I currently OCing my i5 7600k to 4.6 Ghz and set 1,320 Vcore in Bios . When i run Stress test with Prime95 and OCCT and Aida64 ,those software show that my Vcore is jump between 1.284V,1.26V,1.27V . Are there any resolution to make my CPU run at the Vcore like i set in BIOS ?
Im newbie to OC ^^ correct me if something wrong

Thank you

This is caused by Vdroop. You have to increase your LLC, which increases voltages under load.

This is a good read that explains LLC: https://linustechtips.com/main/topic/24019-load-line-calibration-why-overclockers-should-care/

If it passed your stress tests and doesn't reboot or blue screen on you then it seems to be stable. Increasing your LLC will increase voltages and heat.
