What frequency are you trying to achieve?
What is BIOS setting for SA and IO voltage?
You could try the AI OC in the BIOS. My setup is OCed at 4.8GHz for light work and 5.0GHz under heavy load automatically with a 25% overall OC using the builtin AI OC setting. The system tries many profiles to find the most stable OC for your specific system depending on your cooler efficiency, RAM and CPU quality etc. It's worth checking out before you try a complete manual OC with XMP etc. just to see what your system can achieve with the artificial intelligence OC system built in our Z390 ROG Maximus XI series mobos. Even der8auer, who is a well respected OCer on YouTube recommends trying it out. Check out his YT channel for details here:
