• Fake cache

The motherboard may include a non-functional or counterfeit SRAM cache, which can adversely affect performance. Signs of fake cache often include soldered DIP-chips and no jumpers to set the chache size. Cache functionality can usually be restored by installing proper chips, jumpers and a BIOS update/mod.

• Faulty or Leaking Electrolytic Capacitors

Some motherboards may contain faulty or leaking electrolytic capacitors, which can negatively impact system performance or stability. These capacitors may exhibit issues such as bulging, leaking, or even exploding, potentially damaging other components on the motherboard. Users should inspect their capacitors regularly and replace any that are faulty or leaking to avoid damage or system instability.

The PM-8400D has a different I/O chip. Pay attention when flashing your BIOS.

The soldering is poor. Check for cold solder joins on big components and capacitors.

Some examples of this board are known to have fake cache, but potentially not all.
