Overclocking problems

[D8NzZ]

Recently I bought my new processor i7-9700K and tried to overclock it to 5 GHz. I kept increasing the Voltage reaching up to 1.35 V. I thought that 1.35 V would be enough and not too much for the temps to reach too high. However, I soon noticed that it was stuck at 4.6 GHz even under load, never changing. I use CPUID to check the clock speed. I tried to increase the Voltage again, but it never changed. I'm still new to this but my only idea is that only one core is boosting to 5 GHz, but then again I looked at some tutorials and they all showed 5 GHz overall in CPUID. Is there something I'm not seeing? Thanks

Likely because the 9700k doesn't need to be at 5ghz, 4.6 should handle most loads fine, it'll go up if it actually needs it.

Try 4.8/4.9 at 1.3 (offset ) 

Your chip could likely not handle / your board could not handle it
