I hope this question lies within the guidelines.

I have acquired this AMD 5600x for a very low price. It was dropped on the corner (see picture) where we can see some delamination. Seller just says it does not work anymore, I have not tested it myself yet. I will try 1 memory stick and the normal debug before the questions/solutions below are considered!

None of the pins are bent. I think the subtrate PCB is 12 layers all vias are buried. The damage does not go "underneath" any of the pins. A couple of questions:

• Would the layout engineer be forced to route this close to the edge? Beyond where the pins are?
• Can i use a multimeter to test for short circuit on a device that could take 200 Amps at ~1.4 volt maximum? Would the multimeter test with too high voltage?
• Should I try and tape the corner back together (if the copper/via is ripped this would be a shaky solution)
• Or should I dremel it pretty and perhaps remove a circuit between the layers?
