    Hi all!

    I have a PowerColor PCS+ HD7870 Myst. Edition 2GB - Tahiti Le but i cant change the VDDC.
    I tried with Trixx 4.4b, Asus GPU Tweak 2.2.9.9, PowerUp Tuner 0.2.1, MSI AB 2.3.0.
    The card uses a CHiL CHL 8225 for voltage control. It offers monitoring and software voltage-control features and is well supported through overclocking software.

    I found this review. They are using Trixx 4.6 but I can't find it.

    Pls, help me find out how can i change the voltage. Default boost voltage is 1,256V.
    My card running 1260/1725 @1,256V, but i want under voltage it, and find out how much voltage needed to 1100Mhz.

    And if you have a solution how can i disable the boost then pls tell me. I tried 7950 non boost bioses, but not working.

    Thanks!

    The new version of Trixx will support it, but it's not publicly released yet. Should be any day.

    Thanks for fast response!

    I hope i can undervoltage it because the card is very very warm. :mad:
    If i set the lower voltage then this will be the default 3D voltage or the boost will overwrite it ?
    If i cant overwrite the boost voltage then does not matter what i set.

    Any update on when this will be released?

    Thanks for your hard work on this essential piece of software, by the way.
