    Hey NBR, little problem here with my 485m...

    I'm running a dual monitor setup, so naturally I run NVIDIA Inspector on startup so that I can still have idle mode on my GPU when I'm not running games. I don't know if NVIDIA Inspector is related but the problem is that sometimes when starting up a game the GPU doesn't set the clocks to normal, so I either have to turn my graphics to low or restart the computer. (It seems to always work fine if the computer has just restarted.)

    Idle clocks: 51Mhz / 125Mhz
    Gaming with bad clocks 74Mhz / 1495Mhz
    Gaming with normal clocks 574Mhz / 1495Mhz

    Does anyone know what's wrong?
    Thanks

    (And yes, games are added to the P0 section of NVIDIA Inspector)

    I think the problem is that idle clocks are unstable with dual monitors. Most manufacturers make their drivers clock the cards up to a medium setting when more than one monitor is plugged in to guarantee stability. It may be that since you are forcing a 51MHz clock, that it is introducing instability into the system causing the strange clock effects.

    Alright, so I disable one of the monitors and turn off NvidiaInspector and it seems to be working for the whole day until tonight I shut down a game and all of a sudden my card starts doing this:

    Basically it looks like the GPU is cycling through the clock speeds at random intervals. The fans go in turn with it and as a result it is incredibly annoying. I've tried flashing to EC 1.00.11 but it didn't change anything.

    What the heck is going on?
