    Since I dont want to spend money just yet on a new computer, I recently tried overclocking my GTX 260M with nVidia system tools. Figured Id try going from stock 550/800/1350 to around 600/950/1500 (650/1000/1600 crashed).

    According to gpu-z the gpu is indeed clocked, but according to the sensor in gpu-z the speed during gaming is 383/301 MHz (core/memory) no matter if I oc or not.

    Even if theres a multiplier in play that I dont know of, why doesnt the speed increase at all? Is there a setting somewhere that throttles the gpu? Id like to at least run it at stock speed..

    Energy settings at performance (playing plugged in). 3DMark06: 10100, 3DMark Vantage 186.xx: P4000, 3DMark Vantage 266.xx: P4400, 3DMark Vantage 266.xx OC: P4800.

    Edit: Didnt mean to put this in owners lounge..
    Also, testing is done during 10 minutes of playtime in Bad Company 2, gpu-temp stays around 55-60 C, clock constant at 383 MHz.

    Sounds like power-mizer (or whatever Nvidia calls their power saving feature now) may be to blame, might have to turn it off or set it maximum performance. It seems like that would be it, since your card never goes above 55-60c.

    Found an option for energy-saving in the nVidia control panel. Changed it to maxium performance. After another run at Bad Company 2 at stock clocks the log showed 550/800 MHz (stock). Good news! Will try with oc later.

    Overclocking with nVidia system tools wasnt too stable. Games kept crashing and the clocks were locked to 383 MHz again. Only reboot fixed it.
    Overclocking with MSI afterburner went better. Seems stable now at 600/1472/900.

    Anyway, why on earth would they tuck away such an important setting? Somewhere in the nVidia control panel, among 20 other settings, I had to choose "I prefer maximum performance". Seriously. I've been gaming at 70% performance for two years.. And no, I havent logged the clocks before, I took for granted my precious was running at stock speed.

    Btw thank you Mike570U!

    Glad you got it straightened out. Same thing happened to me back with my Geforce Go 440 (64MB ram!).

    I think manufacturers sometimes take it for granted that users will be digging around in the display settings drivers, when, many don't.
