Hi all,
My CPU I9 13900HX has clock speed limitation after restart and the max turbo boost clockspeed is capped at 3.9ghz after I restart my laptop. If I shut down and power on, the CPU has max turbo boost speed. This also happens on the latest microcode as well, 0x12B.
I reinstalled windows 11 to see if it resolves this problem and it was a software before it rewrote the speed shift register of my CPU. Just after I booted and several restart cycles, my CPU worked great without any problem, until the latest Windows updates installed (I can't recall which ones exactly). Just after everything was up to date, the clock speed limitation has come back.
I have the latest BIOS installed, but I don't think it is related to that as that would mean so many users would have red flagged this issue already but apparently this has not happened. I started using this BIOS version since it was released from back in 2nd of August and I didn't have any problem like this.
However, if the root cause of this because of a Windows update, why I can't see so many comments on the internet of this same issue?
If anyone knows what is causing this and is there any fix (apart from disabling intel ppm driver in the registry) please let me know.
Thanks.
