I9-9900K 5.0 Overclock
netanelbb :
... tried to overclock my i9-9900k up to 5.0 and the voltage reached 1.563... but in his video it's at 1.3v... what's going on?
WAY too high!
Overclocking with Vcore in “Auto” isn't recommended because the BIOS will force more voltage than needed, raising power consumption and heat. Prolonged high temperatures can harm components, even with manual settings. Excessive heat may speed up "Electromigration," which weakens traces over time.
The most probable explanation is that you missed the silicon lottery. No two CPUs behave identically. The issue likely stems from manufacturing variations. It may be due to a defect in your CPU, impurities in the silicon, extra resistance from poor bonding with the package, or other factors. It’s possible you received a higher-quality chip than the one you tested.
he shouldn't be reaching 1,563 volts though... that's really intense and likely causes a lot of throttling.

restore settings to default, adjust core speed to 50 and voltage to 1,325
BringerOfTea:
restore to default and adjust core speed to 50, set voltage to 1,325
He advised cutting those voltages right away. Prolonging at 1.5 increases the risk of CPU damage, potentially destroying those small transistors.
Netanelbb explained how to adjust the overclock settings for the i9-9900K, noting the voltage readings differ between his video and what he sees online. He advised against changing the Vcore to 1.5V due to potential risks. He warned that auto-adjusting the Vcore can cause excessive heat, leading to long-term damage and possible failure from electromigration. He referenced a guide on Electromigration and provided links for further reading on overclocking safety.
