Not surpassing stock clock

[alonseras9]

Hi, I have recently changed Mobo CPU and ram to a MSI z370 a pro i5 8600k 16gb ram 3000mhz I reinstalled windows into a HDD and everything went ok so I cloned it into a ssd and now my i5 8600k doesn't go over 3.6ghz
Turbo boost is enabled in bios
Even with a manual overclock it doesn't go above

Love that CPU.

Strange issue. How are you monitoring CPU speed and stressing the CPU to try to get it to boost? Do you have the Intel Extreme Tuning Utility ? I like it because it will tell you if the CPU is being throttled for any reason. Other than throttling, my only other thought is the windows power plan, but I assume you looked at that.

Yeah I did all u said

With task manager and Riva tuner

srsly task manager?
rivatuner will tell u just all core speed, not core boost
better go with hwinfo64

Hwinfo 64 playing Fortnite it says all cores 3600mhz x36

Ok I solved it(kinda) I went to bios set all default, active xmp for ram, auto voltages and manual overclock to 4.1ghz (i5 8600k max GHz when using all 6 cores) and now hwinfo and intel extreme tuning detect frequency as it should (task manager doesn't XD) and also Riva tuner tells 4.1ghz

In conclusion all I did was simulate turbo boost by locking frequency on 4.1ghz which is this cpu's highest boost frequency when using all cores

Seems I got back from dinner at the right time ... thank you Kerberos for the help.

I definitely solved it, it was a driver problem, device manager showed a yellow triangle in cpu cores, and by following a Microsoft's guide i managed to fix it and now turbo boost applies correctly
