133 Processor in a BX100 Motherboard?

I found out that I can clock up to 650 MHZ with my current 440BX Slot 1 motherboard.

I also found a good deal on a slot one 667 CPU from buy.com...

So, can I put a Pentium III 667 Slot 1 CPU in a Iwill BD100 motherobard that will only clock up to 100 MHZ for the FSB and 650 for the CPU clock?

I guess I'm asking if the CPU's that have a 133 FSB, will they clock down to 100 without any problems?...

There are a couple of problems you might encounter
at 133 mhz
- you will need 1,65 Vcore
- your agp bus will certainly run at 89 MHz, check your videocard - if it is a geeforce it is able to handle it
- PC100 Ram is probably sufficient
- If the processor is an EB (flipchip) you'll need a slotket (convertercard), buy one with vcore jumpers
-you will need another mobo if you want to hit 133 mhz

and yes... there are people on earth stupid enough to buy a 667 (E)B processor to run it at 5X100 on that mobo instead of a 566 mhz celeron (2) that easily will hit 8.5 X 100 mhz (higher multipliers aren't a problem for the mobo

in other words... if you want to stick a P3 in there, you would be far better off getting a 650E that runs at a native 100 fsb rather than a 667EB that runs at 133.

Which motherboard? If it only handles a max of 100 FSB (assuming it runs Coppermine at all) then:

PIII 667 will run at 500 MHz.
PIII 650 will run at 650 MHz.

On the other hand, if it runs a 650, it will also most likely run an 800E, at a nice 800 MHz...
