Hi Everyone, I'm having a weird problem with my Asus Prime Z390-A and my new 9900k. When I try to use manual voltage, I need a load line calibration of level 6 or 7 for the voltage to be correct. For example, if LLC is at level 5 and the voltage is set at 1.28 V in the BIOS, the motherboard will only output 1.27 V in the bios and the system crashes when I try to run a stress test. This problem gets even worse as I lower the LLC setting to a point where it won't even load windows at level 2. I originally had a 9600k a few days ago, which I exchanged for the 9900k, and everything worked perfectly at and LLC setting. I've tried resetting to default and I also cleared CMOS but it is still the same.
Does anyone have any ideas what is causing the problem? I know the VRM's are not the best on this board, but I originally purchased it for the 9600k not the 9900k. I'm still within the return period of the MOBO so I can exchange it if for a better board of that's the problem.

CPU: 9900k A 5.0 GHz
