    Default NVClock 0.8 Beta 2 Released

    Hi Michael,

    The past couple of months I have been extremely busy with my study and other things. I also didn't have much time for NVClock or Wine hacking.

    Recently I had some time to fix up NVClock and today I'm happy to announce a new beta. The version contains all the bugfixes, rewrites and other changes from the past couple of months.

    More information can be found on

    # Support for ADT7473/W83781D sensors
    # PCI id modding support (Quadro faking)
    # Temperature reading fixes for internal sensor
    # Fanspeed adjustment fixes for NV3x/NV4x boards
    # Pipeline modding fixes
    # Bios parsing fixes
    # Improved (experimental) lowlevel overclocking / clock reading for NV4x/G7x boards

    Thumbs up Very nice!

    I love this program, it's awesome! Glad to hear the author didn't forget about it.

    localhost rwilliams # nvclock -s
    Card:           nVidia Geforce 7800GT
    Card number:    1
    Memory clock:   1071.000 MHz
    GPU clock:      8.883 MHz
    Any idea why the GPU clock is toying with me?

    Can you post the debugging output from NVClock for your card? (-D if I recall correctly, otherwise just look at the help)

    What BIOS version is on your eVGA 7800GT? (Is the card a stock one or a CO variant or what)

    I'll redirect Roderick to this page right now; I believe some users had reported this problem in the past.

    Ahh yes. My BIOS was one that a friend made... he mainly increased the voltage. So maybe that's why. Of course I forgot about that =/

    Are you sure that you are really using version 0.8 beta2? I ask this because the problem shouldn't appear in beta2 anymore as it got fixed. There's no way it can appear.

    I did some quick check on the source and this really is beta1 because beta2 shows some more lines in its debug output when you run -D. Upgrade to the latest version

    Bah, sorry. I didn't notice the '2' in the title, so I did use 0.8b.

    localhost bin # ./nvclock -s
    Card:           nVidia Geforce 7800GT
    Card number:    1
    Memory clock:   1071.000 MHz
    GPU clock:      275.400 MHz
    Much better. Sorry for the hassle
