Dude, I really wanna help you out because I had the same problem and it took ages for me to fix..
1. don't use fmax enhancer it will just clock stretch to infinity in my experience, set it to disabled
2. go to digi plus power control and set switching frequency for cpu, soc etc. to manual and set the maximum possible value, so 500mhz or so i think.
3. set Cpu vcore LLC to level 1 you want this because you want high voltage when the load is low (singlecore or 4 core load etc.) to get high frequency and to get a high droop (lower voltage) when there is a big multi core load on the cpu.
4. set stable ram settings so 3600c18 or so don't know if you have b-die chips. we only want to test cpu at first to make sure this one thing is stable.
5. I personally have cppc and cppc cores as well as power supply low idle current and c-states enabled so I would suggest that but it's more of a preference topic, but as a german I need my things to be efficient xD
6. set Vcore to auto
7. now you have 2 or 3 different pbo's hidden in the bios which is sad because it's just confusing the *** out of people. Set the pbo in the main menu where your vcore etc. is to auto i think but maybe I have it disabled, am not at pc right now sry.
8. go to advanced/amd overclocking where the curve is and set to manual limits.
- Set these to 200/200/200 for the first trial.
- maximum boost clock override frequency to 0
- scalar to auto
- finally set curve allcore to negative 30 when it booted before if not, try it and if it doesn't boot just lower by 5 until it boots.
9. open cpuz and do a quick benchmark of multi and single (score should be around 660-710 single core now and multi core should be 13200-13900
10. if you want maximum cpuz singlecore to tell your friends how sick of an oc dude you are, go to hwinfo64 and look at what core has the number #1 out of all of your cores attached to it, set the curve for this core to negative 30, max boost clock to 200, open cpuz, set threads to 1, enable flight mode in windows, open task Manager, go to details, rightclick cpuz and set to high priority, rightclick cpuz in task manager and open core allocation menu, click all cores once so all checkmarks are gone then set the one best core you set to -30 in bios. remember core 4 in hwinfo should be core 8 if it starts at core 0 in task manager because you have hyper threading cores inbetween the normal cores. Now, dont click on ok ans close the menu just yet, run the 1 thread benchmark so just around 1 second is left in the bench and then press ok and close task manager so you have as little things runningas possible. let bench run and Score should be around 700-720 for 1 core
