequency.

    Default 42 kohm
    After pencil mod 20 (half)

    And so...I can play so far at 945mhz Dirt without freezes.I'll test it more l8r...

    Yup thats exactly the problem I had (well actualy after some minutes not hours lol)

    But only overclocked too high...
    (if this happens on default speed then its driver problem)

    Now I can play without freeze and this ''a driver had stoped responding etc..'' message...

    Hmm, think he need a VERY high res.

    He must see the transistors on the PCB to see which it is.
