    Nvidia 240m overclocking became invalid

    Hello everyone,

    I have a stock 240m card and it usually overclocked just fine. I have recently updated drivers to 306.23 and any overclocking I do in Nvidia Control Panel gives me "The changes made were invalid and will not be applied".

    I had a few stable clocks I could use for games but I cannot apply them anymore.

    I have tried using other OC soft to the same effect, every time everything just returned to normal instantly.

    Rolling back to the old version of the driver did not help at all, still the same issue.

    It also seems like the new drivers are worse for fps in games as well.

    Can anyone think of anything to try and fix that?

    Edit: It seems the card no longer changes the clocks from idle to full when a game is running which is what resulted in performance drop in games

    Edit2: Tried other OC soft, no effects, reinstalling nvidia system tools did not help as well. Seems I am currently stuck on default clocks of 405/324/810 (core/mem/shader) w/e I do, ingame or on battery.

    Anyone got any ideas for a fix?!

    revert to a earlier driver. rule of thumb i always use is NEVER uses latest driver out as theres always something wrong with it.... and clean older drivers off correctly first. hope its gets resolved for you.

    Best thing to try in this situation is to do the full power drain to see if that resolves it (since you rolled back to the older drivers already). Just be sure to pull the CMOS when draining. If that doesn't solve your stuck clocks, try restoring to a time before the new drivers and checking the clocks again. If that still doesn't help, you might have to do a very clean install of the video drivers again. Good luck.
