    Could You help me plese overclock my gpu.

    Actually i'm using windows 7 enterprise 64 bit and 285.62-notebook-win7-winvista-64bit-international-whql.exe.

    I boosted up clocks in Rivatuner and Nvidia system tools but the setting wasn't saved when open it again. I see again 400/600 :mad:

    What seems to be a problem? What should i do?

    T61 and nVIDIA? Are you aware of the infamous nVIDIA bug which is affecting most T61(p) units featuring a discrete GPU? Are you sure you were not searching for a way to underclock your nVIDIA GPU?

    with rivatuner.

    Running long time at 55% overclock, LOL, 625MHz core and 950MHz memory. I went a bit lower to have some margin of error due to temperature fluctuations.

    in rivatuner where you change your clocks, look below where it says "apply overclocking at windows startup" and check that.

    I use 178.74 drivers as with the 2xx.xx it didn't work with that high clocks the first time those drivers got published (not at the lenovo site). Never bothered changing drivers again though.

    P.S. make sure you use TPFancontrol to run your fan at max speed as well when needed.

    I'd suggest that you properly inform yourself about the risks and benefits of a nVIDIA based T61 , and then you draw your own conclusions based on what you learned from your investigations. Good luck with your endeavour!

    You're going to kill your laptop. Unless that's what you want or can afford to have happen, then go right ahead.

    You might be lucky with your T61, so just keep it until it breaks. But then again, a T500 is probably much better in many regards, while still being backwards compatible to many T61 components (docking station, keyboard, display panels). Also, given the uncertainty of the T61's remaining lifetime due to the nVIDIA GPU, i'd already look around for a suitable replacement. See 635845-total-t61-nightmare-2.html#post8204701 for further inspiration.

    I've got 2 profiles in Rivatuner @ my R61.
    "Default" profile @ 200 MHz, which is being set at boot (powersaving),
    And the second profile @ 600 MHz, which I manually trigger by hotkeys when I really need some power ;)
    It's, IMO, best solution - try it by yourself ;)

    I would seriously consider selling it and replacing it before it dies. Once it's dead, it's not worth much.
