You're right to notice the slight curve in the contact pins. This can be normal depending on the design. The issue with booting and the LED indicating a DRAM problem might point to another fault, so it's worth checking further. The working lights suggest other components are functioning properly.
I understand, but it's pretty interesting and it cost a fair amount of money when I purchased it.
It seems you're referring to uneven pin lengths on a stick and possibly trying to install a Zen 2 CPU on an MSI board that requires updates.
