I'm facing windows 10 slow/non-responsive behavior (perhaps after 1809 update) and after doing many fixes mentioned online (like drivers update, services on/off, windows update etc) i ended up in finding a cpu frequency change.
When i run it in safemode, it run fast as expected on correct frequency 2Ghz. (see core speed)
Where as when i run it on normal mode, starts fine but after few minutes of idle time, it changes cpu freq. way too slow 0.4Ghz. (see core speed)
Initially i thought it is due to thermal condition of cpu, so i tested it with coretemp and it seems fine.
I also tried changing power plan (default to balanced on 1809) to high performance but no result.
I also tried setting SpeedStep to 'disabled' from BIOS but no change. Also updated BIOS to latest from Dell Update App.
Can any one help?
Answer
I found answer myself, it seems to be a close duplicate of this.
Solution:
Another such setting is BD PROCHOT (Bi-directional Processor Hot), an emergency throttling system that is used when a CPU hits its maximum temperature. To disable it temporarily, download ThrottleStop to check on and disable BD PROCHOT. ThrottleStop when running can also correct several types of CPU throttling. Again, if this helps then something is wrong with your motherboard.
