Here is a reference link for all processor types from Intel.
And Processor Socket Types:
For the Pentium III class from Intel.
For the Pentium II class from Intel.
The core voltage ranged from 1.35 volts to 1.75 volts.. and some early models used a 2.0 volt core.
The Pentium II and Pentium III class were somewhat interchangeable, if in the cartridge package.

There are socket adapters known as "Lin-Lin" that allow setting the voltage/bus ranges with jumpers.. for some non-supported processors on some mobos.

quite right. I missed out the word 'coppermine' from my last post - hence totally confusing the issue and taking this post rather OT, my apologies.

The point I was making was all coppermine celes were socket 370, whereas the PIII coppermines came in both slot 1 and socket 370.

Back OT, if you want to try OCing that cele, try getting your hands on some PC100 RAM, with a bit of luck you may be able to run it on a 100Mhz bus, but the usual overclocking risks apply.

Not all processors that "fit" the socket class are compatible.
Certain pins on the newer CPUs are for specific keying to control the core and I/O voltage, bus speed and ratio. Plus access to internal cache memory.
A few of the Socket 370 and Slot 1 setups had some jumpers to set.. but most of the models used an auto-set process. With today's socket types, there seldom is any controlling jumper on the mobo that is for the CPU setup. Almost all feature control is via the 'soft-set' from the BIOS pages.

Yes, the early P2's/370's had a few jumpers to set. My first Intel P2 board had a setup jumper which you had to short then go into the Bios and change the speed. Setting up an Asus 333 board was a nightmare but compared to some Super Socket 7 boards even that was a piece of cake
