Assistance with overclocking

[PlanetZing]

Hi guys, I need some help with an overclocking issue im having. The MSI bios (most current version) will not let me overclock my i5-8600k beyond 4.3 GHz, and wont let me change any CPU voltage settings. To be specific, i cant enter any value above "43" in the core ratio setting, and the only voltage settings i can see are for DRAM and PCH. I am in Expert mode, No error messages, no issues with stability running at 4.3 GHz, and with my Kraken cooler the CPU doesnt get above 45 degrees C even under full load, so i know i can squeeze out more power. If anyone has experienced this issue or knows what might be causing it, please let me know. Thanks!

 

Edit: The motherboard i'm using is a B360i that has been updated with the MSI bios released in December (the most recent i could find)

B360 doesn't support overclocking. You need a Z370 board to overclock. You can get an all core turbo of 4.3 GHz by adjusting the core ratio, like you've done, but you can't go any higher.

Ouch, wish I had checked before. Thank you!
