    Did I just destroyed 3 cores?


      Hi there, I have realy weird issue. With latest bios update I decide to over clock my ryzen 5 1600 a little.

      In first place I went to the bios, adjust voltage a little and increase cpu speed up to 3,7ghz (I think thats not much)

      After that I decided to go for Ryzen master utility, by accident I instaled the one for threadripper instead the other one.

      Threadripper app showed that I got all 6 cores working but didnt allowed me to change a anything So I go with reinstalation.

      Instaled the correct app and it changed my cores down to 3 out of 6 and threads to 6 out of 8 (cpu-z data).

      I just restared cmos and reinstaled ryzen master utility, nothing changed.

      Master utility wants me to restart my PC if I want to able all cores, but that doesnt help.

      If any one got some solution please help.

            Problem was coused by Ryzen master utility, It was overwriting settings from bios.
            It was diagnosed with use of PowerShell by Great guy @Amd_Robert if you read this thank you.

            Also thank you @iWalkingCorpse for spending with me 7 hours trying to fix it u both are greate guys.

            Going back to PowerShell all you need to do is check how many threads it launches with by command-BCDEDIT

            In my case it was launching with: that is numproc 6 that is 6 threads. (My cpu got 6 cores 12 threads)

            Fixed that by command: BCDEdit /deletevalue numproc

            And rebooting.
