Notes on Intel Pentium III 1BGHz (Socket 370)
|
-
The processor is usually marked as 1000/256/133/1.7V, 1000/256/133/1.75V or 1000/256/133/1.76V, where the last number specifies processor's core voltage. If the processor is marked with RB80526PZ001256 part number then use processor specification number to identify processor's core voltage
-
This part is usually referred to as 1B GHz or 1.0B GHz CPU
