UEFI 2501 has restored mouse function in UEFI for me.
I believe Ryzen Master does not use ASUS WMI. This can cause Super IO chip to go whacko and lose PWM.
I have used multiple instances of CPU-Z, concurrently with single instance each of HWINFO, AIDA64 and ASUS TurboV Core v1.02.02, encountered no issues. The moment I leave Ryzen Master open for a while with these apps open I lose PWM on fan header CHA_FAN2, restulting in no fans spin as and H_AMP goes to max, resulting in DDC pump at max.
SIV can show which apps are using SMBus locking, must check RM with it.
Intel Defector :eek: AMD Rebel
