How to configure the multiplier for each core.

i am considering trying to overclock this 8350k, but even at very high voltages (1.38-1.39), one of the cores stops working past 4.6ghz without crashing. i understand this from running prime 95 small fft test, where the second core crashes immediately while the others run fine. do you think there’s a way to overclock the other three cores but keep this problematic one at stock or a lower multiplier? temperature shouldn’t be an issue since my 240mm cooler master ai is managing everything under 80c on the cores that can actually overclock.

Intel's Extreme Tuning Utility is designed to adjust the clocks of specific cores.

Thanks! I think I can adjust the voltage for each core too. 1.39 seems a bit too high, so I might lower it to about 1.37 and check what's possible for each core.

I understand that XTU supports adjusting clocks based on the number of cores loaded (checked thoroughly), but unfortunately, there isn't a method to specifically focus on or restrict a particular core to a certain speed.

Which Prime95 release are you using? (No need for versions over 26.6; 27-28.x are recognized to cause thermal/TDP issues...)

Take into account that 4.6GHz could be the maximum for your particular CPU, regardless of any actions taken.

The BIOS should include an option for "all core" or "per core," positioned immediately above the existing all core multiplier setting. This can be done without relying on third-party tools.
