Question Gigabyte Auros z490 Ultra RAM/boot issue

[Qehljilu]

Hi! I just came home from a long day and booted PC. It gave me the attached image:

Boot Error Message

I pulled out ram slot a_2 and b_2 and it could boot.

I found out that a_2 had been loose, when I pulled it out. The upper pin was off (I had my pc in the car for a LAN, so it prolly detached itself there)

How do I reinstall my ram? Is one defect? I dont even know what the message on the screen means. But I guess it means a_2 is fried.
Help!

How many ram sticks do you have?

If it's 2 follow the recco in your pic.
If it's 4 fill all the slots.
Test.
