It would be a great overclock with impressive results at 4.7GHz using an Air cooler and maintaining temperatures around 60C with P95. There seems to be some issues here. I don't see the 4.7GHz listed, and HWMonitor shows a maximum frequency of 10247MHz which doesn't match. Also, your core voltage is too high at 1.488V if you want the processor to last longer. It would be best to aim for a maximum overclock without exceeding 1.4V on the core. Your approach is up to you, but it might not be safe.
This would be a very good overclock with impressive results at 4.7GHz using an Air cooler and temperatures around 60C with P95. There seems to be some discrepancies here. I don't see the 4.7GHz listed, and HWMonitor shows a maximum frequency of 10247MHz which doesn't match. Your core voltage is also too high at 1.488V if you want the chip to last. It would be best to aim for a maximum OC without exceeding 1.4V on the core. Please let me know how you plan to proceed, but I'm not sure it's safe yet.

There seems to be a significant overclock adjustment here. Achieving 4.7GHz with an air cooler and temperatures around 60°C using P95 is highly unlikely. The readings from HWMonitor show 4.2GHz, and the maximum frequency displayed is 10,247MHz, which doesn’t match. Your core voltage is also too high at 1.488V if you aim for long-term stability. It would be better to target a maximum overclock without exceeding 1.4V on the core.
Your approach is up to you, but it looks unsafe. I’ll try again following your guidance.
Should I go with AIDA64 Extreme?
The earlier guide recommends disabling Core Performance Boost, C1E, Cool n' Quiet, and C6 Support. Are there any other settings I should adjust?
Yes, the self-extracting .exe is what you need. It’s a free trial version for a month, which should be sufficient to resolve the issue.
The instructions are accurate—disabling sleep or CPU states can help with stable overclocking. They’re just power-saving features that can be reactivated once stability returns. Disable Turbo Boost, Cool and Quiet.
For now, use your multiplier at 4.4GHz and a core voltage of 1.375V, keeping the rest on Auto. You can enable XMP profiles for RAM if desired.
Before proceeding, observe what happens at 4.4GHz with a fixed frequency.
Avoid making random changes in BIOS without understanding the impact. Increasing voltage exponentially raises heat, making stability harder to maintain.
Keep in mind that 100-200Mhz won’t noticeably improve performance; focus on an OC based on ambient temperature. A stable setting during winter might be too hot in summer, so save profiles considering seasonal changes. Your BIOS should support these profile saves under Tools.

There could be a significant issue here. The reported 4.7GHz isn't present, and the HWMonitor shows a frequency of 4.2GHz with the maximum at 10247MHz, which seems inconsistent. Additionally, the core voltage reading is too high at 1.488V if stability is the goal. It would be better to aim for a maximum overclock without exceeding 1.4V on the core.
Your approach is up to you, but it might not be safe.
I’ll restart and follow your instructions closely.
AIDA64 Extreme appears to be the right path based on the guide you shared.
It mentions disabling Core Performance Boost, C1E, Cool n' Quiet, and C6 Support. Are there any other settings I should adjust?
Yes, the self-extracting .exe is recommended—it’s a free trial version that should suffice for troubleshooting.
The guide advises turning off all sleep or power-saving states, as they can hinder performance optimization. They recommend disabling Turbo Boost, Cool and Quiet, and leaving everything else at Auto.
For now, use your multiplier setting to reach 4.4GHz with a core voltage of 1.375V, keeping the rest on Auto.
You can also enable XMP profiles for your RAM.
Before proceeding, check what’s happening at 4.4GHz with a fixed frequency.
Avoid making random changes in BIOS without understanding the impact—the higher the voltage, the more heat it produces, and it becomes riskier.
It’s important to note that 100-200Mhz won’t significantly affect performance; focus on an OC suited to your environment. A stable setting for winter might be too intense for summer. Your BIOS should support saving profiles in the Tools menu.
Here are my observations:
- Changing the core voltage in BIOS doesn’t update the voltage display as expected, staying at 1.35V despite adjustments.
- The core speed and multiplier readings seem incorrect; they drop unexpectedly when using Snipping Tool.
- On CPUZ, the display works properly, but the core voltage drops to about 1.368V during stress tests, then back to ~1.320V when testing is off.
This information should help you fine-tune your settings safely.
The results are solid at 4.2Ghz with great temperatures, so attempt 4.4Ghz and recheck.
The core voltage performs better at 1.332V; if the OC fails at 4.4Ghz, increment the core voltage slightly in small steps until stability returns.
Once stable, test again at 4.6Ghz with LLC enabled in a high but not extreme setting.
If your CPU has sufficient current capacity, increase it to 120%. Maintain the same core voltage and adjust as needed if stability isn’t achieved. Keep repeating the process.
Are you following the instructions correctly?
Your open-source HWMonitor doesn’t display all rail voltages (12V, 5V, 3.3V) for load testing the PSU.
I use HWMonitor from CPUID because we’ll need these values to detect voltage droop when aiming for maximum OC.
Don’t worry about CPUz readings or fan control—we already have all the necessary data from AIDA64 and CPUID HWMonitor.
The results are promising at 4.2Ghz with excellent temperatures; consider testing at 4.4GHz and adjust accordingly. The core voltage performs better at 1.332V, and if the OC fails at that frequency, gradually increase it in small increments until stability is achieved. If stable, proceed to 4.6GHz with LLC set to high but not excessive. Adjust the CPU current capacity to 120% if needed, keeping core voltage constant and increasing it again if instability persists. Continue testing. Your open-source HWMonitor doesn't display all rail voltages (12V, 5V, 3.3V), so check your PSU under load. I use HWMonitor from CPUID to track these values when aiming for maximum OC and detecting voltage droop. Don't worry about CPUz readouts or fan control—we have all the necessary information from AIDA64 and CPUID HWMonitor.

Results: 4.6GHz 1.375V at Medium LLC. Available choices were normal, extreme, medium, standard. No high option.
Great performance from dkD0nkeyniks
Your voltages remain stable with no droop at 4.6ghz, indicating your PSU is functioning well.
Core voltage stays optimal, making this an ideal configuration—consider keeping that setting.
You can attempt running at 4.7GHz to 4.8GHz without raising core voltage further and monitor temperature changes.
Ensure the core voltage doesn’t exceed 1.4V if stability is critical.
This chip is solid and definitely above average.

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?
