2011 iMac Panic
I have a 2011 iMac that is crashing about one time a day. There does not seem to be any consistent actions that trigger the crash.
Some changes to the iMac are below:
-20GB RAM (stock 4GB + 16GB from OWC)
-SSD conversion from OWC
-2600S CPU swap
-Nvidia 2100M swap
-Running Catalina
The most recent panic report is below (continued in Crash 1) and more are attached (additional available if necessary).
Could someone help identify what is causing this issue, and how it can be resolved. Is it due to the changes above, or is it due to a faulty logic board that needs to be replaced?
