There are lots of overclocking guides if you want to try that, but you might need to change a number of settings and voltages in the BIOS.
If your knowledge is limited at this point, I would suggest that you set the BIOS back to default values and then if that works OK, try turning on XMP in BIOS to increase your memory speed. Again, if everything is stable, then that's really all you need to do at the simplest level. If not, turn XMP off again and then start reading about memory settings. You have a great CPU, RAM and GPU, so basic settings should give you a super fast system anyway. The automatic AI overclocking is a good idea, but it's not guaranteed to work every time and sometimes, further adjustments are needed.
The best way to proceed is first to find settings that are stable for you, make a note of them and take it from there. Also run some memory tests using MemTest86 in the BIOS menu with XMP off and then do it again with XMP turned on. Then you will know if your memory is running stable.
If you still want to overclock after that, then that's all good, but best read some guides, watch some videos etc. If you have specific questions once you have tried, then I think it will be easier for people to help you... you will then be able to describe what you tried and what happened.
