[SOLVED] I9-9900K 5.0 Overclock

Solution


WAY too high. Overclocking should not be attempted with Vcore settings in “Auto” because BIOS will apply significantly more voltage than is necessary to maintain stability, which increases Power and heat. We know that excessive heat over time damages electronics, so even when using manual Vcore settings, excessive Vcore and Core temperature may result in accelerated "Electromigration" - https://www.google.com/?gws_rd=ssl#q=Electromigration

This prematurely erodes the traces...
The most likely possibility is that you lost the silicon lottery. No 2 CPUs perform exactly the same. It comes down to factors during manufacturing. Obviously something about your CPU is causing it to not be able to hit 5GHz without a SUBSTANTIAL voltage increase. Could be a manufacturing defect, impurity of the silicon, additional resistance from sub-optimal joining to the package, or any number of other things. He just might have gotten a better sample of the chip than you did.
 


Same bios z390-h
So what should i do? get rid of the the overclock or let it be on 1.5V?

This prematurely erodes the traces and junctions within the processor's layers and nano-circuits, which will eventually result in blue-screen crashes that become increasingly frequent over time. As a rule, CPU's are more susceptible to Electromigration with each Die-shrink. However, the most notable exception is Intel's 14 nanometer Microarchitecture, where advances in FinFET transistor technology have improved voltage tolerance.

Here's the maximum recommended Core voltages per Microarchitecture from 14 to 65 nanometers since 2006:



Your 9900K should not exceed 1.400 Vcore. You need to manually configure your Core voltage in BIOS before you ruin your CPU. You also need to carefully read these guides:
