I recently checked 4.7GHz with Core Voltage set to 1.375V and here are the findings.

Excellent results dkD0nkeyniks
Your voltages are steady and no droop at 4.6ghz so your PSU is doing it's job.
Your temperatures are excellent with a good Core voltage. This is a sweet spot and you should save that profile.
OK you can try for 4.7GHz - 4.8GHz without further increasing Core Voltage and see how your temps are.
Remember no more than 1.4V on the core if required for stability.
This is one decent chip you have and definitely above average.
Awesome!
so incrementing voltage by 0.01 if I need to increase it but never go over 1.4V.
I am curious, in the guide that you linked to me, it talks about increasing the HTT/FSB, CPU-NB, HT, and DRAM.
What are the advantages of tweaking these? As in, what do each one of them do?
Yes tha'ts correct and I say that if you want your CPU to last.
The Front-Side Bus (FSB) is the interface that carries data between the central processing unit (CPU) and a memory controller hub, known as the northbridge and connects the CPU (chipset) with RAM memory and L2 cache. AMD CPUs however have the IMC (Integrated Memory Controller) built into the CPU.
Little to gain with FSB overclocks and usually with poor results and improper settings may cause issues such as hardware lockups, data corruption.
OCing the FSB will in effect, increase your HHT and can help with higher frequency RAM. If you want to go that way, just increase FSB in small amounts and adjust RAM frequency to match.
I have an FX-9590 and tried those settings in the guide without any noticeable increase in performance.
Best leave it at default as it is designed to do IMAO.
Good results achieved so far. Voltages remain stable and there’s no droop at 4.6ghz, indicating the PSU is functioning properly. Temperatures are high but within a good range, making this a suitable profile. You can attempt speeds between 4.7GHz and 4.8GHz without raising Core Voltage further to observe temperature changes. Ensure the core voltage stays below 1.4V if needed for stability. This chip is decent and performs above average.
Increasing voltage by 0.01 is acceptable, but avoid exceeding 1.4V. Regarding the guide you referenced, adjusting HTT/FSB, CPU-NB, HT, and DRAM settings can help. These changes may improve stability and longevity of your CPU.
The Front-Side Bus (FSB) connects the CPU to memory controllers and RAM via the northbridge, linking the chipset with L2 cache. AMD CPUs include an IMC built into the CPU itself. Overclocking FSB can boost HHT and support higher frequency RAM, but be cautious—poor settings may cause hardware lockups or data corruption.
OCing the FSB raises HHT and can aid with faster RAM speeds. If you wish to pursue this path, increase FSB gradually and match RAM frequency accordingly.
I tested these settings on an FX-9590 without a significant performance boost. It seems best to stick with default values unless IMAO is specifically required.
When attempting higher speeds like 4.8GHz, I experienced a hardware warning and had to lower the core voltage to 1.395V. I then reduced back to 4.7GHz at 1.375V, which passed AIDA64 testing after a short run. I tried changing the core voltage to 1.385V in BIOS and restarted the PC, but after about 15 minutes I encountered a blue screen and had to restart again.
I followed AIDA64 for a 10-minute test at 4.7GHz and received a restart after 19 minutes. Should I revert to 4.6GHz at 1.375V, or limit AIDA64 usage to under 10 minutes?
I'm not completely aware of all the Bios options with your MB dkD0nkeyniks. Still, you're near MAX OC at 4.6GHz, and ignoring the 100-200MHz won't help much. It's better to stay stable rather than risk occasional crashes, even though you won't face stress from the tester during regular use.
You now possess the necessary tools and expertise to attempt an overclock. Some users have reached 4.8GHz on that chip by increasing the voltage slightly, but I don't suggest doing so.
The likely cause for your higher overclocks failing is overheating in your VRMs (Voltage Regulator Modules) on the motherboard. Some boards have superior and more robust VRMs, which is known as "power phase control." This means that certain motherboards can handle better overclocking than others.

It's better to stay stable rather than risk occasional crashes, even though stress tests don't usually cause issues under normal use. You now have the necessary tools and skills to try improving your settings. Some people reach 4.8GHz by pushing the core voltage above 1.4V, but I don't suggest that approach. The likely cause for your failing overclocks is overheating in the VRMs (Voltage Regulator Modules) on the motherboard. Some boards have better VRMs and this is called "power phase control," meaning performance varies between models. For a clearer picture, check this article: http://www.overclock.net/t/943109/about-...processors. I tried going back to 4.6GHz at 1.375V for over 25 minutes without any errors, so I'm sticking with that setting. Thanks for your guidance throughout!
