Many users with similar CPU and board tried boosting the CPU to 4.8GHz, achieving good boot times and stable benchmarks. I experimented with different CPU ratios (x46, x47, x48) and set core voltage at 1.280. Only x46 managed to boot and run a test, but after an hour it crashed and required lowering the voltage again. Both x47 and x48 failed to start properly, freezing during Windows loading or displaying a critical error message that triggered the blue screen with the repair option. I attempted various adjustments, gradually increasing core voltage until it reached 1.4, but the system still wouldn’t boot. I changed the CPU loadline calibration settings and switched modes from Auto to Adaptive, Override, and then to different control options. I’m quite new to overclocking and need guidance. Please help.
I think it would help to explain the testing process more clearly, especially since I have a limited understanding of overclocking.
Adjust the voltage to 1.4v with a multiplier of 47 to achieve a clock speed of 4.7Ghz.
Execute the heat test using Aida64 and ensure only this test is marked as successful; avoid any other stress tests.
Run the test for 15 minutes.
If the system crashes, freezes, or hangs before the time expires, you won’t be able to reach 4.7Ghz at 1.4v, and it’s not advisable to push beyond that voltage with your cooler.
In such cases, you’ll need to accept a performance drop to 4.6Ghz at 1.3v, which you mentioned could handle the stress tests well.
But if you complete the 15-minute test, stop it and restart the PC.
if you've tried higher voltages with no effect, then it just might be that you lost the silicon lottery and that's as far as that chip will go.
Not all CPU's are created equal and they are only guaranteed to run at the stock speed that is set for them and the turbo speed.
most everyone can at least overclock all cores to the turbo speed, but anything beyond that is not a guarantee at all and is entirely up to your luck in getting a good chip from what we like to call "The Silicon Lottery" since it's a gamble of sorts whether or not you get something good and capable.
And since the turbo of the 7700K is 4.5Ghz, and you are overclocking to it, that just goes to show you at least got an average chip and didn't get screwed with a chip that didn't overclock at all.
however, it could be that you missed something or didn't do something right, so here's a guide you can follow.

Hope it all works out for you and good luck.
You require greater voltage than 1.28 to achieve a higher overclock, according to what was mentioned. If you look more closely, he said he attempted to increase the voltage up to 1.4v without any change.
What kind of CPU cooler do you have? Your model is the Nzxt Kraken X62.

What CPU cooler?
My cpu cooler is the Nzxt Kraken X62
doesn't sound like you're hitting any thermal walls then.
Refer to the guide I linked you to and see if there's something in there that's different than what you did or if there's something in there that you missed doing entirely. Could be why you're not getting past the turbo speed on all cores.
Does your motherboard support preset overclocks? Yes, though it failed at 4.5ghz. I observed the temperature during the crash, which was around 60°C. I believed 4.5ghz was stable, but now I wonder if it wasn't because I recently tested it at that speed.
