    Bug Report: Intel Extreme Tuning Utility unable to change power limit on Skylake-X processor

    jsgook

      I have an Intel Core i9-7900X processor and a ASUS PRIME X299-A motherboard. I have configured the motherboard to use the default power limits for the processor (140 W TDP), intending to use XTU to override them at the OS level. With the pre-release XTU version 6.3.0.35 available on the ASUS website, setting the Turbo Boost Power Max works as expected. However, with the latest version, 6.3.0.54, from the Download Center, setting the power no longer works. Although I can change the Turbo Boost Power Max to "unlimited," when I run a stress test like Prime95, the reported package power is limited to 140 W, and I observe a frequency reduction.
