Finally, Im sorry for late, but Im busy last days. But there is it. I had some issues with C5F and safe the BIOS screenshot. So after this experience I did all BIOS screens at C5F-Z and with FX-9590. This settings could be OK with good FX Vishera and allinone cooler.
Notes:
the green = less important settings
the red = more important settings for OC
For high clocks always set AMD Trubo core "disabled"
CPU and PCIe spreadspectrum always disabled for high frequency of CPU
DOCP profile helps you in memory settings. Its is something as Asus XMP profile for AMD. Ussually is here one or two profiles. But remember, your effective DRAM clock must be lower or the same as CPUNB frequency!!!
For voltage you can set manual or offset. Offset is more important for safe some energy in power consumption. Its delta from VID of CPU/CPUNB values. remember, every piece of CPU has another VID voltage and every CPU has different leakage (=how hot is it with increase of voltage, how good is for OC). For CPU is max range of 24/7 voltage from 1.425 to 1.55 V (depends on leakage) with allinone type H100, H100i, Thermaltage watter 3 extreme, NZXT Kraken, CM Nepton etc. With these range you can get stable around 4700-5100 MHz stable.
For CPUNB use max around 1.3 V for 24/7. In this case you can doing OC around 2500-2700 MHz stable. The IMC quality is different from quality of CPU chip! CPUNB OC is more hot for chip, more stress for IMC and together for CPU, but impact the performance a bit...
CPU VDDA voltage can safe your unstable OC. Example you are 15min stable and after your PC get BSOD or error. Sometimes +0.1 or +0.2 V can help this issue.
DRAM voltage is OK around 1.5-1.7 V for 24/7. With lower voltage around 1.6-1.65V you can get higher at CPU frequency, the same for DRAM clocks (with lower DRAM clocks around 1600-1866 MHz is more easy to get higher CPU frequency)
DRAM timings, the first 4 are basic classic CL, lower mean better performance, but lower stability. Timings is hard story for many sentences. There is many DDR3 memory chips inside and every is a bit different. With memory issues and tweaking is not basic guide. But at C5F-Z you can see few memory settings for PSC and probably Elpida Hypers...
You can change tRFC time too, lower is for better performance, but lower in stability. Again, all deep memory OC settings is about many, many hours of tweaking and testing. So simple about practice
DRAM drivings, for PSC and another chips can be different, ussually is auto setings OK for 24/7.
Now back to the important settings - VRM and power settings
For high clocks use LLC to High or Ultra High. From my experience its most stable for CPU voltage without drops.
CPU current capability - 140%, CPU want in high OC more juicy from VRM
CPU power phase set to Extreme for high clocks. For middle OC not, because it will be not ideal for VRM (hot, higher power consumption of VRM part)
VRM - try around 400-550 KHz. Again, this is for higher clocks of CPU.
CPUNB LLC - there is not much to say, ussually I do not the maximum of CPUNB frequency, because its very hard to get stable around 2650 MHz, so better for me is something around 2400-2600 MHz.
VRM Over temp protection - better to enabled, you dont want smoke from VRM
All Extreme only for LN2. ..
In NB is some IMC settings for memory. ECC support and Unganged mode is good for higher performance.
Be sure before you save and exit your OC settings, you was at this bookmark setting C1E and CNQ are power savings function. You can let it at auto, for best performance disable it (maybe +1% of performance )
C6 state is OK for downclock in idle.
HPC mode is special computing mode for some multithread operation. But it can be better for stable clocks without jumping the cores frequency in some cases.
APM Master mode is something as main part of power management of FXs. It want the CPU around the TDP limits. So after OC and enabled APM master will your clocks jumping up and down in stress test or hard benchmarks. For OC disable it!!!
