Quick question,
It looks like my board is defective. I tried another CPU (swapping my 10980XE for a 9900X) and problem persists and swapped RAM, GPU, PSU and it’s just not stable with any RAM or any capacity of RAM that has an option for XMP (even when disabled and clocked down all the way) - it used to work fine.
So right now, I have iMessage / all the iCloud stuff working with my serial number. If I get a replacement of the same board (if that’s what ASUS gives me the option to do) - do I need to generate a new serial number or can I just leave all that as is?
