    Hello,

    I have a clevo m570ru with a 8800m GTX in it and I intended to lower the 2D clocks and the voltage of the GPU with a bios-flash. Flashing went fine but now the 2D-clocks are not used anymore. It instantly jumps to power-level 1. With ubuntu and coolbits I found out that the GPU works stable running 105Mhz Core and 60Mhz RAM-Clock (I could not change shader clocks).

    what can I do to lower the 2D-Clocks and have them applied?

    Thanks in advance
    Adrian

    Using Nibitor you can do that if I understand you right!.There is a guide somewhere in the forum on how to use it.

    odds are you lowered the 2d clocks to much and it needs to jump to higher clocks. When I experimented with lowering the 2d clocks on my d901c, I was able to lower them, but just opening a firefox caused the gpu's to increase the clocks.

    Is it possible to force 2D clocks? I could also reduce the next clock level to 2d-clock-level (or below). I will try ;)

    You can reduce it as much as you like.But the system might freeze if it's too low!.

    i think i found the lowest clocks that are possible without freezing:

    it runs a bit cooler now and the fan turns on less frequently :)

    GPU:.....200 -> 155
    Shader:.400 -> 310
    RAM:.....100 -> 58

    well the problem is that even the windows 7 3d-windows-switching stutters quite a bit ;) but that is ok for me
