Known Issues
Poor CPU stability and/or bulging/leaking VRM Vcore bulk capacitors
Causes
- VRM Vcore bulk capacitors degrade from prolonged use especially when PC case has poor airflow from dust buildup and failed fans
Solutions
- Replace VRM Vcore bulk capacitors
Disassembly Notes
- Handle PCB by edges to avoid stressing BGA devices or touching static sensitive devices
- Use ESD safe equipment
- This PCB is a high density multi-layer PCB with a high thermal mass, some soldering irons may struggle
Original Parts
VRM Vcore
VRM Vcore capacitors will vary wildly depending on manufacture date of your PCB, some will have all the same wet electrolytics, some including mine will have a mix of wet electrolytics and polymer capacitors.
