i7 7700K Overclock help
I need some assistance with overclocking my i7 7700K. I want to push its performance as high as safely allows. I have a decent cooler installed. The only experience I have is reaching 4.8ghz at 1.2v without any issues. I’m eager to try and get it even faster. I’m not very familiar with overclocking and would really appreciate anyone’s guidance to reach my goal. I’m confused about the motherboard settings and how everything works. I understand the basics of adjusting CPU speeds but don’t know the proper steps for a safe and effective overclock. Your help would be greatly appreciated!
You might want to reduce your Core Cache ratio as well, since it doesn't really add much performance gain. I'm using a Core Cache multiplier of 40 instead of the default 42. Also, setting the core multiplier to 49 at 1.325v seems stable. My motherboard is an ASUS Maximus IX Hero.
You have considerable flexibility in your setup.
The suggested voltage range is 1.4 volts with temperatures around 80°C.
Ignore advice from others who claim anything below is risky or above is harmless.
As long as stability is maintained, you should use prime95 v26.6 and perform a comprehensive FFT analysis for most thermal profiles while keeping an eye on core temperatures.
Exceeding 80°C suggests your cooler may not be adequate or the chip could overheat.
For temperatures between 70-75°C, consider increasing to 4.9.
At 65-70°C, you might even attempt 5.0.
It’s wise to reduce voltage by 0.005 at each step in the current frequency range and identify the lowest voltage that still allows stable operation.
Once you reach a point where a 0.05 increase works and the multiplier can be raised by 1, test again.
If successful, gradually lower the voltage by 0.005 until it no longer functions properly, then backtrack a step at a time.
Continue this process until you consistently achieve stable performance at 80°C or 1.4V, or until you encounter any instability.

You have plenty of room to go.
The suggested limits are 1.4 volts and 80c running temperatures.
Don't take the opinions of others who claim anything below is risky or above is actually bad.
You definitely have a lot of headroom if your system is stable.
You should install prime95 v26.6 and perform a big FFT analysis for most thermals, keeping an eye on core temperatures. If they go over 80, your cooler isn't enough or the chip is overheating.
If you're around 70-75, you can try going up to 4.9.
For 65-70, you might even consider 5.0.
I suggest reducing the voltage by 0.005 at each step at your current frequency and identifying the lowest voltage you can safely run.
Once you find that step-up of 0.05 and increase the multiplier by 1, test again. If it doesn't work, go back up by 0.005 until it does. If it works, reduce by 0.005 until it stops, then go back a step.
Keep repeating this process until you reach 80c under load, or 1.4v, or any instability occurs.
Your current temperatures are already in the 80s, which is normal for the i7 7700k. I was told by many people this is typical. It seems to me it's okay. Is it worth considering a water cooling system?
The cooler you possess is acceptable, though you might want to explore options like a thermoelectric cooler, premium air cooler, or a high-end AIO CLC water cooler. These components tend to generate more heat. What is the current room temperature?
When purchasing a high-end cooler, you might achieve a performance boost of around 200Mhz. This improvement is only about 4% and would likely go unnoticed by most users on the PC. If I were facing a similar situation, I’d lower the speed to 4.7Ghz and then adhere to Staplerguns recommendations to minimize the Vcore. This should keep your system under 80C while maintaining strong performance.

That cooler you have works, but you might want to think about a thermoelectric cooler or a high-end air cooler, or even a premium AIO CLC water cooler. These components tend to get very hot.
What's the room temperature?
I set my CPU back to 4.2ghz and left the voltage at auto, but my temps stayed between 29-31°C. Once I tried overclocking, they rose again. Should I switch to a different cooler? Any recommendations? Also, if you plan to start at 4.8ghz, what should your voltage be set to?
At 4.8 try 1.280 and adhere to the instructions from my earlier posts for adjusting voltage levels.
Maintain temperatures at or below 80c during peak times.
For a true overclock, an upgrade would be necessary.

Try a value of 1.280 at 4.8 and adhere to the instructions from my earlier posts for adjusting voltage levels.
Maintain temperatures at or below 80c during peak usage.
For serious overclocking, an upgrade would be necessary.
What is your room temperature?
I’m uncertain, perhaps in the low 70s. What upgrades would you consider?
