Thanks for answer. I followed the path where XFR and PBO should be for my motherboard but... I dont have such options in bios. Maybe if I find someone who is using same board and cpu... asrock b450 fatal1ty gaming k4 with 3.90 BIOS. IF other mb brands are boosting to 3.7GHz same CPU then there is something wrong with AsRock. Btw I have boost to 3.8GHz(recorded by HWMonitor, prolly for very short period) but its single or 2 cores not sure. Im specifically talking about all cores 99% of the time during heavy benchmark.

I dont have this options in BIOS. I read that only "X" CPUs have that, is it true? (I saw only Core Performance Boost in my BIOS) Im using GAMMAXX 400, never seen CPU more than 54c so far, good case airflow too. Today I did clean install Windows 10, all updates, latest AMD chipset drivers etc. And on old win and now on new fresh install, no difference. All cores reach only 3440MHz.

Hello, a question to 1600AF owners. What is your all cores boost in heavy multi-core and sustained workloads like cinebench and what motherboard? I see in reviews of the cpu, that is keeping 3.7GHz all cores, but my is only 3.4GHz like an old 1600AE model. Still dont understand how some people have higher boost. Temps are fine, 51C-54C in Cinebench. Not sure if is MB/BIOS issue. Feels like the motherboard is not making difference between 1600AE and 1600AF. https://i.imgur.com/r6vVrgA.png
