Put a USB stick in your computer, turn off computer, enter bios, hit printscreen or maybe its F10, and it will save a screenshot to the USB stick.
You SHOULD be able to just enable XMP however. I have nearly that exact same motherboard, once you get into the advanced bios mode it should all be easy.
Also ensure you're looking at the right page in CPU-Z a lot of people confuse the page showing SPD values as the speed the memory is running at.
