| Notes on Intel Pentium III 750 MHz |
- The processor is usually marked as 750/256/100/1.65V, 750/256/100/1.7V or 750/256/100/1.75V, where the last number specifies processor's core voltage. If the processor is marked with RB80526PY750256 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
