Help with 9600k overclock

[wetblowdryer]

Hello,

 

I have recently gotten back into the hobby of flight sims. That's fine and all, but they're taxing on your PC no matter what. Currently, I have a 9600k, paired with a z390 Gigabyte Aurorus Pro Wifi MoBo, 32 GB RAM, and a GTX 1080 ti. First world problem, I know, but I cannot get my 9600k past 4.7. No matter the voltage, all the way up to delivered 1.4v, it doesn't stay stable past 4.7. I've disabled multi core enhancement because I read that can sometimes cause issues. Temps are fine, below 65 even with 1.4v delivered. Some help would be greatly appreciated. Thanks.

You can try making the avx offset slightly negative. If that doesn't work, then you'll need to increase the voltage of your cpu.

Update the BIOS before doing anything

Done. Forgot to do that.

Ehh I'll try that as a last resort. As for the voltage, absolutely not, since 1.4v seems to be the agreed upon max for Coffee Lake CPUs. While not all 9600k's can reach 5 ghz, I thought a dud could at least reach 4.9 at 1.4.
