Go to BIOS->Advance->CPU config->CPU power management:
1.intel CPU Boost 3.0-> Disable
2.Turbo boost-> Disable
I might name these wrongly, disable anything you see there’s a “boost”.
I kept my speedstep enable though, works for me, if it’s not working:
3.Speedstep-> diable
I hope this could help.
Seems like there are some issues runing WOW with my 14th gen 14900KS.
Note:
This setting make my computer about 50% slow.
Try to set Bios to " intel default setting"
This may only reduce 8~10% performance.
