    Hi everyone,

    I was wondering if anyone have tried / any experience / any knowledge about what/and/or how the new features and voltage control can be used when overclocking the GPU on the Vaio Z11/12 ??

    EVGA Update:
    EVGA | Software | EVGA Precision

    It seems the Default voltage on the detected 330m is 0.850V but it also seems that we can increase this... normally that would mean more overclocking + more power = stable overclocking (assuming the gpu doesn't overheat).

    EDIT: After trying things out, to my great disappointment it seems Sony has locked (as always) the voltage on the gpu as well :/ So can't actually change it.

    I am running with the Hacked Bios, would it be possible for anyone with knowledge to unlock such through a bios too?

    Anyone tried/ want to try? know anything about it?

    I haven't ever come across anyway of undervolting the Z gpu or even the CPU on these new Z1's..... but if you do find out, let me know please.
    i just want to manage heat, not overclock...

    the gpu run's pretty fine and generates little heat (compared to cpu) and very overclockable, but the cpu is a heatwave....so that limits the gpu overclock as they both sharing the same heatsink in very close proximity =(

    i think you could maybe contact one of the author of such tools as nvbios or nibitor to see why the dont support the 330m in the tools. other mobile chips can be read by those tools and once you dump and mod the bios then flash it, the voltage is applied..

    and then there's the possibility that the bios is effecting the voltage of the gpu also? i don't know what to think because im talking from exerpience of the desktop gpu's, so probably they work because the bios is on the card itself...but notebooks might be different

    I think C2D were the last mobile CPUs from Intel that were software UV-able. Newer ones, AFAIK, hit a brick wall a while back.
