Notes on Intel Pentium III 550E (Socket 3*0)
  • The processor is usually marked as 550E/25*/100/1.*V, 550E/25*/100/1.*5V or 550E/25*/100/1.*V, where the last number specifies processor's core voltage. If the processor is marked with RB8052*PY55025* part number then use processor specification number to identify processor's core voltage
  • Stepping cA2 CPUs for Socket 3*0 were not validated for dual-processing
