Notes on Intel Pentium III 667 MHz
  • The processor is usually marked as 667/256/133/1.65V or 667/256/133/1.7V, where the last number specifies processor's core voltage. If the processor is marked with RB80526PZ667256 part number then use processor specification number to identify processor's core voltage
  • Stepping cA2 CPUs for Socket 370 were not validated for dual-processing
