    Problem after clean install of W10. IDE to AHCI, graphics now laggy


    Clean install just before Christmas, all good.

    After New Years, I realised that my bios was set to IDE. Ssd's work faster if they are set to AHCI. So I changed the bios to AHCI and then performed a clean install.

    Long story short, since swapping from ide which worked fine. To now on AHCI, every time I try to play any games the graphics card lags out. From say 60 down to 7, then 65 down to 10 fps etc.

    Every thing I can think of has been updated.

    What is causing this issue?

    I have read about using the intel RST software and drivers.

    Also my ssd is a crucial 2.5" 128gb.


    What is going on.......

    AHCI vs regular Native IDE


    If you want to change IDE to AHCI in windows 10, without a clean install, do the following steps:

    • Open Command Prompt (Admin)
    • type: bcdedit /set {current} safeboot minimal
    • Restart PC and go into you BIOS -> Set IDE to AHCI
    • Windows 10 will start if Safe Mode
    • Open Command Prompt (Admin)
    • type: bcdedit /deletevalue {current} safeboot
    • Restart and Windows 10 should load with AHCI enabled now

    Until now, I had a 100% succes rate with this, but in the case Windows 10 wouldn't start, go back into your BIOS and set AHCI to IDE.

    W10 AHCI Reverts Back to IDE

    I initially had difficulty with W10 recognizing AHCI properly in order to use my SSD drive. I located a fix which provided instructions to change 2 registry settings:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\storahci\....Change Error Control entry and StartOverride to 0

    I did so and everything works fine for awhile but W10 eventually drops the AHCI controller causing my PC to more or less come to a standstill. The registry changes I made actually revert back to the original settings before I changed both to 0. How strange.
    I have to reboot, disable AHCI in BIOS, change the registry settings back to 0, reboot, re-enable AHCI in BIOS and everything works again as planned...until it happens again.

    Any suggestions why this keeps happening and how I can permanently configure W10 and the registry to always recognize AHCI?

    Thanks

    W10 AHCI Reverts Back to IDE

    I've never received a response after posting my question in Technet. Since that time I've continued to experience the same issue. For now I've given up trying to make AHCI work consistently with W10. I've changed BIOS to IDE and also changed back the registry
    settings. I'm hoping I see no new problems arise. If so I'll repost.
