    Hi,

    My machine completely died this weekend and my backup with the registry key's to disable powermizer completely went with it.

    Would it be possible for someone to post the keys to disable powermizer via the registry for me. I, and my dog, would greatly appreciate it.

    Thank you.

    Comparing the registry entries before and after using the Nvidia PowerMizerManager (you can download it from the "software.informer" site if you see the result on google

    Looks like this [​IMG] )

    Lists these entries

    Code:
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{yourid}\000*]
    "RmRCPrevDriverLoadCount"=hex:02,00,00,00
    "PowerMizerEnable"=dword:00000000
    "PerfLevelSrc"=dword:00002222
    "PowerMizerLevel"=dword:00000000
    "PowerMizerLevelAC"=dword:00000000

    I think this from the tools "Disclaimer" window explains it better than I could :p

    IIRC I've read about it that somebody used that to eliminate microstuttering or something. PowerMizer only seems to be used for mobile gpus anyway so I never really bothered to do any tests.

    I use powermizer only to disable the overheat slowdown. If I don't disable it, the gpu suddenly drops its p-state when it's "hot", resulting in either crash or very low fps(depends on the game).
    It's also possible to force the gpu to work on minimum, medium, maximun or adaptative clock, but I never had problens with the clocks, appart from the badly optimized games, of course.

    Hi,
    I have a pretty similar question, so don't create new topic. Please help me to find registry keys for Windows 10 and change powermizer to max performance. Now I'm on Win10 21H1 x64 switched from Win 7 x64 and with last one NVPowerMizerManager worked perfectly but in Win10 it crashed with "NVidia registry key not found. Check debug console for more details." In console program not found needed registry values and stoped with message "(PMZMGR) --> Key not found! This software will work only with NVidia cards."
    Now GPU frequency dropped and I'm getting ~60% performance compared to old Win7 with NVPowerMizerManager set to high with no limits.
    Maybe you know how to make NVPowerMizerManager work and see my card (Optimus, Intel+GT 620M). Check some different drivers (Intel included) with no luck. Simple way in back to Win7 but I want to understand the reason why PowerMizerManager cant find needed keys in registry... Maybe in Win10 powermizer keys moved to other section?
    My settings:
    • Checked "Enable PowerMizer Feature";
    • Fixed Performance Level both on Battery and AC adapter -> Maximum without any Throttle;
    • Checked "Overheat Slowdown Override" to NO ANY F** SLOWDOWN (sory... but I hate NV slowermizer)

    That's because you are responding to a topic from 2016!
    Searches online show current Windows 10 doesnt have PowerMizer any more, hence what you are trying to do doesnt work.

    Whoa.... I remember posting this thread eons ago. Man, Nvidia still blows. Powermizer 1.01, it's hosted on a Russian site will lock your max performance speeds of doom. But I feel, humbled... sniff.
