iMac crashes randomly

My iMac crashes randomly. I have no idea what's going on.

I'm using the original 8g ram with 32GB (16GB x2) OWC Memory 2666MHZ DDR4 SO-DIMM PC4-21300.

Does anyone have any idea? Thanks in advance.


iMac 27″, macOS 11.3

If the RAM is reported, bring it in to Apple Service center to remove the RAM. At least there they can make sure all the proper static electricity precautions are taken, plus are less apt to damage the logic board.


One thing to note, it is generally best to run RAM in even pairs. Configurations of mixed module types can cause problems.
