[SOLVED] Need help with my i5 7600 3.5ghz Turbo boost not working

[Mislav_1]

Hello there. I had this i5 7600 3.5ghz since 2017 and turbo boost never worked for me. It is enabled in BIOS. I don't know what to do.
My motherboard is ASRock Z270 Pro4

was it upgrade? did you do a fresh os install for it?
what under system info?
do a stress test?

There's something usual here, your CPUID identify it as 7500 , your Task manager reports a 7600. BUT the base clock is 3.4ghz on 34X which is a 7500 and Not a 7600.
You shouldn't be on 34X if you have a 7600, should be 35x/ 3.5ghz.
Something is not set right in your BIOS. see your MAX boost clock is 3475ghz, that's exactly your 102.2 base clock X34. so it looks like you have configured your CPU wrongly in Bios. although u have enabled Turbo boost, but you must have set the multiplier wrong BOTH in base clock and Boost settings.
