i9 9900K and Corsair Vengeance RGB PRO DDR4 2x8GB

Hello good people.
I've built my first PC and looks like my RAM is too fast for the CPU.
I know you can overclock stuff to make it work, but I have no experience
in overclocking and don't wanna fry anything.
So my CPU is Intel Core i9-9900K with DDR 4 2x8GB 4266 MHz (2 kits - 4 bricks all together)
After I activated XMP in Bios, the computer was unstable and crashing.
From what I read and if I understood correctly - the RAM was operating at too
fast frequency for the CPU to handle it (?)
After I deactivated XMP, computer runs very well - but I'd like to get more performance
out of the computer.
Would you guys help me and give me some guidance how can I overclock this thing
and have stable machine at the same time ?

Hey Kung- fu.
So I did some research and find out that CPU shopuld be OC-ed first - correct ? (And it isn't)
Yeah I have 32 GB of RAM - I work as a pro photographer so I need that juice
And yeah - after activating the XMP I didn't check if voltage was increased or not, but on Corsairs website I checked specs and
that 4266 MHz speed was tested at 1.4 V. So probably 2 things I didn't do correctly:
1. CPU runs on default speed
2. RAM probably didn't have enough voltage.
Please DO correct me if I'm misunderstanding anything.

Makes sense.
You know what ?
I should think about it earlier: I'll just ask Corsair what equipment they've tested that RAM speed on and see what they say.
