Intel Pentium III 733 Mhz SL3XY SMP CPU


This CPU is an Intel Pentium III 733 Mhz SL3XY CPU and is a fast option for Socket 370 mainboards. You can use it on Slot 1 mainboards too, if you put it into an Socket 370 to Slot 1 adapter. If you need one adapter along with this CPU, feel free to ask, and we will include one for free.    

It was tested in a Slot 1 mainboard using a Socket 370 to Slot 1 adapter  and is working fine. 

 If you build a Socket 370 or Slot 1 system, this is your point of reference. It works in almost every Socket 370 mainboard and some Slot 1 mainboards which can handle the speed.

This CPU can be used in a 2 CPU SMP configuration. No need to use Celerons for that, if there i  real Pentium III available with full cache.





Under the picture you can find the specs of this CPU.

Notes on Intel Pentium III 733 MHz
  • The processor is usually marked as 733/256/133/1.65V, 733/256/133/1.7V or 733/256/133/1.75V, where the last number specifies processor's core voltage. If the processor is marked with RB80526PZ733256 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
