    Is there a link to download the original version of Intel management engine interface driver for Predator Helios 500 to get XTU undervolting unlocked again.

    I fixed it. I uninstalled all instances of Intel XTU component device drivers in device manager and uninstalled latest version of intel XTU.  I then installed an older version of intel extreme tunning utility (XTU) version 6.5.2.40. Now I have undervolting again and no power limit throttling.

    Wish we didnt have to undervolt to get the full cpu potential in Helios 500.
