    Different tweak software could affect overclock stability?

    I used GPUTool to overclock my GT 240M mobile gpu. It's quite safe, the notebook run really cool at default speed. I reached the 330m speed (275/800/1265) quite easily.

    However using nvidia system tools i experienced video kernel crash both in windows and playing battlefield 2 on-line, at the same clock.

    Anyone has a clear explanation for this behavior? :confused: I'd like to use nvidia system tools because i can run it at windows startup ad leave the gpu always overclocked at 3d profile.

    Interesting. That might explain why some of my higher clock tests using NST failed.

    The most stable way to test is probably to flash the BIOS with the settings since it doesn't rely on any software, but that seems like a risky way to do it.

    Edit: I just tested this theory and it didn't pan out. Flashing the BIOS was no more stable than using NST with regard to my system.

    You have to have had some old traces of drivers... i suggest you uinstall everything from NVIDIA , go to safe mode and run driver sweeper and install the new drivers you want and system tools 6.06... if that doesn't work , do a clean install.. it always fixed the problems wih systens tools for me.

    I will test again tomorrow, as i just have a clean system (clean install with "old" but really stable 195.62). :)

    Many of you are speaking about video bios flash, I would like to do it, but which software can read and edit a GT 240m bios? No one at the moment (and I guess it will never be), I tried a lot without success. GPU-Z, NiBiTor, nVFlash can't read my bios file. :mad:

    @sean473 yep I did it with driver sweeper/driver cleaner.net/ccleaner in safe mode, with latest forceware installed.
