The i7-7700k isn't capable of exceeding a speed of 4.5ghz
The process indicates it has started, which may vary depending on the direction. As discussed in my previous message, I'm referring to stability rather than a boot. It suggests checking if the overclock remains consistent at 1.4v through stress tests. Basic guidance is provided in my earlier post. The recommended duration for a stress test isn't specified here.
I think it would help to go over the testing procedure in more detail, especially since I sense you're not very familiar with overclocking.
Adjust the voltage to 1.4v and the multiplier to 47 to achieve a clock speed of around 4.7Ghz.
Execute the heat test using Aida64, applying only this stress and ensuring no other tests are running.
Keep the test running for 15 minutes.
If your system crashes, freezes, or hangs before the time expires, achieving a 4.7Ghz at 1.4v won't be feasible with the available cooler.
In such cases, you should settle for 4.6Ghz at 1.3v, which you mentioned could handle the stress tests well.
If you successfully complete the 15-minute test, pause the process, restart the PC, and enter the BIOS settings.
Lower the voltage by one step to 1.39v and repeat the heat test for another 15 minutes.
If this succeeds, further reduce the voltage by another increment to 1.38v and attempt again.
Continue this cycle until any instability occurs, then return the voltage to the previous setting that passed the 15-minute test.
After stabilizing, carry out a longer heat test lasting two consecutive hours.
During this extended period, if instability arises, increase the voltage back to the last stable level before the test.
Once you've restored the voltage to its prior safe setting, conduct a full-length heat test for at least 2 hours.
If you encounter any issues during this extended run while operating at 4.7Ghz at 1.4v, revert to 4.6Ghz at 1.3v and continue.
If instability occurs at lower voltages than 1.4v, simply raise the voltage slightly, ensuring you stay within your limits.
Once you can consistently pass the 2-hour heat test at whatever speed was necessary, proceed to record the other CPU stress test options in Aida64 so the full load can be evaluated.
Run this comprehensive test for a minimum of 6 hours straight.
If you manage to complete it without failure, you may extend the duration by an additional 2 hours if desired.
After successfully passing both the 2-hour and 6-8 hour tests, you can move forward with the load line calibration as described in my previous guidance.
In reality, this approach could also be applied if you need to adjust to 4.6Ghz at 1.3v instead of 1.4v.
If 1.3v proves unstable enough for a 2-hour test, simply increase the voltage by one step until you achieve stability.
I aim to have made this clearer for your understanding.
Should you require a more detailed explanation of any part, please inform me so I can expand further if needed.
Key questionsPengwen suggests going through the testing procedure more clearly, as it seems you have limited knowledge about overclocking. Adjust the voltage to 1.4v with a multiplier of 47 to achieve a 4.7Ghz clock speed. Execute a heat test using Aida64 without any additional stress—only focus on the heat test and ensure nothing else is active. Continue the test for 15 minutes. If the system crashes, freezes, or hangs before the time expires, achieving 4.7Ghz at 1.4v isn't advisable with the available cooler. In such cases, you should settle for 4.6Ghz at 1.3v, which you mentioned could handle the stress tests well. If you successfully complete the 15-minute test, pause the process, restart the PC, and enter the BIOS. Lower the voltage by one step to 1.39v and repeat the heat test for another 15 minutes. If successful, further reduce the voltage to 1.38v and attempt again. Repeat this cycle until instability occurs; then revert the voltage to the setting that passed the initial test. After stabilizing, conduct a prolonged 2-hour heat test lasting two consecutive hours. Should any instability arise during this extended period, increase the voltage back to the previous stable level before restarting. Continue this adjustment process until you reach a consistent stable result. Once you achieve stability at the desired speed, proceed with the full load test for at least 6 hours straight. If you manage to complete the 6-hour duration without issues, extend it by an additional 2 hours to confirm reliability. After successfully passing both the 2-hour and extended heat tests, move forward with the load line calibration as described in my previous guidance. It may be beneficial to set up the load line beforehand by performing short heat checks to monitor voltage droop. This approach remains consistent whether you opt for a 4.7Ghz at 1.4v or a 4.6Ghz at 1.3v overclock. If you decide to proceed with 4.6Ghz at 1.3v, consider adjusting it up by one step until stability is confirmed. I hope this explanation is clear enough for your understanding. Please let me know if you require a more detailed breakdown of any section so you can grasp it better.
